Many users want to protect their personal data. Therefore, they put a password on the smartphone.

Subscribers are increasingly turning to service centers and customer service offices with the question of how to unlock an MTS phone. In this case, blocking can arise for various reasons, therefore, this problem has several solutions. The blockage can be removed entirely in almost any situation.
It is necessary to make a start in solving the problem of unlocking the MTS phone from the reason for the appearance of the block. If it is associated with the smartphone itself, which stopped working due to an incorrectly entered software password, this can only be eliminated by reflashing and other special methods offered by modern service centers. If the block arose as a result of an incorrect PIN or PUK code, you will need to replace the SIM card with a new one at the sales office.
There is also a third type of blocking - binding a smartphone to one operator. It is also possible to remove it with certain skills, but this is much more difficult to do.
How to unlock an MTS phone if you forgot your password
In this case, it all depends on what kind of digital code was forgotten or lost. When selling, two basic passwords are tied to a SIM card: PIN and PUK. If you enter the PIN incorrectly three times in a row, it will be blocked and then the phone will start asking for the PUK. The latter can be entered for ten times, after which the SIM card will be completely blocked. To avoid this, you must always keep the contract for the sale of the card at hand or memorize the number combination by heart.
Even if the PIN and PUK were entered incorrectly and the card was completely blocked, it is possible to restore it with the same number, balance, tariff plan and a set of options. To do this, you will need to contact the MTS sales office with a passport and an old card and explain the current situation. The replacement will be made on the same day.
How to unlock an MTS phone if you forgot your graphic password

How to unlock a phone from MTS for other operators
