    The first day I had my Sprint 4S it gave me a sim failure error code and I had no connection to my Sprint service. As a quick fix I did a reset and it went away. 2 days later (today) I received the same error.

    Did anyone else receive this error? If so, what are the possible fixes?

    Try removing the sim card.

    I was under the impression that since Sprint uses CDMA tech there was no sim card. Am I wrong?

    There's a GSM sim in it, for international roaming since it's a world phone.

    Hi

    Received my 4S yesterday and have been encountering the same problem. Some testing indicates that the SIM failure only occurs when I have the phone in my case, which is the same one I've been using for my iPhone 4.

    The case fits the phone just fine, incl the buttons on the side, but it must have an adverse impact on the 4S, perhaps due to antenna design.


    Fitting the case produces the SIM failure error within a couple of minutes to about an hour, especially when the phone seems to be handing over between carrier radio frequencies. I've been using the phone without the case for a number of hours now and have not received the error again.

    If anybody else is able to reproduce the problem, please do confirm.

    Regards

    I had the same SIM failure starting about the 3rd day of usage. It was not in any type of case so that was not the cause. Also, after receiving the msg. my phone would then show "no service" and the only way to clear was to turn completely off. Sprint did not know what the problem was so I took the phone to Apple where they rebooted my phone, the problem continued. They replaced my 4gs and the problem continues with the replacement phone.

    Just out of curiosity, is it a Black 4S or a white 4S? I have the white 4S, have had it in three different cases (latest is the Otterbox Defender), and have had zero signal or SIM problems with it.

    Had this problem when I had my sprint 4s replaced becausetescreen looked washed out then a normal screen. Restore the phone through iTunes that should fix it. If not go to dialpad(sprint ) and type ##873283# but first restore it .

    The problem has never reoccurred for me ever since I installed my Elements Case Vapor Pro. Not sure if it had anything to do with the Sim issue but just thought I'd mention.

    Ok first off all 4s have a sim (gsm) portion and CDMA portion
    AT&T , Verizon , Sprint
    Look on the side of your phone
    AT&T uses this as there service (gsm)

    Verizon and sprint use a esn (CDMA)

    Even thou Verizon and sprint do use it
    Remember iPhone 4s is a world phone

    Meaning Verizon and sprint put som cards in so if you leave the country you can roam and use gsm carriers in other country's so your phone works

    As far as the issue with the error I would first take sim out and put back in

    Second if it happens again I use with no case see what happens

    Try to duplicate the prob To see if it really is your case

    Still try a restore

    If still happens take out sim and leave it out (except AT&T ) see if it happens

    If it still happens I would take it to apple and replace

    I had something similar happen except I couldn't get to the home screen at all. It was a nightmare trying to get this resolved. Sprint said it was an Apple issue. Apple said it was a Sprint issue. Even though Apple gave me a new phone (did not resolve issue) since it didn't work they said I had to go back to Sprint.

    I went back and forth four times until Sprint finally owned up to it. The bottom line is that they are responsible for the SIM card.

    I was without a phone from last Sunday until yesterday when Sprint exchanged the phone for a new one which included a new SIM. Evidently they don't have any extra SIMs anywhere in the company.

    FYI White 32GB iPhone 4S.

    EDIT: I and Apple tried everything from restoring, resetting network settings and everything in between. Nothing worked.

    When I did a warranty replacement on my Verizon white 32gb, I couldn't get it activated due to a bad SIM. I took it out and got it to activate that way, but when I go to Verizon's site, they still show my phone as not being activated. Going out of the country next month, so I need to get it straightened out soon.
