Gentlemen, they are scammers, they will not unlock anything for you, I sent them my phone to unlock, which is not tied anywhere and is in a clean list, they took money and then asked for more, and then said that it was blocked by the operator and in the black list. After they asked for a premium service pay. As a result, the amount is equal to the purchase of another phone, I did not believe them and did not pay. On another site I was unblocked it without problems and 3 times cheaper. DO NOT BUY ANYTHING FROM THEM, THIS IS FRAUDERS!
