Unlocking a Samsung Galaxy S7 Active
I have a samsung galaxy s7 active that I submitted an unlock request for. The directions indicated I should shut off the phone, remove the sim card, turn it on and enter the code. It didn't specify where. I followed the directions, entered the code in the dial pad and I got a message saying only emergency calls were allowed. Did the same thing again, this time inserting an inactive tracfone sim card. Got the same message. Although when I turned on the phone I got the message "SIM not provisioned MM#2".
Does this mean that the phone was/is already unlocked? I tried calling AT&T, I don't have active AT&T service and they weren't any help accept to send me another unlock code (which was the same as the first unlock code I received). Can anyone advise?
