My wife met a man on the Internet. He does not make secrets from this. It exchanges SMSs of completely innocent content that cancellation did not hide. But it was alarming that the man gave Vimpel (Beeline) mobile number of St. Petersburg, to which his wife sends messages, and the recipients come from another Vimpel (Beeline) Moscow number. Although the man claims that he has no relation to Moscow. Once called from a city number of St. Petersburg. I struck the number on my channels, but it did not work much. Plus, the arrival of an SMS-ok began with an interval of about an hour from the MTS Moscow number, which, according to the wife, she does not receive. Of course, you can simply change the number of her mobile phone. But I want to understand the situation. Can you help something?
