    Hello Gurus,

    I bought an unlocked AT&T Lumia 900 yesterday. As I inserted my non AT&T SIM, it prompted me for the SIM PIN code. I tried all the possible combinations and exhausted 10 SIM unlock and 32 PUK attempts. Since then the phone is not accepting any SIM card. It displays SIM Error message. Is there any way I can get my Lumia to work?
    Please help.
    Thanks
    Iceman

    I believe it is not unlocked. I bought an unlocked 900 and I put my Tmobile Sim and everything worked without any problem. I could only get the speed to be Edge though due to the band difference. But the phone is locked. You should have contacted the seller before you put in the code.

    Thanks Michael for the quick response. So now, what are my options? Is the phone useless now?
