In the era of digital communication, anonymous calls and telephone spam have become a real problem for millions of smartphone owners. Every day, users are faced with intrusive offers of services, calls from debt collectors or attempts at fraud, which violate the comfort and safety of communication. The solution to this problem for subscribers of the largest Russian operator was specialized software that allows you to identify unknown numbers directly during an incoming call.
Service MTS Who is calling is an intelligent caller ID that works on the basis of a huge database updated in real time. Users of devices based on the operating system Android can access this protection tool completely free of charge using official distribution channels. However, the installation and configuration process has its own technical nuances that must be taken into account for the correct operation of the function of blocking unwanted contacts.
In this material we will analyze in detail the algorithm for installing the application, consider the features of its operation in the background and answer frequently asked questions that arise when using the software. You will learn how to correctly configure access rights so that the system does not “kill” the number identification process, and what opportunities are hidden behind the simple interface of the app.
Functional capabilities and operating principle of the ID number
The main task of the application is to instantly check the incoming number with a global database containing millions of records. When your smartphone receives a call from an unknown contact, the system analyzes the information in a split second and displays the name of the number owner, the name of the organization or the category of the call. This allows the user to make an informed decision: answer an important call from a courier or doctor, or ignore a suspicious call from an advertising agency.
In addition to simple identification, the software has a powerful traffic filtering mechanism. Machine learning algorithms analyze complaints from other users and behavioral patterns of callers, automatically marking numbers as “Spam”, “Scammers” or “Sales”. Automatic blocking Such contacts occur without the participation of the phone owner, which significantly reduces the level of stress and saves time.
Important It should be noted that the database is updated continuously thanks to the crowdsourcing mechanism. This means that if a new scammer number has been flagged by thousands of users in another region, your phone will receive this information almost instantly. Such collective protection creates a reliable barrier against modern telephone fraud schemes.
- 📞 Instant display of the caller's name even if there is no contact in the phone book.
- 🚫 Automatic blocking of numbers from the black list and spam categories.
- 🔍 Search for information by number manually through the built-in search string.
- 📊 Call statistics and a detailed log of incoming calls with notes.
⚠️ Attention: For the caller ID to work correctly, you must grant the application rights to process calls and access the phone. Without these permissions, the system will not be able to intercept the incoming signal and display information on the lock screen.
Where is it safe to download the application to your smartphone
The first and most important step is to select the source for downloading the installation file. In the environment Android there are many unofficial stores and sites offering modified versions of apps, but the use of such resources carries serious security risks. Downloading software from unverified sources can lead to infection of the device with malware, theft of personal data, or hidden subscription to paid services.
The only recommended way to obtain the application MTS Who's Calling is the official store Google Play Market. Here you can find a certified version of the app that has been checked for viruses and complies with Google security policies. Users just need to enter the name of the service in the store's search bar and click the install button.
For owners of Huawei and Honor smartphones that lack Google services, the situation may be different. In such cases, developers often offer to download the APK file directly from the operator’s official website or through the company’s application store AppGallery. When installing manually from a file .apk the system will ask for confirmation to install from unknown sources, which is a standard security procedure.
| Download source | Security level | Automatic updates | Recommendation |
|---|---|---|---|
| Google Play Market | High | Yes | Main option |
| MTS official website | High | No (manual) | For devices without Google |
| Third-party APK sites | Low | No | Not recommended |
| File sharing services | Critical | No | Forbidden |
Before installing any application, check the number of downloads and user reviews. Official applications of telecom operators usually have millions of downloads and high ratings.
Step-by-step guide for installation and initial setup
The process of installing the application on managed devices Android is standardized, but requires care at the stage of granting permissions. After downloading the installation package from the store, the system will automatically unpack the files and create a shortcut on the desktop. Launching the app for the first time initiates a setup wizard that will guide the user through all the necessary configuration steps.
The key point is to link the phone number. The application will ask for your number to log in to the system. This usually happens automatically through swiping the SIM card, but in some cases manual entry and confirmation via SMS codemay be required. Make sure that your smartphone has a SIM card from the MTS operator, since the service is optimized specifically for subscribers of this network, although number identification works for other operators as well.
Next follow the algorithm for granting access rights, which is critical for functionality:
☑️ Setting up rights access
1. Open your smartphone settings and find the “Applications” section.
2. In the list of installed apps, select MTS Who is calling.
3. Go to the “Permissions” item and activate access to Phone, Contacts and SMS.
4. Find the option “On top of other apps” and allow information to be displayed on the lock screen.
⚠️ Attention: Smartphone manufacturers (Xiaomi, Samsung, Huawei) often aggressively terminate background processes to save energy. It is necessary to add the application to the exceptions of the power saving mode, otherwise the detector will stop working a few hours after launch.
What to do if the application does not see the SIM card?
In rare cases, during manual installation, the system may not correctly read the SIM data. Try rebooting your device after installation. If the problem persists, enter your phone number manually in the authorization field and request a verification code. Make sure that the SIM card slot is active and has a network signal.
Setting up spam blocking and blacklist
After successful installation of the basic components, the stage of fine-tuning call filtering begins. The application interface provides flexible tools for managing which calls should be blocked and which should be allowed through. By default, a basic level of protection is activated, which filters out only the most obvious scammers, but the user can strengthen this barrier.
In the Call Blocking settings section, you will find toggles for different categories of unwanted callers. You can choose to block all numbers from the categories “Spam”, “Marketing”, “Collectors” or “Scammers”. The function of blocking hidden numbers is also available, although you should be careful with it so as not to miss important calls from medical or government agencies.
A separate module is provided for managing a personal list of unwanted contacts. You can manually add any number to Black List, and the system will automatically drop calls from this contact. In addition, there is a “White List” function, numbers from which will never be blocked, even if they are mistakenly marked by the system as spam.
- 🛡️ Setting the level of blocking aggressiveness: from a soft filter to complete isolation.
- 📝 Ability to add comments to blocked numbers for personal accounting.
- 🔔 Select the type of notification when blocking: vibration, sound signal or complete silence.
An interesting feature is the ability to configure a blocking schedule. For example, you can set a rule that all calls except contacts from the phone book will be blocked at night or on weekends. This provides a complete digital detox and guarantees uninterrupted relaxation.
Correctly setting blocking categories allows you to filter out up to 95% of unwanted calls, while maintaining access for important contacts from your records.
Solving common problems and conflicts
Despite the high stability of operation, users may encounter a situation where caller ID does not work or displays information with a delay. Most often, the reason lies in the limitations of the operating system Android, which in recent versions have become more strictly controlling the background activity of applications. If an application falls asleep, it cannot process an incoming call in a timely manner.
To solve this problem, you need to go to the battery settings of your device. Find the application in the list and set the operating mode to “No restrictions” or “Do not optimize.” On Xiaomi and Redmi smartphones, you also need to enable “Autostart” for the service in the corresponding security menu. This will tell the system not to forcefully terminate the process.
Another common problem is a conflict with other caller ID applications or built-in smartphone functions. Some manufacturers (for example, Yandex with Alice or built-in detectors in MIUI shells) may intercept calls first. In this case, it is recommended to disable the built-in detection functions in the phone settings, leaving only the application active MTS Who is calling.
⚠️ Attention: If, after updating the Android operating system, displaying the name on the screen stops working, check the “Display on top of other applications” permission. Often resetting security settings after an update disables this option by default.
If an application crashes on startup or does not work correctly, try clearing its cache through the app settings menu. If this does not help, perform a complete reinstallation of the software, first removing the old version. Make sure that your device has enough free RAM for stable operation of background services.
If you changed your tariff plan or telecom operator, do not forget to reassign the number in the application settings. This will ensure the correct operation of paid functions and synchronization with the database.
Questions and answers about using the service
Is the MTS Who Calls application free for all subscribers?
The basic functionality of the application, including number identification and basic anti-spam protection, is available to all users of Android smartphones for free. However, advanced features or the absence of advertising may be available to MTS subscribers, depending on the current tariff plan and current operator promotions.
Does caller ID work when roaming abroad?
The application continues to function in roaming, since number identification occurs on the server side or through a local database, and not through the voice channel. However, for the initial synchronization of the database and updates, an Internet connection (Wi-Fi or mobile data) is required.
Is it possible to use the application on a tablet without a SIM card?
Technically, you can install the application on the tablet, but its main functionality (detecting incoming calls) will not be available, since a tablet without a SIM card does not receive voice calls on the cellular network. The service is intended exclusively for voice communication via a mobile network.
Does the application affect battery consumption?
The application is optimized for minimal energy consumption. It is activated only when there is an incoming call or during a manual search. However, constant work in the background to monitor calls can slightly increase battery consumption, especially on older smartphone models.
How to remove your number from the ID database?
If your personal number is displayed to other users with an incorrect name or label, you can apply to edit the information through the feedback form in the application itself or on the official website of the service. Confirmation of ownership of the number will be required.
