Blackberry Priv at & t really need help! | After unlocking you are asked to enter the PUK code
Hello everyone, I am new here, so please do not kick, I did not find anything similar to my regret. So actually the problem: I bought a blackberry priv 100-1 on ebay, the phone was locked to the at & t operator, I requested an unlock, the operator sent me a code, after I entered the unlock code, the phone asks me to enter some PUK code and Writes sim / ruim blocked by Perso, the PUK code from my sim does not fit, and she does not ask for any codes when inserting a SIM card into another phone. I tried to contact the seller, he wrote to me that I incorrectly enter the PUK code from my SIM card, in general, he is a fool. Help me please, advise any ways to solve this problem. Thank.
