Constant pop-up messages from the telecom operator often irritate users of smartphones based on Android. Whether it's intrusive advertising of new tariffs, balance reminders, or technical messages about connecting to the 4G network, these notifications interfere with the comfortable use of the device. Users Tele2 are no exception and are often faced with a flow of information that is difficult to control using standard methods.
The solution to this problem lies in an integrated approach, since messages can come from different sources: the SIM card itself, phone system services or proprietary operator applications. Understanding the nature of each notification allows you to effectively block unwanted notifications without losing important communication status information. In this article we will analyze all available methods for clearing the screen of excess information noise.
Analysis of Tele2 notification sources
Before you start blocking, you need to clearly determine where exactly the signal comes from. System messages Android about registration on the network and advertising SMS from the operator are fundamentally different types of data that require different processing methods. Incorrect setup may result in you not seeing important confirmation codes or balance information.
System notifications usually appear at the top of the screen and are associated with changes in the status of the radio module. For example, when switching between 3G and LTE networks, the phone may display a technical message. Advertising mailings come through USSD or SMS channels and are often disguised as system warnings. It is important to be able to distinguish them visually and by content.
To accurately diagnose the source of the message, pay attention to the icon in the status bar. If this is a standard message icon, then this is SMS. If a window pops up with the text of the server request or response, this is USSD request. Understanding this difference is critical to choosing the right blocking tool in your smartphone settings.
Disable promotional SMS and Push notifications
The most common source of irritation is advertising mailings. The operator Tele2, like others, uses communication channels to promote its services. Fortunately, modern versions Android and standard messaging applications allow you to effectively filter such content without requiring the installation of additional software.
The first step is to use built-in spam filters. Google's Messages app, which is installed on most modern smartphones, has an anti-spam feature. It automatically detects advertising mailings and places them in a separate folder, without disturbing the user with a sound signal or a pop-up window. This is the most secure methodas it does not disrupt the operation of the operator's main services.
☑️ Setting up message filtering
Additionally, you can block short numbers from which advertisements most often come. To do this, just open the unwanted message, click on the three dots in the menu and select “Block”. However, it is worth remembering that important service codes can also come from short numbers, so you need to block carefully, analyzing the contents of previous messages.
⚠️ Attention: Completely blocking all messages from short numbers may result in you not receiving a confirmation code to log into a bank or social network. Block only those numbers that are clearly sending advertisements.
Blocking pop-up USSD requests
Pop-up windows with the text of a request or server response (for example, “Your balance...") are often confused with system errors. In fact, this is the network's response to USSD requests. Some firmware Android (for example, MIUI from Xiaomi or EMUI from Huawei) have a built-in function for hiding such windows, but on “pure” Android (Pixel, Motorola, Nokia) it is often missing.
To solve the problem on standard Android you can use a special code to hide USSD responses. This method requires entering a command in the phone book. However, be careful: after entering the code, the phone may not show confirmation of canceling the subscription or changing the tariff, since the response window will be hidden.
##002#The above code is universal for canceling all forwardings, but to control the display of USSD windows on some devices (especially Samsung), codes like ##4636##, found in the testing menu, work. There, in the “Phone Information” section, you can find the “USSD strings” or “USSD replies” option, where the “No interaction” mode will hide the pop-up windows.
What to do if the codes do not work?
If standard codes do not help, try entering the code *155# and pressing the call button. In the menu that opens, try to find the “My Settings” or “Services” item, where you can sometimes disable newsletters. Installing a third-party USSD management application that intercepts network responses will also help.
Configuring system network notifications
System notifications about connecting to a 4G/LTE network or about signal loss are part of the operating system Android. They appear when the communication module is registered in the operator's network Tele2. It is difficult to remove them completely without root access, but you can make them less noticeable or turn off the sound.
To minimize discomfort, go to Settings → Applications → Show system processes. Find "Phone", "Google Play Services" or "SIM card" in the list (the name may vary depending on the model). Inside the Notifications section, find the category related to network or SIM card status and mute or hide the notification completely.
⚠️ Warning: Turning off system network notifications may result in you not noticing a complete signal loss or switch to roaming, which is fraught with unnecessary costs.
The path may differ on some devices. For example, on smartphones Samsung you need to go to Settings → Applications → (three dots) → Show system → SIM cards. Here you can configure in detail which events will be displayed in the status bar. This allows you to leave important warnings, but remove information noise.
Manage notifications in the My Tele2 application
The official operator application is a powerful source Push notifications. It informs you about the connection of packages, promotions and balance changes. If you use the application only to check balances, it is advisable to reconfigure its notifications, leaving only critical ones.
Go to the settings of the “My Tele2” application itself. Usually the section is located along the path Profile → Settings → Notifications. Here you can flexibly configure what you are informed about. It is recommended to leave only notifications about “Ending balance” and “Connecting services”, and turn off advertising mailings and news completely.
| Notification Type | Recommendation | Where to disable |
| :--- |--- | :--- |
| Promotions | Disable | In the “My Tele2” application |
| Tariff change | Leave | In the “My Tele2” application |
| Balance less than 30 rubles. | Leave | In the “My Tele2” application |
| Welcome messages | Disable | In the “My Tele2” application |
Do not delete the application completely if you need to quickly check your balance. It’s better to simply prevent it from showing notifications through the Android system settings: Settings → Applications → My Tele2 → Notifications → Turn everything off.
Using third-party applications for blocking
If the built-in tools Android are not enough, specialized applications come to the rescue. They allow you to create complex filtering rules for incoming messages and block USSD-answers. One of the popular solutions is the “USSD Controller” application or analogs available in Google Play.
Such apps work as an intermediary between the SIM card and the phone screen. They intercept the network response and, instead of showing it full screen, save it to a log or show it as a regular, non-intrusive notification. This is especially true for users who often use USSD codes to manage services.
⚠️ Attention: By granting a third-party application rights to work with your phone and SMS, you are trusting it with access to confidential information. Use only proven applications with high ratings and a large number of reviews.
When installing such software, carefully read the requested permissions. For the USSD blocker to work, the application will need rights to make calls and read the phone status. Without these rights, it will not be able to intercept system dialogs. After installation, be sure to test the operation by sending a balance request to make sure that the window no longer pops up on top of other applications.
Third-party USSD blockers are the most effective solution for “pure” Android, where there is no built-in option to hide server response pop-ups.
Hidden SIM card settings and cancellation codes for subscriptions
Sometimes notifications come due to activated paid or free subscriptions that the user might have forgotten about. The operator Tele2 provides universal codes for content management. Regularly checking active services helps get rid of the source of unnecessary messages and save money.
To view and disable all active subscriptions and services on the number Tele2 use the command *153#. This command will open a menu where you can see a list of connected options and unsubscribe from them. There is also a command *155*00#that allows you to manage basic service settings.
*153#Entering this command in the phone book and pressing the call button will launch the interactive menu. Follow the onscreen instructions to disable unnecessary services. This action can also reduce the number of service SMS reminding about tariff conditions or connected options.
Frequently asked questions (FAQ)
Why do notifications return after rebooting the phone?
This happens if you have disabled only the display, but not the service or subscription itself. System network notifications are part of the modem's operation and are restored every time you turn it on. For a permanent solution, you need to change the settings in the “Phone” menu or use third-party blockers that start automatically when the system starts.
Is it possible to completely disable balance notifications?
Yes, this can be done in the “My Tele2” application in the notification settings section. However, the system warning about a critically low balance (when the connection is about to be blocked) is more difficult to disable, since this is a function of the SIM card itself and the network, not the application.
Is it safe to use codes to hide USSD?
Using codes to change the USSD display is safe for the device, but can create inconvenience. You will simply stop seeing the server response (for example, “Service connected”). Always check your balance or service status in other ways after such changes.
Does blocking notifications affect Internet speed?
No, disabling visual notifications or SMS notifications does not affect data transfer speed or call quality in any way. This is an exclusively software configuration of the interface of your smartphone.
