Subscribers of any cellular operator may encounter the problem of blocking the phone. If this happens, then during a call to the numbers sounds in automatic mode information that the phone number you have dialed is temporarily unavailable or blocked, and the text of this message is different. I have often faced such problems, and while solving the problem, I usually use a
phone number generator. First, it is very convenient because it is free for a certain period, and second, all the data is confidential.
