How to disable wiretapping on an MTS Android phone

The question of how to disable wiretapping on an MTS Android phone is becoming increasingly relevant in the era of digital threats. Users often confuse legal wiretapping by intelligence agencies, which cannot be legally disabled without changing the number, and malware installed by attackers or unscrupulous applications. It is the second type of threat that poses a real danger to your personal data, bank cards and correspondence.

The telecom operator MTS provides basic protection tools, but the main responsibility for security lies with the owner of the device. Smartphones based on Android have an open architecture, which makes them vulnerable to the introduction of Trojans, keyloggers and spyware. Understanding the mechanisms of operation of such threats is the first step to creating a reliable digital shield around your gadget.

In this article we will analyze technical methods for detecting hidden surveillance, check the settings of the device itself and consider operator services that may affect the privacy of calls. It is important to act consistently, without skipping a single step of the scan, to ensure that the system is completely cleared of outside interference.

Device diagnostics: signs of spyware

The first stage in the fight against unauthorized access is to identify symptoms of infection. Malicious apps that intercept audio or data consume system resources, which inevitably affects the operation of the smartphone. If you notice that the battery is draining significantly faster than usual, even in standby mode, this is an alarming sign.

Pay attention to the heating of the case. Background recording Sound or real-time data transfer puts a high load on the processor. The phone may become hot without active user interaction, for example, during a conversation or browsing simple pages in the browser.

⚠️ Warning: A sudden increase in Internet traffic consumption without changing your usage habits may indicate that the application is secretly sending recorded files to a remote server.

Also worth it listen to the quality of communication. Extraneous noises, clicks, echoes, or delays during a call may indicate interference with the audio channel. Although some interference is caused by a poor network signal MTS, their regular occurrence in areas of good reception requires checking.

Checking phone settings and special features

Most modern spyware requires advanced access rights for the user to operate often provided by chance. A critical section is the accessibility menu, where malicious code can take control of the screen and text input.

You need to carefully check the list of installed applications. Attackers often disguise spyware as system services or apps with neutral names such as "Update Service" or "System Helper." Suspicious software should be removed immediately after detection.

• 🔍 Go to Settings and find the section Accessibility (Accessibility). Review the list of active services and disable all unknown ones.
• 📱 Check the section Device administrators in the security settings. Malware often sticks here so that it cannot be removed in the usual way.
• 🚫 Review application permissions, especially access to the microphone and camera. Revoke rights from apps that do not need them to work.

If you find an application that is not uninstalled or the uninstall button is inactive, then it has administrator rights. First disable these rights in the appropriate menu, and then uninstall. Ignoring this step will make it impossible to completely remove the threat.

Using MTS engineering codes and USSD commands

You can use special codes to quickly check the forwarding status and other network settings. These commands allow you to see where your calls are being redirected, which is a common method of intercepting information without installing software on your phone.

Enter the code in the dialer *#21# and press the call button. The status of all types of forwarding will be displayed on the screen. If you see an unknown number other than your voicemail, this is a sign that calls may be forwarded to third parties.

*#21# - Check forwarding status
##002# - Cancel all forwards
*#62# - Check forwarding when unavailable

The command ##002# is a universal tool for resetting all forwarding settings on the operator's side MTS. This action is safe and free of charge; it returns the network settings to factory defaults, blocking potential call interception channels.

In addition to codes, there are services from the operator itself. Make sure that your number is not connected to paid wiretapping or location services, which could be activated by scammers through social engineering. You can check the list of active options in your personal account or through the app My MTS.

Scanning the system with anti-virus utilities

Manual scanning is not always effective against complex threats that use hiding methods (rootkit). For in-depth analysis of the file system, it is recommended to use specialized software. There are many solutions on the market that are adapted to the architecture. Choose antiviruses from well-known vendors, such as Android.

Choose antiviruses from well-known vendors such as Kaspersky, Dr.Web or ESET. Free versions often have sufficient functionality for a one-time scan and removal of detected threats. Avoid dubious applications from unverified sources, as they themselves may contain malicious code.

Antivirus name	Scan type	Real-time protection	Features
Kaspersky Internet Security	Deep	Yes	Anti-phishing, call blocking
Dr.Web Light	Fast/Full	Optional	Effective against ransomware Trojans
ESET Mobile Security	Intelligent	Yes	Search for a stolen device, security audit
Malwarebytes	Pointed	No (free)	Specialization in removing already installed threats

After installation, update the signature databases and run a full system scan. This process may take from 10 to 30 minutes depending on the amount of memory and the number of installed applications. Do not interrupt the scan to ensure a thorough analysis of all memory sectors.

Radical measures: resetting to factory settings

If software methods did not help resolve the problem and suspicions of wiretapping persist, the only guaranteed solution is to completely reset the device. This procedure removes all data, applications and settings, returning the phone to its original state.

Before performing a reset, it is critical to back up your personal data: contacts, photos and documents. However, do not restore your application backup immediately after resetting, as you risk returning the infected file back to a clean system.

⚠️ Warning: Resetting your settings will delete all data from the phone's internal memory. Make sure that you have saved important files to your computer or cloud storage before starting the procedure.

To perform a reset, go to the menu Settings, select the section System or General settings, and find the item Reset settings. Confirm the action by entering your PIN code or unlock pattern. The device will reboot and begin the cleaning process, which will take a few minutes.

What to do after the reset?

After returning to factory settings, do not install all applications at once. Start with a basic set (messengers, banking) and observe the behavior of the system for a couple of days. If the problem does not return, you can gradually add the rest of the software, downloading it only from the official Google Play store.

After switching on, the phone will be like new. You'll need to re-set up your Google account, connect to Wi-Fi, and install the necessary apps. This is the most reliable way to get rid of any hidden threats, including those that have received root access.

Prevention and rules of digital hygiene

Eliminating the current problem is only half the battle. To ensure that the question “how to disable wiretapping on an MTS Android phone” no longer bothers you in the future, you must follow the rules of digital security. Prevention is always more effective and cheaper than treating an infected system.

Never install applications from third-party sources. In your settings, disable the ability to install APK files from unknown sources. Download software exclusively from the official store Google Play, where apps are tested for security.

• 🔒 Regularly update the operating system and installed applications. Updates often contain patches to close security vulnerabilities.
• 📵 Do not connect to open and unsecured Wi-Fi networks in public places to enter sensitive data.
• 👀 Keep an eye on the microphone and camera usage indicator that has appeared in new versions of Android. If it lights up without your will, this is an alarm.

Use strong passwords and two-factor authentication for all important accounts. Even if an attacker gains access to your device, the additional layers of protection will make it more difficult for someone to steal your data. Remember that your vigilance is the main factor of protection.

Can the MTS operator himself listen to my conversations?

The telecom operator technically has access to the data stream, but wiretapping of conversations without court approval is illegal. Usually, by “MTS wiretapping”, users understand services like “Parental Control” or “Caller ID”, which require your consent or the consent of the owner of the number to connect.

Will changing the SIM card help against wiretapping?

No, changing the SIM card will not remove the spy application installed in the phone’s memory. The malware will continue to work and transfer data even if you insert a new SIM card from another operator. It is necessary to clean the device itself.

How to find out who installed the spyware?

It is impossible to find out the identity of the attacker through the phone settings. Antiviruses can show the name of the threat, but not the author. If you suspect a criminal offense, you need to contact the police to have the device examined by specialists.

Is it safe to use codes like *#21#?

Yes, using USSD codes to check forwarding settings is absolutely safe and free. These commands are standard for GSM networks and cannot harm your phone or account.

What to do if the phone requires superuser rights (Root)?

If an application requests root access, and you are not planning a deep modification of the system, immediately deny access and delete this application. Granting such rights gives the app complete control over the device, which is critically dangerous.
