    Go to carrier select by country and carrier then put the cable in itunes. It will give you an error , it’s normal, than you should see the signal

  • Nunod75

    BIG PROBLEMMMM: it says Activation reports Error: Activationinfo rejected. you must select the original carrier SIMID of your phone…

    HELP ME PLEASE

  • Francis

    What if, if I just have one sim? How should I do it?

  • Kelshamaa

    there is no carrier option

  • Petrides Elias

    Guys listen up , to unlock your iphone with SAM u have to…
    1) Have the sim card that your iphone had a contract on it.. example i have a locked at&t iphone and i want it unlocked to my vodafone sim. i have to put the at&t sim card in my iphone then download SAM, after u download SAM u follow the steps for the unlocking of your iphone.

    Yes you can unlock your iphone 4/4s
    Yes you can unlock baseband 4.11.08 and 4.12.01
    Yes it works for firware 5 / 5.0.1 / 5.1
    Yes you can turn on/off your iphone without losing your signal

    ITS VERY IMPORTANT FOR YOU TO HAVE THE SIM CARD OF THE COMPANY THAT YOUR IPHONE IS LOCKED TO. example AT&T. IF YOU DONT HAVE THE SIM CARD YOU CANNOT UNLOCK YOUR IPHONE.

    If you dont have the at&t or what other sim card that your iphone is locked to you can buy one from e-bay if you want.

    I have an iphone 4 running 5.1 on 4.12.01 and last night i jailbroke it and unlocked it with sam but i was having battery issues since it kept draining while on stanby so just a bit ago a decided to completly restore my phone to see if it would help and after i was done and it turned back up it was still unlocked. how is this possible? The iphone was locked to att and now it’s unlocked with telcel here in mexico and its not even jailbroken anymore.
