The best-selling and most hyped smartphone of the last ten years is full of controversy. On the one hand, the iPhone reflects the innovative achievements of mankind, on the other hand, problems of a mundane nature arise, such as how to insert a SIM card into the iPhone and activate the network connection. Smartphones with other SIM cards require a battery; Apple took a different path and designed its own SIM installation system.
Preparing for the first launch of iPhone
Immediately after purchase, you should remove the phone from the box and inspect it. First of all, you need to pay attention to the equipment, which will always be the same if the phone was legally purchased from official dealers. The box should contain:
- smartphone in protective polyethylene form;
- Charger;
- USB cable for media synchronization;
- needle to open the slot;
- original Apple Airpods headphones;
- headphone adapter;
- decorative details (optional).
Also inspect the device for external controls. For example, the screen lock button on iPhones 5 and 5s is on the top, while on the 6 and 7 it is located on the right side of the phone. On the left are volume control keys and a quick switch to silent mode button. The main way to control the device is the central button, located at the bottom of the front side of the smartphone.
Different models have different types of headphone inputs. The 5, 6 and SE models have a standard 3.5mm input, while the iPhone 7 and all subsequent models connect to the headphones via the charging jack. You can use ordinary headphones left over from old models only if you have an original adapter from the manufacturer.

What size do you need?
Standard large SIM cards (rarely used in modern smartphones) are suitable only for first generation 3G and 3Gs models. Owners of second generation iPhones (4 and 4s) can use a micro sim. All subsequent models use a nano-SIM - the smallest of all existing ones. Its dimensions:
- length – 12.3 mm;
- width – 8.8 mm;
- thickness – 0.67 mm.
It is best to obtain SIM cards of the required size from the official center of the mobile operator, so as not to unknowingly damage the chip in an attempt to do it yourself. Perhaps this is only for receiving a micro-SIM. Nano-SIM is a different type of SIM in which the chip itself is smaller, so even if you completely cut off the plastic part, you won’t be able to insert it into the iPhone. Although there are craftsmen online who managed to cut a standard SIM card with scissors or a special stapler. It is not recommended to repeat their experience if you are unsure of your abilities.
Cards of the required size are issued on the same day without changing the number. Depending on your mobile operator, a replacement fee may apply.
For reference
The first SIM cards appeared in 1991 and from that moment on the era of phones with slots for them began. Their location and structure changed, becoming more and more convenient.
- The slot under the battery is recessed into the body or with a retaining one-piece (metal belt) fastening for the card.
- A slot under the housing cover, flush with the surface of the battery. The card holder is either one-piece or foldable.
- The SIM card slot exit is located on the side surface of the case, the hole is closed by a silicone plug. There is no tray yet - the card is inserted inside and recessed until it clicks, and is removed by pressing on (its) edge, as is done on digital cameras.
- The socket outlet is on the side of the case, there is a card tray - the most modern option. This is what we described in the instructions “How to insert a SIM card into an iPhone”.
This is interesting: Apple managed to step over the stages described in paragraphs 1 - 3, although the history of these smartphones began only in 2007. At this time and for several years after, devices from other brands produced the best ones with the sockets described in paragraph 3. For example, in the Samsung Galaxy J3 (2016), which already has quite serious “brains,” the SIM card was generally located in the old fashioned way, under the housing cover.
How to open the SIM card tray on iPhone
Users of smartphones and regular push-button phones are accustomed to the SIM card being located under the battery, but even the design of the iPhone is different. The SIM card here is inserted into a slot in the middle of one of the edges.
Apple's main priority is protecting the device and user data. The design of the smartphone protects it from any malicious attempts to steal user data and compromise the integrity of the device.
It is this method of fixing the SIM card, different from other smartphones, that protects it from unwanted penetration, and only the owner can do this. This also minimizes the likelihood of losing the SIM card even if the phone falls or receives mechanical damage.
Only in iPhone 3G and 3Gsm the slot for inserting a card is located at the top of the phone. At the same time, the iPhone 4 CDMA does not have a slot for installing a SIM card at all.
It is important to use only the SIM card tray that comes with the phone, since this part differs in different models, and trying to use the tray from the five to the seven can damage the device.
Interestingly, the new iPhone XS plans to use eSim, a new type that is a small chip (smaller than a nano-SIM) that is built into the device. It will save users from having to open the slot, and will also allow them to use another number without replacing the SIM card. The main catch is that the function is supported by the cellular operator.
Results and comments
Apple's key priority is the security of the device and user data. The design features described above make it difficult for malicious users to gain access to phone components. This technology gives developers hope that installing/removing a SIM card from a device will be under the control of the owner.
With such a locking mechanism, the SIM card does not fall out of the gadget and is not lost, even if the phone falls or receives other mechanical damage. In the case of iPhones, this tray arrangement was a distinctive feature of the company. No one has done this before.
How to put a SIM card in an iPhone
To access the slide on which the card is installed, use the special opening key located in the thick envelope.
Opening the slot
If there is no device, there is no need to panic; you can use a straightened ordinary paper clip or any other thin and long object, such as a needle, as a key. Don't be afraid of damaging your phone; if you act carefully, nothing will happen to it.
You should be wary of using fragile elements; they may remain inside the device, after which you cannot do without the help of a specialist to remove them. Try not to scratch the side of the smartphone.
The key for any model will fit all others. Therefore, even if the phone is broken, lost, stolen, etc., but you do not plan to stop using Apple smartphones in the future, you should not get rid of the key.
The paperclip is inserted into the hole without any effort; it just needs to be pushed in a little without tension. Be careful not to damage the tray.
It’s easy to open the slot and take it out from the inside of the slide, but if independent attempts do not yield results, you can contact the mobile operator’s showroom or the official Apple Store in your locality.
Installing a SIM card
After removing the tray from its slot, place it on a flat, horizontal surface for ease of installation. Please note that on iPhones the SIM card slot can be completely removed from the device, which means that when inserting it back you need to be careful so that the slide does not fall out or get lost.
Each SIM card has notches on one of the corners, which you need to navigate during installation. The notch in the slot will prevent the card from being installed incorrectly. The contacts (chip) should face down. You can return the tray to its original place in only one position; carefully push it in until it stops.
Turn on the smartphone
Then immediately hold down the power button to turn on the device. Although it is not necessary to turn off your iPhone to perform the procedure, it will be more convenient to do this with the device turned on. Usually the network is detected automatically, only in rare cases it is necessary to additionally activate the SIM card.
Interestingly, in the iPhone XS Max model, released specifically for the Chinese market, the slot is designed for 2 nano SIM cards at once.
What to do if the kit does not include a paperclip to open the tray
A common problem for Yabloko. Usually the factory key is lost during use. Most relevant for those who purchase a used, incomplete iPhone: the key is missing.
In this case, you need to use a homemade analogue of a standard tool. This may include:
- thin needle;
- paper clip.
Before use, the paper clip must be straightened and when installing the module, work with the sharp end. In this case, the diameter of the paper clip should fit into the tray cylinder. It's the same with the needle. At the same time, a handicraft tool should not be brittle, because a metal fragment stuck in the hole of the tray can lead to an expensive call to a specialized service.
Possible problems with reading SIM and ways to solve them
The SIM card does not always work correctly, even after successfully opening the device. In rare cases, users may encounter problems. To solve them, it is first necessary to determine the cause.
In some cases, to activate the SIM card, you will have to connect to the Internet via a wireless connection (Wi-Fi). If this is not possible, you can also connect your phone to i-Tunes using the included cable. The program automatically activates the card.
If everything worked, the screen will display the name of the cellular network and signal strength. If even after this the screen shows that “Network not detected,” it means that there are technical problems or the SIM card was inserted incorrectly.
Incorrect installation
Problems can arise if the SIM card tray is in the wrong position - skewed to the right or left. Or the card was inserted incorrectly. You will need to open the slot again.
If the problem arose due to unevenly installed slides, it will be enough to pull them out and insert them back, carefully locking them in the correct position.
When the SIM card is facing the wrong way (with the metal chip facing up or the notch on one of the corners does not match the shape of the slot), it will be enough to place the SIM card in the correct position.
If you cut the chip yourself, you may encounter the fact that there will be no serifs on it and you will get confused about which side it will be easy to install. To avoid this, make notes on the SIM card yourself, for example, using a marker.
Installation process
The general algorithm is shown using the example of the Apple iPhone 5S, but is also relevant for newer models):
- We take the device out of the case.
- We take out the SIM card connector key from the envelope - it has a large oval eye and is similar to a paper clip.
- We find the SIM slot on the right side panel of the iPhone or the top edge (the outline and lock cylinder are clearly visible).
- We insert the key into the hole, press lightly - access is open. On most devices, the holder with the SIM card pops out of the connector on its own. On used phones, the slide may be difficult to move due to wear or contamination.
