Checking your mobile phone for wiretapping and surveillance is not that difficult.
We'll tell you what you need to do for this.
How to find out if your phone is being tapped
To check your phone for wiretapping, you need to find out if calls are being forwarded.
This can be done using USSD commands. First, dial *#21#.
You will receive a notification about whether the forwarding is active. If it is active, dial *#62#.
The numbers to which the call is being forwarded will be displayed. Even if only one number is displayed, it is better to check it on the network.
This may be a voicemail number. In this case, everything is fine, your calls are not going to strangers.
If the number/numbers are not associated with a voicemail service, call forwarding must be disabled.
We go to the settings, find the program “Phone” (“Calls”) through “System applications” and in the “Call forwarding” section we disable all unnecessary (not related to operator services) numbers.
As for tracking, you need to open “Applications” in the settings and delete all suspicious ones.
