At metro exits, train stations and shopping malls, you can often find promoters offering free SIM cards of different mobile operators. However, as cybersecurity expert Shamil Magomedov warns, using these SIM cards can be dangerous. According to Russian law, each SIM card must be registered with a specific person, including passport details. If you buy an unregistered SIM card, you may face legal problems and questions about the owner.
Also, the real owner of the SIM card can block it and try to restore it. This may result in loss of money in your mobile account and if you use this number for banking transactions, fraudsters can access your accounts. Therefore, using anonymous SIM cards for bank authorizations is also unsafe. Be careful and register SIM cards in your name to avoid potential problems.
