Problems when the SMS center fails
The following guide is for those who don't know what to do if their Android device can't send or receive messages. Fixing this problem on a smartphone or tablet is simple, but to do this you need to follow certain steps sequentially. If you find that something is wrong with the SMS settings, most likely you need to change the server for outgoing and incoming messages.
Can the center number change without the user noticing? In fact, it is very simple to gain access to the message server, and this can easily be done by another person who briefly got into the hands of the phone
You need to be careful not to give your device to strangers, and also be careful about the settings and not make changes to parameters whose purpose is unclear
It is not recommended to trust the gadget to children, who may accidentally change the settings for receiving SMS. They may unwittingly set a different center number, causing the device to not process SMS.
The above problem can be fixed in a short time on any Android smartphone. After restoring the settings, you will be able to return to your correspondence. This process will be similar to deleting data using Factory Reset. To make sure the system is working, you will need to receive an SMS delivery report.
How to restore the functionality of the SMS center
The first thing you need to do is figure out why your custom message server failed. Its number is an attribute of the mobile operator, and all messages use this combination of numbers as a gateway for receiving and sending. Changing the numbers will result in the phone being unable to process the SMS and receive a delivery report.
The following guide will work for any Android device. In this case, the operating system version will not matter.
To configure the server, you need to perform the following steps:
- Call customer service and request the correct number. This is the only way, since only the operator knows this number. You can then enter the value manually.
- Open the application for sending messages on your smartphone.
- Go to the main menu, settings.
- Find the message center and select it.
- After entering the menu, enter the desired number.
- Make sure it is correct and click OK.
After this, the user will only have to send a message and receive a delivery report for the outgoing SMS to check whether the server is working.
How to find out the SMS center number
What an SMS center is and how to work with it is probably not known to everyone. Meanwhile, it is a point for exchanging letters between subscribers. On almost all SIM cards, regardless of the service provider and the current tariff plan, the service is configured automatically without the participation of the subscriber. But sometimes, when buying a new gadget or changing SIM cards, the settings can get lost. To make sure that the settings are saved in the smartphone without changes, it is recommended to perform the following manipulations:
- Turn on your mobile device.
- Open the “Settings” or “System Options” section.
- Go to the applications page and select “SMS/MMS”.
- When the message settings menu appears, select the “Advanced” tab.
- In the list of available options, find “SMS Center” and tap the button.
- The field that opens will contain the number that is relevant for the subscriber’s home region.
- The Message Type field is set to Text, Standard, or Normal.
- The data transmission channel is designated as “GSM”.
In some cases, users can easily receive text messages, but they cannot respond to them. To remedy the situation, you can try to select the SMS service center number manually. This identifier is stitched by the cellular operator on the SIM card. To access SMS center options you will need:
- Open the menu and go to the “Phone” section.
- In the input field, enter the service code *#*#4636#*#* (the combination may differ depending on the smartphone model and its class=”aligncenter” width=”1156″ height=”700″[/img]
- When the verification program window appears, select the “Phone Information” category.
- On the page that opens, scroll down the list of parameters and select “SMSC”.
By default, the phone number of the SMS service should be entered here. But if there is no information in this line or the message “Update error” is displayed, it means that it is not possible to access SMS. To solve the problem, you will need to manually enter the correct number and start the update process by touching the same key with your finger.
Finally, all that remains is to reboot the device and send a test notification.
How to set up SMS sending on Huawei and Honor?
To prepare your phone for sending and receiving messages, you should look at the settings section and set basic operating parameters. For this you will need:
- open the “messages” section using the corresponding icon;
- click on the icon with three dots and wait for the drop-down menu to appear;
- Tap the appropriate item and go to settings.
The most important thing is to indicate the SMS center. He is responsible for sending letters between subscribers. The SMS center number depends on the operator and is usually set automatically when you connect a SIM card. But, if this does not happen or the combinations are incorrect, users will have to make changes and configure the center manually.
Checking the functionality of the SIM card
Naturally, first of all, we check the availability of funds in the account necessary to send SMS. If there are enough of them, then it is advisable to move the card to another device and make sure that sending from it is possible.
If everything is fine, it is recommended to call the operator and find out if this function is disabled for the subscriber number. If not, make sure there is a network signal. Perhaps it is too weak or absent altogether. In this case, you will need to move to a place where the signal is better received and is stable.
Where is the SMS center on your phone?
This section can be found in general settings.
No connection for SMS exchange Honor/Huawei
If you find that there is no connection for exchanging Huawei SMS, then follow these steps:
- go to SMS settings;
- open the “SMS Message Center” section or find an item with a similar name;
- there will be a free field for entering a number, write there by hand +375297770000>;
- save changes.
Rolling back settings
This is the last correction option available to the user. You must first save all personal data. After this, proceed to the procedure for rolling back the parameter to its factory state:
- Turn off your smartphone completely.
- On the case we find the ON and “volume up” buttons. We clamp them. Hold until the recovery menu is activated;
- First, run “wipe data/factory reset” (mix the plus and minus of the sound, activate with the power button);
- Then, in the same way, activate the restart of the device – “reboot system now”.
As soon as the smartphone turns on, we check. If it doesn’t help, then you will have to go to the manufacturer’s branded service center to leave the mobile phone for diagnostics.
Method 4: Update
A phone is a small, compact computer with its own operating system. The OS, like any other program, can break down or be initially faulty. This often happens after a crooked update. But, as a rule, system developers quickly roll out a new update that fixes old bugs. There, in the “System” subsection, go to “Update”, check for the update and install it.
MTS SMS center: what is it, how does sending short messages work?
Let's start with the fact that the “SMS center” is a priori included in the standard set of any operator’s tariff plan. As a rule, the option to send short text messages (Short Message Service) is activated when the phone is connected, and the setup occurs automatically. But sometimes there are software failures and SMS messages do not go through. Next we will tell you what to do in such a situation.
To send messages, you need to support the functionality of your device and have it connected to your number. Everything is clear with the first point - nowadays it is difficult to find a mobile phone without the ability to send and receive SMS. Let's talk in more detail about the service itself, its configuration and the cost of connection.
How much does it cost to connect an SMS center number?
No payment is required for using and connecting to the service. Your correspondence is charged based on the terms of the connected plan. At the same time, all incoming messages are free.
If you are unable to send an SMS, contact the MTS hotline or any operator service center. You will be switched to a technical support specialist who will help you make the necessary settings. When visiting the office, take your passport with you.
Method 6: Cleaning the SIM card
Sometimes, after replacing the SIM card, SMS messages do not arrive due to poor contact with the phone. That is, you inserted a SIM, but it does not make good contact with the phone. At the same time, in the upper part you can see a complete lack of communication. There is a simple old-fashioned method that allows you to remove oxidation:
- Take out your SIM card.
- Take an eraser.
- Rub it over your SIM card contacts.
- Insert the SIM card back.
NOTE! If you don't have an eraser at home, you can use something metal, such as a needle or paperclip. Lightly scrape the contacts to slightly remove the top, oxidized layer. The most important thing is not to overdo it.
