Owners of smartphones based Android sometimes face a situation where messages from the operator Tele2 do not arrive or are not sent to subscribers. This may be due to incorrect message center settings, problems with the APN access point profile, or even simple software errors in the device itself. Fortunately, in most cases, the problem can be solved manually in a few minutes without the need to contact a service center.
Correct configuration of network parameters is the key to stable operation mobile communications. The Tele2 operator uses standard protocols, but automatic setup does not always work perfectly, especially after changing the SIM card or updating the operating system. In this article we will look in detail at how to check and change the settings SMS center, as well as what to do if messages are blocked by the system.
Automatic configuration of network parameters
The easiest way get the latest settings - request them from the operator. Tele2 automatically sends a configuration file when you first connect a new SIM card, but this process can be initiated again. To do this, just send a free USSD request or call the support service, after which a special message with parameters will be sent to your phone.
After receipt configuration message you need to open it and click the “Install” or “Save” button. The Android system will ask for confirmation to change the network settings - agree. It is important not to delete this message until the installation is complete, as it contains encrypted data for the profile APN and message center.
Sometimes automatic installation requires a reboot of the device for the changes to take effect. If after rebooting the messages still do not work, proceed to manually checking the settings. It is also worth making sure that there are funds on your balance if you plan to send paid messages, although incoming messages from the operator are always free.
- 📲 Send a USSD request
*105#to call the settings menu. - 📩 Wait for the incoming SMS with parameters from Tele2.
- ⚙️ Click "Save" and enter the PIN code if the system asks for it (usually 1234 or 0000).
- 🔄 Reboot your smartphone to apply the changes.
Manual setup of the message center (SMSC)
If the automatic method did not help, you need to manually check address message center. This is the operator's server through which all your text messages pass. Incorrect SMSC number is the most common cause of sending errors. On Android smartphones, this option is hidden in the settings of the Messages application or in the engineering menu.
To find the desired section, open the standard SMS application, click on the three dots in the corner of the screen and select “Settings”. Next, go to the “Advanced” or “SIM Card Settings” section. Here you will see a field Message Center or SMSC. For the Tele2 network, the number must be strictly defined; any deviations will lead to failure.
Enter the following number in the message center field: +79220000050. Please note the format: the number must begin with a plus. After entering, click “Save” or “Install”. In some phone models, for example Samsung or Xiaomi, the path to this setting may be slightly different, but the essence remains the same.
⚠️ Attention: If the field for entering the message center number is inactive (locked), try removing the SIM card, inserting it again and restarting the phone. Sometimes the interface is blocked due to a temporary failure to read the card.
Before changing the message center number, write down the old value. If the new settings do not work, you can easily return to the original settings.
Checking and editing the APN access point
Although the access point APN is primarily responsible for the mobile data, its incorrect operation can affect the message delivery service (MMS) and the status of SMS read reports. The Tele2 operator uses συγκεκρι parameters to identify traffic on its network. Checking these settings is a mandatory step in complex diagnostics.
Go to Settings → Connections → Mobile networks → Access points (APN). If the list is empty or the settings differ from the recommended ones, create a new access point. Click the plus or add icon at the top of the screen. In the menu that opens, you need to fill in several fields, the rest can be left unchanged.
The key parameters are “Name” and “APN”. Enter tele2in the name field, and internet.tele2.ruin the APN field. The authentication type must be set to PAP or CHAP, and the APN type to default,supl. After filling out, save the profile by clicking on the three dots and selecting “Save”, then activate it by placing a dot next to the name.
| Parameter | Value for Tele2 | Required |
|---|---|---|
| Name | tele2 | Yes |
| Access point (APN) | internet.tele2.ru | Yes |
| Proxy | Not specified | No |
| Port | Not specified | No |
| Authentication type | PAP or CHAP | Recommended |
☑️ Checking APN settings
Fixing problems with sending messages
Even with the correct settings, situations may arise when messages “hang” in the “Sending” status. This is often due to application memory being full or a cache conflict. Clearing the message service cache is a safe procedure that will not delete your correspondence, but can restore the functionality of the function.
Go to Settings → Applications → Messages. Select "Storage" or "Memory". Click the button Clear cache. Do not confuse this button with the “Clear Data” function, as the latter can delete your chat history if it is not synchronized with the cloud. After cleaning, try sending a test message.
Another reason for failures may be the power saving mode. Aggressive battery settings in modern Android skins (for example, MIUI or OneUI) can “kill” the background processes of the SMS service. Add the Messages app to exceptions or allow it to run in the background in your battery settings.
⚠️ Attention: If you're using a third-party SMS app (like Textra or Google Messages), make sure it's set as your default app. A conflict between two active messaging applications is not possible.
Why don’t messages go through when the signal is full?
Sometimes the problem lies not in the signal, but in the congestion of the communication channel in your area. Try turning Airplane Mode on and off to force re-registration on the network.
Setting up MMS and multimedia messages
Sending pictures and videos via MMS requires an active mobile data, even if you have an unlimited tariff. Unlike regular SMS, MMS use a data transfer protocol. If the Internet is disconnected or configured incorrectly, the multimedia message will not be uploaded to the operator’s server for sending.
Make sure that the correct APN and port are specified in the APN access point settings (discussed above), if required by your phone model. For Tele2, the correct APN is usually sufficient, but in older models you may need to specify MMSC: MMS proxy and port, if required by your phone model. For Tele2, the correct APN is usually sufficient, but in older models you may need to specify the MMSC: http://mmsc.tele2.ru. Without this setting, the phone will not know where to send the media file.
Also check the size of the attachment. Operators often limit the maximum size of one MMS (usually up to 300-500 KB). If you are trying to send a high-resolution original photo, the system may automatically reject the transaction. Try compressing the image before sending or changing the quality settings in the messages application.
MMS do not work without mobile data. Make sure that data transfer is turned on, even if you are within Wi-Fi coverage.
Spam blocking and message filtering
Modern smartphones are equipped with powerful spam filters that can mistakenly classify important notifications from Tele2 (for example, verification codes or balance information) as unwanted. These messages often end up in a separate Spam or Blocked folder without sounding a notification.
Check the spam folder in your messaging app regularly. If you find a useful message from an operator there, mark it as “Not spam” or add the sender’s number to the white list. In the anti-spam settings, you can disable filtering for short numbers that are usually used by telecom operators.
In addition, some antivirus applications have their own SMS filtering modules. If you have a third-party antivirus installed, go to its settings and check the “Anti-spam” section. Perhaps it is the one that blocks incoming messages from the service Tele2.
- 🛡️ Open the “Messages” application and find the “Spam” folder.
- ✅ Add Tele2 short numbers to your contacts or white list.
- 📵 Check the settings of third-party antiviruses for blocking SMS.
⚠️ Attention: The settings interface and menu item names may differ depending on the version of Android and the model of your smartphone (Samsung, Xiaomi, Honor, etc.). If you do not find an exact match, look for sections with similar meaning.
