    Was your iPhone hacked/jailbroken to be unlocked?
    If so, installing an iOS update on an iPhone that was hacked to be unlocked or restoring such an iPhone with iTunes re-locks the iPhone to the carrier the iPhone was sold as carrier locked with.
    What is the exact error message - the SIM card is not supported?

  • Iphone 4s not recognising new sim card keeps saying sim not valid?

    iphone 4s not recognising new sim card keeps saying sim not valid. Can anyone advise me please?

    There are three possibilities:
    1.  Your phone is locked to a different carrier and will not work with any SIM card except those from that carrier.
    2.  Your new card is from a carrier not supported by the iPhone.
    3.  Your new SIM card is defective.
    In order to determine which is the right answer you could try a different sim from the same carrier or try your new card on a different iPhone.   Also check to make sure your new carrier is a supported carrier.

  • Just got a used iphone 3gs and it won't see my sim card what can I do?

    Just got a used iphone 3gs and it won't see my sim card what can I do

    Seems your story has changed... not seeing is not the same as not supported.
    If the phone is carrier locked, you need a SIM from the carrier it's locked to to activate it.  The sim does not have to be active, it just has to be one from that carrier.

  • My iphone 3G wont allow my sim card to work

    After my son tried to install a softwhere upgrade on my iPhone 3G the phone will not accept my sim card. I have reset to factory settings but it still does'nt work.
    Any suggestions?

    Was the phone hacked to unlock it prior to the software update...I.E.-not officially unlocked? Sounds like it was. Updating software or restoring a hacked iPhone will re-lock it to the carrier it was originally locked to. Seems that's what has happened to you. You have two choices: 1. Get the phone officially unlocked, or 2. Re-hack it.

  • Iphone 4 SIM Card-what can be done with it?

    Last night I began taking up my 13 year old son's Iphone 4 before bed so that he will not be up on the phone all night.  I discovered he removed the SIM card when he handed it over.  I asked him why he did this and he did not give an answer.  My first conclusion was that he wanted to place the SIM card into his Iphone 3G, but I've read that it does not fit.  My other guess is that he may receive text messages or app alerts all through the night and wanted to keep it from me.  Does anyone else have any ideas as to he could gain or be hiding by doing this?

    The only reasons I can think of that the child removed the SIM are 1) he didn't realize that the SIM in an iPhone 4 doesn't by default fit in an iPhone; 2) he has an adapter so that he can use the micro-SIM in an iPhone 3; such adapters are readily available, or 3) he doesn't want you to be able to use the iPhone and perhaps get his text messages.
    I'd demand the SIM from him as well as both iPhones if it were me, though of course that's your call.
    Regards.

  • My phone says no sim card, what can I do?

    I was texting with someone, then my phone did some weird thing, and I shut it down to correct it.  When I turned it back on it said there was no sim card.  I havent touched anything.  How do I fix this?

    Try removing the SIM and putting back.

  • HT4972 Hi guys! i just updated my iphone 3gs OS, but unfortunately it's has refused to recognise my sim card. how can i correct this?

    I need help with my iphone 3gs?

    No. It won't. You can NOT activate an iPhone without a SIM. There are no exceptions. If the OP is getting a message that the SIM is not valid, not present, or not recognized, it will NOT activate.

  • HT2309 my iphone did not come with a sim card, what is redommended for the 4S?

    Obtain a micro-sim from your cellular provider.

  • Updated my iphone 3gs to the 5 ios and now my phone wont read my sim card when i reacticate it

    updated my iphone 3gs to the 5 ios and now my phone wont read my sim card when i reactivate it.
    Every time i connect it to itunes all it says is "There is no SIM card installed in the iphone you are attempting to activate." Even thought there is a sim card connected in my phone.

    Is the SIM from a supported carrier?
    Is the device carrier locked, officially unlocked, or hacked to be unlocked?
    Has the SIM been reseated?  If not, try that.
    Also, basic troubleshooting is reset, restart, restore.  Has any of that been tried?

  • I recently updated the itunes software and now my iphone wont detect the sim card! what do i do?

    I recently got my iphone unlocked because i wanted to change my carrier. today when i connected my iphone to the itunes it started updating the software! all my previous data was erased and now it wont detect the sim card! what do i do?

    Updating iTunes has nothing to do with an iDevice going into recovery mode.
    If the device is in recovery mode, restore it via iTunes on a computer.

  • HT1386 what to do if my iPhone wont read a sim card

    I have just purchased a iPhone off ebay and it wont read my sim card, any ideas on how to fix this

    Your iPhone was not unlocked, so you cannot pop in a sim and expect it to work.
    For all I know, maybe the iPhone was stolen.
    Anyway the only option you have is to get the carrier the iPhone is locked to, to officially unlock the iPhone.
    Also ask your seller the questions in this document

    If you do not get an answer, ask for a refund because the iPhone will be useless to you.

  • How do i set up my pre owned iphone 4 with my giffgaff sim card that was used in my iphone 3gs

    how do i set up my pre owned iphone 4 with my giffgaff sim card that i have been using in my iphone 3gs
    My 3Gs is on its last legs.... I've just bought a second hand iphone 4 which is unlocked......I put my giffgaff sim card in the new phone and it says activation required ......then it asks me for a passcode???  PLEASE HELP!!!! I have no idea what to do xx

    You need to connect the phone to iTunes and then try activating it from there and restoring it as new.
    If you have further problems and especially as the iPhone you have bought is second hand, it could be that it is not unlocked.  Are you sure that it is?  If not, then you'll need to speak to the person that you purchased it from.

  • My iphon 5 said "only compatible sim cards from a supported carrier may be used to activate iphone. please insert the sim card that came with ur phone or visit a supported carrier's store to receive a replacement sim card" what do i do???

    my iphon 5 said "only compatible sim cards from a supported carrier may be used to activate iphone. please insert the sim card that came with ur phone or visit a supported carrier's store to receive a replacement sim card" what do i do??? i leave in diferent country now!!!???(((

    in many countries to make phones seem less expensive
    carriers pay most of the phones price for the customer
    but this come at the cost of the phone only being able to work
    with the carrier this is called a sim lock
    the only people who can remove a sim lock is the carrier which
    the phone is sim locked to they been doing it like that for at least 20 years
