    Hey folks,

    Just a quick bit of advice to those who have purchased an iphone (for example on eBay) and later found that its locked to an unknown network and therefore unable to activate it and getting the "sim not supported message". I have spotted lots of online posts regarding how to find out which network its locked to without having official carrier sims to try out in the phone. people have said about model number but this will only give you a region as opposed to the lock status. simply take it into your local apple store and they can look up which network it is locked to. simple as that. Apple belfast were brilliant.

    You can normally look it up too.

    Settings > General > About > Carrier

    yeah, but this is only if you can get past the "connect to iTunes" activation screen. If like me you got an iPhone4 and was told it was unlocked / locked to your home network and it turns out to be otherwise then you cant get past the activation screen without an official SIM, instead I kept getting "The SIM card inserted in this iPhone does not appear to be supported" when I tried to activate so couldnt even get into settings to look. I knew it was a UK model but this means it could be either O2 / Orange / VOdafone / three and I certainly wasnt buying a microsim for each network to check. Just saying if youre faced with this issue then go to Apple and they can look it up on their systems and tell you what network its locked to. Im going into Vodafone tomorrow with my receipt to ask them to give me my NUC as per vodafone customer services.

    Iv just bought an iphone4 from a guy that said it was unlocked but then when i got there he told me it wasnt but i bought it anyway,when i go to,help and support and enter the serial number it says that the phone has not yet being activated,does this mean that what ever sim card i enter and activate it with,it gets locked to this network?i hope so,i dont have an apple store close by to take it to,thank you..

    Just look on the top left icon bar with the dots are and it will give you the name of the carrier.

    This only tells you the carrier of the current SIM card inserted in the iPhone.

    Again this only tells you the current carrier.

    just call apple, give them your serial number or IMEI and they can tell you exactly who it's locked to.

    At the iPhone hacks section.
    There's also 3rd party sellers that will look up what carrier the device is locked to for 99 cents on eBay or other websites.
