The SIM is locked, and you have to enter your PUK code to unlock it. You'll need to get your PUK code from your carrier, but sometimes the PUK code is in the documentation that comes with a SIM, especially if it's a pre-paid SIM.

 

In my experience, a carrier will/can not give a PUK code.

I went through this years ago, and if you enter the wrong code a number of times, the card will be locked- with a PUK2 code.

Good luck getting either one.

Best bet is to tell your carrier what happened, and they will {should} issue you a new card.

 

Did you get any documentation with the SIM card when it was issued? Unfortunately I can't really help you as I'm not in the US, and have never had to deal with their carriers or whatever MVNOs.

But FWIW I'm in China and when I've obtained any SIMs here, the PUK/PUK2 codes are on scratchcards that come with the SIMs.

 

i would call att first and then work your way down the list. one of them should help you out.

 

Yes and that is what I used to copy the puk exactly several times but it says it's incorrect.

 

OK, you definitely need to obtain a replacement SIM then, either from "at&t, tracfone or safelink", whichever one is your front-line service provider.
