What can you do if your iPhone has poor network reception?

Often iPhone users have to deal with a problem: the gadget does not find the operator’s signal. Cellular communication is the main function of the phone, so it is important to understand the cause of the breakdown. If you are confident in the operation of the SIM card and your telecom operator, then you need to check the functionality of the device itself.

What to do if your iPhone has poor network reception? Let's consider several ways to solve this issue.

The first thing we do is reboot the device. Experienced PC users know that when a computer freezes, rebooting is the first step to restoring operation. It is worth noting that sometimes the signal disappears due to 3G being turned on. Most likely, the problem arose in the latest iOS update.

If the restart does not help, we perform the methods given below one by one.

Setting the time zone

As a rule, the cause of the malfunction is an incorrectly set date and time. Take the following steps for proper setup:

• Connect your iPhone to an active Wi-Fi network.
• Open the phone settings, then in the “General” menu go to the “Date and time” item.
• Activate the "Automatic" line. If the function is already activated, turn it off and on again.
• Wait about a minute, then reboot the device.

It happens that the operator is not able to do his job efficiently due to the remoteness of the area. Select the “Airplane mode” line in the menu and turn it on for 5-10 seconds. After disabling this mode, a network search will occur.

No network after firmware update, iOS update, factory reset

Sometimes it happens that after repairing the device, updating the operating system, flashing it or resetting it to factory settings, the iPhone loses the network and the operator logo does not appear on its display. Instead, you may see the message “Searching” or “No network” on the screen. This is especially true for iPhone models 7 and , as well as earlier models 4, 5 and 6. First of all, in such cases, you should make sure that the SIM card is working properly. To do this, you just need to install it in any other phone.

If the SIM card is working, but the problem remains, you should pay attention to the correctness of the time display on the device display. If the current date and time are displayed incorrectly, which happens quite often after the smartphone is repaired in a service center, as well as after independent flashing or updates, you must perform the following steps:

• connect to Wi-Fi;
• go to the “Settings” menu item;
• in the “Basic” submenu find “Date and time”;
• move the “Automatic” slider to the active state;
• if this item is active by default, deactivate and reactivate the slider;
• restart your smartphone.

It should be remembered that the phone must be connected to the Wi-Fi network, otherwise no changes will occur to the cellular network.

If there is no access point nearby, you can create a Wi-Fi connection using a second iPhone that has access to the mobile Internet. You can do this as follows:

• enter the “Settings” menu and go to the “Cellular” menu;
• click on “Cellular Data Network”;
• go to the “Modem Mode” section;
• In the APN field, enter the network identifier, which can be found in the technical support of your operator;
• The “Username” and “Password” fields are optional;
• return to the “Cellular Communications” submenu and set the “Modem Mode” slider to the active state.

After these manipulations, the gadget will begin to “distribute” the Internet.

Installing system updates

For the device to function correctly, it requires software updates. Perhaps the iPhone does not see the network because these updates arrived on it, but you did not install them.

Connect to the Internet, go to the “Basic” settings menu again, then the “Software Update” line. If you can't connect to the Internet on your phone, you can complete this step through your computer while connected to iTunes.

Searching for a network after factory unlocking

When restoring, updating, or activating a smartphone, a similar problem occurs. The way to fix it is very simple: you need to reset the network settings. The fact is that your phone sees the SIM card itself, but cannot catch the regular network, so in the main parameters we find the line “Reset” and then “Reset network settings”. If the harmless option does not bring the desired result, perform the following steps:

• We connect the smartphone to the computer and open iTunes.
• Back up your files and click on “system restore”.
• After completing the recovery procedure, you will be asked to either restore the copy of the iPhone that you made, or use it as a new device. You must choose the second option.
• After the whole process, the phone will start searching for a network.

If a problem appears when using the SAMPrefs or RedsnOw programs, we recommend contacting a specialist, since an independent solution does not guarantee a 100% positive result.

How to avoid network problems in the future

In order to protect yourself from such problems in the future, you should take care of the device: do not drop it to avoid mechanical damage to the receivers and transmitters, keep it away from moisture. You should also refrain from buying cheaper Chinese copies, since in such devices problems with finding an operator’s network are much more common. It is most advisable to buy original iPhones, a wide range of which is presented among Apple products in our online store.

The reason is the coverage area

The iPhone is a popular product, so it is not surprising that counterfeits and defects are common. It is also possible that your phone was imported into Russia unofficially and works strictly with a specific telecom operator.

As you can see, there are various circumstances that affect the operation of your iPhone. If your iPhone has poor network reception, it’s quite easy to solve the problem yourself. If the above methods did not help, seek advice from a specialist.

iPhone is considered one of the most popular mobile phone brands in the world. Models under this name are quite expensive, but this does not stop many people who are sometimes ready to go into debt, take out loans, and incur other personal complications for the sake of a coveted gadget. Therefore, it becomes a shame if unexpectedly your beloved iPhone becomes worse at catching the network.

Naturally, this seriously limits the functionality of the device. Therefore, you should quickly get rid of the trouble. Sometimes you can achieve the desired result with your own hands. And in our article we will try to tell you what exactly can be done in such a situation.

iPhone XR problems

Problems with LTE turned out to be one of the most, if not the most, common problems with the iPhone XR

Before I looked at the lawsuit, I was sure that its authors were not satisfied with the appearance in iOS 13 of a mechanism for reducing performance when the iPhone XR battery reached a critical level of wear. However, as it turned out, their claims are completely different, and, to be precise, in the hardware imperfections of the smartphone they discovered.

Apple has launched a Smart Battery Case replacement program for iPhone XR, XS and XS Max

It turns out that the plaintiffs were unhappy with the fact that Apple equips the iPhone XR with antennas that support MIMO 2x2 technology, while the iPhone XS and XS Max are equipped with MIMO 4x4 antennas. Without going into technical details, the difference between them is the higher throughput of the latter. As a result, the Internet connection speed of iPhone XS and XS Max will always be faster than that of iPhone XR, even when using LTE networks of the same operator.

Possible root causes of such trouble

It is useful to know the reasons why your phone may not have good network reception. Sometimes this will allow you to find a solution to the problem that has arisen. The root causes may be the following:

• The situation began to occur after the next firmware, which the user could install independently and incorrectly;
• The gadget was recently sent for repair, where the service was not of high quality;
• The coverage of the operator providing the mobile communications service at the person’s location is poor. This is especially evident when the owner of the mobile phone is indoors;
• The SIM card you are using is incorrectly installed or does not function fully for some reason;
• The presence of any hardware-type limitations associated with external factors;
• There are problems with the version of the operating system you are using;
• Damage to the element responsible for communication.

Some of these problems cannot be solved on your own, others can be tried.

Solution

So, it’s worth immediately dealing with those cases whose solution does not depend on the actions of the smartphone owner:

• Poor coverage. We'll have to come to terms with this for a while. Or try to find a higher, open point where the signal can be picked up;
• If the SIM card malfunctions or does not work well, you will need to change it at the nearest communication store - and this will be the only solution;
• If troubles begin to arise after poor-quality repairs, it is recommended to take advantage of the provided warranty or go to another service center. You should do the same if you suspect that the modem part of the gadget is faulty.

Another interesting situation is that a person could purchase a mobile phone that was initially “tailored” for the work of a specific operator. This situation usually arises when people order equipment abroad. In this case, it will also not be possible to fix something on your own. You need specialized software and the ability to work with it. Usually, everything you need can be found at repair services. How to check exactly such a case? In the following way:

• Visit the settings section, where you go to “General”;
• Click to go to the “Standards” tab. At the very top of the screen information on the modem used in the equipment will be indicated;
• Option A1901 allows the use of GSM networks, including those used in the Russian Federation;
• But the A1902 and A1858 are designed to work with CDMA networks used only in Japan, China, the USA, and Oceania. That is, it will not be possible to launch it in our country without professional intervention.

What to do if iPhone X has poor network reception

The quality of communication determines the comfort of operation and even the life of the battery. As a rule, network problems are the fault of third-party factors.

Need iPhone repair - call us, we will help!

By likelihood of occurrence:

• Problems with carrier coverage in a given region (obvious, but worth checking)
• Problems with the SIM card (damaged, incorrectly cut, expired - it wouldn’t hurt to replace it at the operator’s salon)
• Hardware limitation (example: when driving fast in a car, the iPhone does not have time to switch between towers efficiently)
• Problems with iOS (solved by resetting the network settings, flashing the firmware - more on that below)
• Hardware malfunction of the modem, modem part - repairing the iPhone X in the service is the only way out (diagnostics required)

What to do in other situations?

The first method can help when the iPhone has poor network reception. That is, it seems to be there, but everything is functioning extremely unstable:

• Go through the telephone settings to the section called “Basic”;
• Scroll the page on the screen to the very bottom and use the “Reset” button;
• The user will be offered several options. You need to click on “Reset all settings”.

After these steps, it is recommended to visit the settings menu of your mobile phone again and find “Cellular Communications” there. Go to the section, at the very bottom of the new screen, deactivate the “Wi-Fi Assist” function.

Additionally, it is worth checking the version of the operating system and updating it automatically to the latest, current version.

The second method must be used when the connection is not observed at all:

• First, make sure that the card is installed in its slot correctly. And it is cut exactly the way it should be. It is also recommended to test performance on a guaranteed working SIM card. If the failure is resolved, then, as already written above, you will need to replace the SIM card with a new one at the nearest branch of the mobile operator you are using;
• It is also worth trying to turn on your mobile phone without a card. If at this moment the gadget attempts to connect to some network, then this is a clear sign of a malfunction of the internal modem. The problem can only be corrected in a specialized workshop.

It is also worth listening to the following recommendations:

• Make sure that the correct time settings are set on the device. If this is not the case, then change the date and time parameters in the corresponding section of the settings menu;
• If it is impossible to connect automatically, go to the menu responsible for this tool and switch to the manual search method. Naturally, you will need to know the name of the network needed to connect.

Software problems

It cannot be ruled out that when the iPhone says “No network” on the display, this is directly related to software errors. In most cases, they are corrected by the developer himself.

When releasing the next version of a mobile operating system, it is thoroughly analyzed for errors and vulnerabilities. If they are detected, adjustments are made to the firmware, and these changes are sent to users along with other additions in the form of updates.

Therefore, the first thing you need to do when you don’t know why the network suddenly disappears on your iPhone is to update your smartphone by installing the latest available firmware on it.

Reboot

Oddly enough, very often a banal reboot of a smart phone from Apple allows you to restore its normal functionality.

This is due to the fact that we are talking about electronics and numerous ongoing processes. It's the same with a computer. Active work, performing a large number of tasks lead to the fact that the device is heavily overloaded, experiences serious stress, and, one might say, gets tired. To relieve all the ballast of a hard day of work, people need to sleep. And machines, including computers and smartphones, will reboot.

To restart your iPhone, just hold down the power button and then turn on the device again. During the reboot process, the network settings are reset, and the network may well appear.

Resetting network settings

Often, when a notification about the absence of a cellular operator’s network appears on the screen, a solution such as resetting the network settings helps.

To reset network settings on a smart device such as an iPhone, you must:

• open the main settings menu by clicking on the corresponding icon on the desktop;
• go to the “General” category;
• then find the “Reset” section;
• In the presented list of available actions, tap on the “Reset network settings” item.

A reset will occur and the phone can function normally again. Sometimes it is additionally recommended to restart the device. A combination of these actions brought the network back to the iPhone many times.

Factory settings

We are talking about resetting the phone to factory settings. iPhone users should understand that in addition to system software problems, as well as potentially malware that caused the phone to suffer, photos, videos, installed games and everything else will be deleted.

Therefore, it is recommended to resort to such a solution, if the device simply does not see the network of the cellular operator, as a last resort.

Flashing

But you shouldn’t be afraid of updating the current firmware on your iPhone. Moreover, this is a useful and sometimes simply necessary procedure that has a positive effect on the operation of the device.

You can update directly through the gadget settings. Or the phone is connected to a computer on which the iTunes application is installed. Next, the program should recognize the connected device. By opening the “Overview” tab, all the characteristics of the smartphone will be displayed here, including the firmware version. By clicking on the “Update” button, the latest firmware will be installed on the iPhone, if available.

Reviews from people

Reviews from owners of such equipment allow us to understand exactly how they dealt with a similar failure:

1. Semyon. One day an acquaintance who lives in another city came to visit. And he unexpectedly offered to buy a sixth series iPhone from him inexpensively. The price was reasonable for me, the phone itself looked fine. So I took it. At first everything seemed to work. After some time I stopped seeing the signal. I opened it and replaced the device responsible for reading. It seems like the glitch has been fixed. But only if the mobile phone is used outdoors. The connection indoors is very poor. I started to look into it further. It turned out that this phone had already been repaired a couple of times. And they didn’t do it very professionally. The reason was found to be a modem whose contacts were poorly connected. And after some time they completely moved away. Corrected. Now everything works fine.
2. Oleg. They brought me an iPhone 5 from the USA. Not new, has already been in use for quite a long time. I immediately noticed one problem - everything works stably in 3G, but when this function is turned off, the connection begins to be lost. And this is when installing a SIM card from any domestic operator. I took the smartphone to a friend of mine. He looked and determined the root cause of the failure. It turned out that some ceramic filters on the antenna in use were damaged. He completely changed this element and the original situation has not been observed for three months now.
3. Matvey. I've been using 5S for several years now. And I’m constantly faced with a situation where I stupidly can’t get through to someone. Or they later tell me that I was unavailable. Although the full signal seems to be shown, the Internet works flawlessly. Finally, I decided to figure it out. I met an acquaintance who is “rummaging” about this. He looked a little and made a verdict. Firstly, he said to be sure to replace the card with a new one. I got it from MTS - he said that with this operator they often create problems after prolonged use. Secondly, remove the case you are using and forget about it altogether. The thing is that it is metal. And it turned out that the case shielded the signal. Especially indoors, where the coverage is always worse than outdoors.

That is, sometimes the root cause may be some annoying little thing. And the solution is not always to go to a workshop, where the master will ask a fairly significant amount of money for the work done.

If your iPhone does not connect to the network, you should not immediately panic and look for a suitable service center. Perhaps the problem is not worth a damn. What can cause the loss of GSM signal on an Apple device?

Finding yourself “in your hands” with an iPhone that does not catch the network on any trip or business trip is not a pleasant situation. The boss will be annoyed that his employee is unavailable and did not submit a timely report, relatives will be worried, potential clients will be off the hook. It will be impossible to even call help or a taxi if something happens to the car. It should be recognized that modern man is heavily dependent on the GSM signal.

Fortunately, in most situations you can solve the problem of a weak network on your iPhone yourself and quite quickly. In this article we will talk about common reasons why an Apple gadget has poor network reception and ways to correct the situation.

Checklist for choosing a reliable service center for repairing Apple equipment

Prices

Fair, not overpriced and not underestimated. There should be prices on the Service website. Necessarily! without asterisks, clear and detailed, where technically possible - as accurate and conclusive as possible.

Deadlines

If spare parts are available, up to 85% of complex repairs can be completed in 1-2 days. Modular repairs require much less time. The website shows the approximate duration of any repair.

Warranty and responsibility

A guarantee must be given for any repairs. Everything is described on the website and in the documents. The guarantee is self-confidence and respect for you. A 3-6 month warranty is good and sufficient. It is needed to check quality and hidden defects that cannot be detected immediately. You see honest and realistic terms (not 3 years), you can be sure that they will help you.

Stock

Half the success in Apple repair is the quality and reliability of spare parts, so a good service works with suppliers directly, there are always several reliable channels and your own warehouse with proven spare parts for current models, so you don’t have to waste extra time.

Free diagnostics

This is very important and has already become a rule of good manners for the service center. Diagnostics is the most difficult and important part of the repair, but you don't have to pay a penny for it, even if you don't repair the device based on its results.

Service repairs and delivery

A good service values ​​your time, so it offers free delivery. And for the same reason, repairs are carried out only in the workshop of a service center: they can be done correctly and according to technology only in a prepared place.

Convenient schedule

If the Service works for you, and not for itself, then it is always open! absolutely. The schedule should be convenient to fit in before and after work. Good service works on weekends and holidays. We are waiting for you and working on your devices every day: 9:00 - 21:00

The reputation of professionals consists of several points

Company age and experience

Reliable and experienced service has been known for a long time. If a company has been on the market for many years and has managed to establish itself as an expert, people turn to it, write about it, and recommend it. We know what we are talking about, since 98% of incoming devices in the service center are restored. Other service centers trust us and refer complex cases to us.

How many masters in areas

If there are always several engineers waiting for you for each type of equipment, you can be sure: 1. there will be no queue (or it will be minimal) - your device will be taken care of right away. 2. you give your Macbook for repair to an expert in the field of Mac repairs.

Here you can always, in an informal setting, look at the life of the service from the inside, evaluate examples of repairs, and communicate with specialists live. It’s convenient, and now you simply can’t live without social networks

Faces of the company

Apple's seasoned experts and engineers are superheroes, but they don't wear masks. On the website and on social networks you can always see who you are going to, see photos and learn a little about the engineers and service managers. You can write to each of them, suggest or clarify something with someone with whom you have already communicated.

Reviews

You can understand a lot from reviews if you treat them correctly. The overall assessment of the service should be positive and high. But the rating cannot be maximum. Reviews can be both positive and negative, the main thing is that they respond to them, communicate, make decisions, help, that is, treat them like a human being.

Ask a Question

The time is set incorrectly

The first thing you need to check on an iPhone that does not receive a GSM signal is the date / time settings. If the settings are incorrect, you should set the correct ones manually . This is done like this:

Step 1 . Follow the path “Settings” - “General” - “Date and time”.

Step 2 . Find out the exact time in your time zone. To do this, you can use, for example, the Yandex. Time".

Step 3 . While spinning the reels, set the correct date, hour and minute.

Step 4 . Restart your iPhone and check the network.

If you have access to Wi-Fi, you can avoid manually setting the time. In the “Date and Time” subsection there is an “Automatic” slider. After activating it, the iPhone independently determines the time in the set time zone - but only if the gadget is connected to the Internet.

Your humble servant prefers not to use automatic time adjustment, because his iPhone “counts” an hour too late.

Problems with mobile operator settings

If the time is set correctly, but the iPhone still does not receive the network, you can suspect that the settings of the cellular operator have gone wrong. A set of such measures will help solve this problem (each subsequent step should be performed only if the previous one did not produce results):

Step 1 . Turn airplane mode on and off. The corresponding slider is located at the very beginning of the Settings menu.

Step 2 . In “Settings”, go to the “Operator” section and deactivate the “Automatic” toggle switch.

Step 3 . Check if the cellular data settings (APN, username, password) are entered correctly. Follow the path “Settings” - “Cellular Communications” - “Cellular Data Network”. The “Cellular Data” block contains the necessary details.

You will find the correct settings for the 3 leading operators in our article on how to set up the Internet on an iPhone. If there is a discrepancy, change the cellular data settings on your Apple gadget manually. After changing the settings, be sure to restart your device.

The smartphone connects to the network, but the signal is unstable (the network itself disappears and appears)

If you notice that the quality of your cellular connection has decreased , reset iOS to factory settings:

• Open settings;
• Go to the “Basic” section;
• Scroll down the menu and click on the “Reset” button;
• Select “Reset all settings”.

It is also worth turning off the “Wi-Fi Assist” feature, as it may cause an unstable connection:

• Go to settings and open the “Cellular” section;
• Scroll down the menu and turn off “Wi-Fi Assist.”

Cellular service interruptions are a common problem with early iPhone Xs. To improve stability, update to the latest version of iOS.

Weak GSM signal

If the reason for the weak signal is that the user’s location is not within the GSM coverage area, you cannot fix the problem yourself. You will have to buy a SIM card for temporary use. Although in fact, the territory where there absolutely no GSM signal still needs to be looked for.

There are areas where the signal is very poor in large cities. As a rule, iPhones are not detected in the subway, basements, or elevators. The network may disappear inside the building due to the fact that the concrete walls of the room jam the GSM signal. Some buildings deliberately use “jammer” devices to prevent employees from excessive Internet surfing. The jammers look something like this:

Previously, “jammers” were readily placed in educational institutions. Now the use of such devices has been reduced to a minimum - the modern educational process requires the student to actively access the mobile Internet.

If the GSM signal is weakened in the user's home , this is a reason to file a claim with the communication provider. The iPhone owner needs to call the hotline number and complain about the lack of network. The application will be transferred to the technical department, whose employees will make every effort to resolve the problem.

Causes of problems

If the owner has a question about why there is no network on his iPhone, this is the first time he has encountered such a situation. Experienced users already know roughly what can lead to such a situation, and therefore do not panic, but start working.

For beginners, it is important to know exactly why their iPhone does not receive the network, since there is a need to make a call and connect to the mobile Internet. But without a network this cannot be done.

There is more than one problem that causes the iPhone to display the message “No network.” But what exactly it is, we need to find out.

Most often, problems arise for the following reasons:

• this is an illegally imported mobile device that is locked to a specific operator;
• there was a failure at the software level;
• there are problems with the cellular operator;
• hardware problems have occurred.

You need to start by looking at the display. The status “Searching” or “No network” may be displayed here. Check for signal. The easiest way to do this is by checking its presence on another device. Before doing this, enable the auto network search function through the iPhone settings.

SIM card is damaged

Mechanical damage to the SIM card or improper cutting cannot be the reason why there is no network on the iPhone. If the card is faulty, the SIM gadget will not recognize it at all. This is a completely different problem, the possible solutions for which we proposed in the article “Why the iPhone does not see the SIM card.”

However, a user suffering from a lack of network on a smartphone should still conduct a visual inspection of the SIM card. If there is dirt on the contacts, you need to carefully remove it. Even the fact that the user removed the SIM card and installed it back in the slot can help restore a normal GSM signal.

If the owner of an iPhone has suspicions that the gadget has poor network reception due to the SIM card, he should contact the service office with a passport and have the SIM replaced. This procedure is free and only takes a couple of minutes.

Why doesn't my iPhone see the SIM card and says there is no network?

Why Wi-Fi turns off on an iPhone - it loses the signal on its own

Various gadgets, for example, iPhone 5s, write: “no network.” There can be many reasons for the appearance of such an inscription. But often the problem lies not in the device, but in the SIM card. First of all, you need to check whether the phone is able to find it. If the answer is no, you need to try to extract it.

No SIM card

Often the problem is solved by moving inside the slot. The following types of problems also occur, some of which the subscriber is not able to solve on his own, so repairs may be required.

The time or time zone on your iPhone is set incorrectly

Often, modern gadget models, for example, the iPhone 7, which do not have modem firmware, lose the network after disconnecting for varying durations:

• during the flight;
• if the charger is lost;
• during repairs after a fall has occurred.

In this case, the situation can be corrected fairly quickly. To do this, follow the following sequence of actions:

1. Find and connect to any available Wi-Fi network.
2. In the main settings menu, select the “Date and time” line.
3. Find the “Automatic” item, which should show permission to auto-update. Move the slider to the right if it is not there.
4. Reboot the gadget.

Important! It is better to connect to regular Internet sources that are known.

After this, you need to turn on the phone again, which must correctly show the location (geolocation), time and, most importantly, search for the network.

Problems with mobile operator settings

iPhone 6 and other versions do not connect to the network due to the lack of operator settings. They become outdated quite quickly, so they need to be updated. Problems also arise when a new SIM card from another operator is inserted into the phone - it requires a complete installation of network settings.

Operator settings

To perform this operation you will need:

1. Find “Settings” on the desktop and go into it.
2. Select the “Basic” item, go to the next menu by clicking on the first line “About this device”.
3. If the required settings are available, you will be prompted to download them. The update will happen automatically once completed.

Important! To download, you need a stable connection to any Internet - mobile or Wi-Fi.

To confirm stable operation, in the same “About this device” tab, you need to look at the “Network” line. An operator (name) will appear in it, which means stable operation of the device.

Out of GSM coverage area

Sometimes the iPhone does not pick up the network only because there is no network in the given area. This can happen anywhere - in the city center or in a remote village, because the cellular operator and its coverage area decide a lot. If it is not powerful enough or is missing in some places, it will not be possible to solve the problem by standing still.

You can check whether this is the reason why the iPhone does not see the network. To do this, perform the following actions:

1. To check the operation of the operator in the subscriber's location, you will need an Internet connection via a mobile network. To do this, in the settings menu you need to find a line called “Cellular”.
2. The top line will offer a choice - turn on the gear and move the slider to the right (the green backlight will turn on) or turn it off by moving it to the left.
3. You need to try to switch to data transfer mode. At the same time, the Internet will turn on, and a letter indicating the pairing quality will appear in the upper left corner of the display. If this does not happen, there is a possibility that the signal is bad.

Additional problems may arise due to roaming - network search may be limited by the device if a restriction is set. To remove it, in the second line you need to check for the presence of the inscription “Roaming on.” If it is not there, activation is done in the same menu by dragging the slider to the right.

Faulty SIM card

If there is no network on any model, including the iPhone 7, this may indicate a faulty SIM card.

SIM card is faulty

You can check its operation by removing and reinstalling it. To do this you need to do the following:

1. Inspect the phone case around the perimeter. You need to look for a small point-hole located on the tray.
2. Find a paperclip or a special key and insert it into the hole, pressing slightly. The tray will open with force.
3. There will be a SIM card on it, which needs to be carefully inspected for damage or irregularly shaped scratches. If they are not there, you need to return the SIM card to its place by snapping the tray. Otherwise, ordering a new one from the operator will help correct the situation.

The answer to the question why the network constantly disappears on the iPhone may be demagnetization of the circuit. It is not visible externally, but replacing the SIM card with a new one will also correct the situation.

Note! The network may disappear due to the installation of a card that is incompatible with the device, so it is worth checking this point with the operator.

Software and iOS errors

An outdated version of the software may stop interacting with the cellular operator due to errors. This will lead to loading errors, failures in message transmission, and may also be the reason for the lack of network.

Updating the device to the latest firmware version can correct the situation. After loading the data, the gadget will ask for permission to install and reboot, after which the failure will be resolved automatically.

To check for an update, you need to go to “Settings”, and then find the “General” item. In the second line, near the words “Software Update”, you can see an exclamation point or other symbol, meaning that you are waiting for permission to install from the user.

Important! The update can be downloaded automatically if you configure auto-update in the same section by dragging the slider to the right.

If the software version is not outdated, but the network has not started to be detected, it is worth trying to restore the device. To do this, you will need to connect to your computer, then use the iCloud program to reset the current one and restore the last saved firmware version. An error occurring during the process may mean the phone is damaged and requires repair.

iOS crash

The failure of the above measures tells the user that the problem may lie in the software. For the gadget to work correctly, the latest system updates are required. To check if there are available updates, the user needs to follow the path “Settings” - “General” - “Software Update”.

If, as a result of the check, the iPhone finds newer software than is installed on the device, the user should download it. If there is nowhere to update further, you need to turn to the procedure for flashing the gadget. This procedure is simple and does not require contacting a service center - any user can perform it himself. To help a beginner, our article about flashing an iPhone.

What to do if nothing helps

If none of the above helped, then there is only one thing left to do: take the device to a service center. Only a specialist can help you find out the reason for the lack of network and help fix the problem. In most centers, device diagnostics are free and carried out in your presence.

Under no circumstances should you try to change parts yourself. If the problem is in the module or antenna, then you should trust a professional - these are very small parts in the housing that must be replaced with extreme precision and care. In addition, this procedure requires certain equipment. The only advice is to check on the official Apple website which service centers cooperate with Cupertino so that you can get a 100% good repair using original spare parts.
