Facing intrusive calls from scammers, spammers, or simply unwanted interlocutors is one of the most pressing problems of a modern smartphone user. This issue is especially relevant for subscribers MTSwho often face aggressive telemarketing or attempts to deceive. When your phone is buzzing with constant notifications and unnecessary messages are piling up in your memory, there is a natural desire to completely isolate yourself from a specific source of irritation. Fortunately, the ecosystem Android in conjunction with the operator's tools provides powerful tools for solving this problem.
In this article we will look in detail at how to block a phone number so that they do not call or write SMS to MTS on Android, using both the built-in functions of the operating system and the specialized services of the operator. You will learn the difference between blocking at the device level and at the network level, as well as what nuances should be taken into account when setting up a “black list” on various smartphone models. Properly setting up protection will allow you to regain control of your time and nerves, turning your gadget into a communication tool rather than a source of stress.
Built-in blocking capabilities in Android
The first and most accessible method of protection is to use the native functionality of your operating system. Most modern smartphones based on Android (version 9 and higher) have a built-in call filtering mechanism that works locally on the device. This means that blocking occurs directly on the phone, and the telecom operator MTS in this process acts only as a traffic provider, without interfering with the sorting of incoming signals. To activate this feature, you usually just need to go to the Phone application and select the desired contact or number from your call history.
After selecting a number in the action menu, the “Block” option or the crossed out circle icon often appears. However, the interface may differ depending on the manufacturer of your device. For example, on pure Android (Google Pixel, Motorola) the path lies through the call settings, while in shells MIUI (Xiaomi) or One UI (Samsung) these functions are placed in separate security or antispam sections. It is important to understand that standard blocking on Android most often simply drops the call or sends it to voicemail, but the subscriber can still hear beeps before the connection is interrupted.
As for text messages, the situation here is a little more complicated. In the standard Google Messages application, the blocking function works effectively: emails from blocked contacts are simply not displayed in the general list, but are moved to a separate Spam and Blocked folder. This allows you not to miss an important notification if the number was blocked by mistake, but at the same time eliminates the constant visual noise. For complete silence, you need to set up notifications so that the arrival of messages from this folder is not accompanied by sound or vibration.
- 📱 On the clean Android go to the “Phone” application → three dots → “Settings” → “Blocked numbers.”
- 🛡️ On smartphones Samsung use the built-in Smart Call app to automatically detect and block spam.
- 📩 In the Messages app, check your privacy settings to hide the contents of notifications from unknown senders.
⚠️ Attention: Built-in blocking at the phone level is not 100% guaranteed. silence during calls. The caller can still reach you (see the dial tone), but your phone simply won't ring. For complete invisibility, operator services are required.
Blocking services from the MTS operator
If the built-in tools of your smartphone seem not reliable enough for you, you should turn to the tools provided by the telecom operator itself. MTS offers a number of paid and shareware services that filter traffic even before it reaches your device. This is a fundamentally different level of protection: the call is interrupted on the network side, and your phone does not receive a signal at all about the incoming connection. For subscribers who are being pursued by collectors or aggressive marketers, this is the only effective solution to keep the number secret from specific individuals.
One of the most popular services is the “Black List” from MTS. It allows you to enter up to 300 numbers into the blocking database on the operator’s side. Activating the service usually costs a small monthly fee (about 1-2 rubles per day, depending on the tariff), but it provides a guarantee that the blocked subscriber will not be able to reach you either through calls or via SMS. When you try to dial, Caller will hear a busy signal or an unavailable message, while you will not even know that a connection attempt has occurred. The list can be managed through your personal account, the My MTS mobile application or USSD commands.
In addition to manually adding numbers, MTS offers the Antispam service, which uses a large database of known scammers and advertising agencies. This function works automatically, identifying suspicious numbers and blocking them or marking them in a special way on the screen of your smartphone. The combination of manual blocking of specific abusers and an automatic spam filter creates the most effective shield for your digital space. It is important to note that some anti-virus functions may be enabled by default in new tariff plans, so it is worth checking your personal account before connecting additional options.
| Name of service | Cost | Opportunities | Connection method |
|---|---|---|---|
| Black list | ~1.5 rub/day | Blocking up to 300 numbers | USSD *111*442# |
| Antispam | Free / Paid | Filtering known spammers | My MTS application |
| Parental control | ~3 rubles/day | Limiting contacts for children | Personal account |
| Caller ID | ~2 rubles/day | Identification of unknown persons | USSD *111*0161# |
⚠️ Attention: Tariff conditions and names of operator services MTS may change. Before connecting, be sure to check the current prices in the official My MTS application or on the operator’s website to avoid unexpected charges.
☑️ Preparing to connect MTS services
Using third-party applications for filtering
When the capabilities of the system and operator are not enough, specialized applications from the store come to the rescue Google Play. These apps use their own global databases that are updated in real time by a community of users. The leaders in this niche are Kaspersky Who Calls, Truecaller i Yandex.Identifier. Their main advantage is the ability to identify a number even before you pick up the phone, showing on the screen the name of the organization or the mark “Spam”, “Fraud”, “Real Estate Sale”.
Installation of such software requires broad permissions to access contacts and call logs, which raises questions among some users regarding privacy. However, the effectiveness of these apps often outweighs the risks, especially if you receive dozens of calls a day. After installation, the application automatically scans incoming traffic and, when it detects a number in the “black list” of the database, either drops the call or sends it to a special section, without disturbing you with a sound signal. Some applications can also filter SMS, hiding messages with advertising links or phishing content.
It is important to correctly configure filtering rules in a third-party application so as not to miss an important call from a courier or doctor who may be calling from an unknown number. It is recommended to set the protection level to “Medium” or manually confirm blocking of questionable numbers in the first days of use. It is also worth regularly updating the application databases, since scammers constantly change numbers, and yesterday’s “clean” number may already be listed in the spammers database today. Integration of such applications with system dialing on Android usually occurs seamlessly, replacing the standard calling interface with your own.
- 📥 Download the application Truecaller or Kaspersky Who Calls from the official Google Play store.
- ⚙️ Grant the application rights to access your phone and contacts for the database to work correctly.
- 🔇 In the application settings, activate the “Automatic spam blocking” function and select the desired level of severity.
How do identification databases work?
The application downloads a compressed database of known spam numbers to your phone. When a call comes in, the number is checked against this database locally. If a match is found, the call is blocked. For unknown numbers, cloud verification can be used, which requires the Internet.
Blocking via Do Not Disturb mode
Sometimes you need not just to block one specific number, but to protect yourself from all calls and notifications for a certain time, leaving the possibility of communication only for selected contacts. For these purposes, Android there is a mode “Do not disturb” (Do Not Disturb). This is a powerful tool that allows you to create a whitelist of allowed numbers, while all other calls and messages will be ignored by the system. Unlike the blacklist, here you block the whole world, except those who are really important to you.
You can set up this mode in the “Sound and vibration” section of your smartphone’s settings. You can set a schedule to turn on (for example, during sleep or work) or activate it manually. A key feature is the ability to allow repeat calls: if the same number rings twice within 15 minutes, the phone will skip the call, treating it as an emergency. This is a useful feature that prevents you from missing really important news if the person you need has forgotten that you have turned on silent mode. Messages from blocked contacts in this mode will not make sounds and will not appear on the lock screen.
Do Not Disturb mode is especially effective when combined with operator-level blocking. While MTS filters out obvious aggressors, the system mode hides the rest of the information noise. However, it is worth remembering that when Do Not Disturb mode is active, alarms usually continue to work, but notifications from instant messengers (WhatsApp, Telegram) may be hidden if you do not add these applications to the exception list. Fine-tuning the settings allows you to achieve the perfect balance between accessibility and privacy.
⚠️ Attention: In Do Not Disturb mode, you can miss calls from delivery services or taxis if their numbers are not saved in your contacts. Always check the list of exceptions before activating the full silent mode.
Add a “Family” or “Work” contact to the exceptions of the “Do Not Disturb” mode so that your loved ones can reach you even when the phone is in complete isolation from the rest of the world.
Features of blocking SMS and MMS messages
Blocking text messages is often more difficult than filtering calls, since the protocol SMS is less interactive. If the call can simply not be accepted, then the message has already been delivered to the device at the time of receipt. The Android solution to this problem lies in setting up the messaging application. The standard Google Messages application has a built-in smart filter that automatically detects spam and moves such messages to a separate folder without notifying the user.
For more stringent blocking, when you need to completely ignore messages from a specific number, you can use the contact blocking function. In this case, messages from the sender will not appear in the main chat feed. However, depending on the version Android and firmware, they can either be deleted forever or stored in a hidden archive. It is recommended to periodically check the Spam folder to make sure that important confirmation codes from banks or services that could be mistakenly classified by the system as unwanted do not end up there.
If you use services MTS to block, then the operator can intercept and SMS from blacklisted numbers. In this case, the message will not reach your phone at all, which saves memory space and eliminates the need for manual cleaning. However, it is worth considering that short service messages from the operator or banks themselves can sometimes bypass filters, since they come from special service gateways and not from regular mobile numbers. To combat advertising mailings from services, it is better to use the unsubscribe command, usually indicated at the end of the message.
- 🗑️ Regularly empty the "Spam" folder in the message application to free up space and check for the absence of false positives.
- 📵 To completely block, use combination: phone blacklist + “Black List” service from MTS.
- 📢 Use the “STOP” or “Unsubscribe” command for legal advertising mailings to stop the flow of messages in a legal way.
A comprehensive approach to blocking SMS includes setting up filters in the message application and connecting operator network services to intercept traffic at an early stage.
What to do if blocking does not work
There are situations when, despite all the measures taken, unwanted calls or messages continue to arrive. This may be due to the fact that spammers use number substitution technologies (spoofing), each time calling from a new digital identifier. In this case, blocking a specific number becomes a meaningless game of cat and mouse. The solution lies in activating the most strict filters in identification applications that block not specific numbers, but entire categories of numbers, for example, all hidden numbers or numbers from certain regions.
Another reason for the ineffectiveness of blocking may be failures in synchronization between the phone and the operator’s servers. If you have added a number to the blacklist through the My MTS application, but calls continue, try repeating the action via the USSD command or rebooting your smartphone. Sometimes it takes time (up to 24 hours) to update the databases on the network side. Also make sure that your paid service has not expired or you have not had problems paying your personal bill, which could lead to automatic disabling of protection options.
In extreme cases, when the harassment becomes intrusive and threatening, it makes sense to contact law enforcement agencies. MTS can provide call details and information about the owner of the number (at the request of the police), which will help bring the offenders to responsibility. For ordinary users, the most effective method remains to constantly update the spam databases in security applications and use the Antispam mode with a high level of sensitivity. Do not forget that security in the digital environment is an ongoing process that requires attention to the settings of your device.
Is it possible to block a number if it is hidden (the identifier is prohibited)?
It is impossible to block a specific hidden number, since you do not know its digital value. However, in the smartphone settings or through the operator’s services, you can enable the “Block all hidden numbers” function. In this case, any calls where the subscriber has hidden his ID will simply not get through to you.
Will the blocked subscriber see that I blocked him?
The subscriber will not receive a direct notification about the blocking. When calling, he will hear long beeps (if the lock is on the phone) or a busy/unavailable signal (if the lock is via MTS). This may lead him to think about blocking, but technically the system does not report this fact.
Will SMS from a blocked number be received on MTS?
If you use the “Black List” service from the MTS operator, then SMS from blocked numbers will also not be delivered to your device. If you only used blocking on your phone, messages may arrive, but will be hidden in the spam folder or will not trigger notifications.
How many numbers can you add to the blacklist on Android?
The built-in blacklist in Android usually does not have a strict limit on the number of numbers, limited only by the amount of device memory. However, operator services (for example, MTS) often have a limit, for example, up to 300 numbers for a standard service tariff.
Is it possible to recover messages from a blocked contact?
If messages were deleted automatically or were not saved in the Spam folder, they cannot be restored. If they have been moved to the spam archive (in the Google Messages application), you can go to this folder, open the message and return it to the main chat list.
