    Default "No Sim Card" Problem?

    Well, for some reason after trying to unroot my phone (using this guide: ) I get a message saying "No Sim Card", I even tried to restore my phone to a backed up version that I did before trying to unroot my phone, still no luck and still same message saying "No Sim Card"

    Does anyone know how to fix this issue? Would be appreciated

    Edit - Upon updating it (settings -> System Update -> Update Samsung Software) it seemed to have fixed it within the 2nd or 3rd update, is there anyway I can transfer my apps, contacts, text messages, etc off of the backup version? For some reason my backup version has the "No Sim Card" error although its updated ;|

    I had the same problem. I went to the Verizon store. They replaced the SIM card at the no cost. That resolved the problem. I think I got lucky.

    Welcome to A|C, plagiarize.

    Just to make sure, you do have a Sprint SPH-L710 version of the Galaxy, right?

    If not, I'd suggest reposting in the forum for your carrier. But assuming you do have a Sprint, the SIM card in the S3 is non-removable. I've only seen this happen with phone that had the MEID altered, and were unrooted without changing the MEID back to the original value. Is that the case with your phone?

    In terms of the backup, the answer is maybe, and it depends. How did you create the backup?

    The Play Store will remember the apps you purchased and downloaded and, if you're using the same Google account, will let you download them again. That won't get your settings back, unfortunately. If your contacts were backed up to Google (you have that option when you first set up the phone), you should get them back the first time you log into the account.

    Oh, one more thought. Have you tried restoring your backup, with the error, and then doing the same thing you did on your new install to try to eliminate the error?

    My thought is some Superuser apps have a full unroot option. You can try that. I am under the impression that you are rooted again?

    Hey I figure out how to fix this problem, "no Sim Card" This occurred after a modem flash. I flashed LF9 modem over another previous modem. All you need to do is use the free gs3 roms modem flasher and go back to which ever modem was on your phone prior to the flash. it will go away then.

    It sounds like you flashed a modem file that wasn't valid for your specific model of phone and carrier.

    in the past i was able to flash any modem for the sprint gs3 but after a samsung update it seems to have blocked modem flashing and only allows modem "LI3" to be flashed without the "no sim card" error. The LF9 modem was had the best reception in my area, but now with the LI3 modem, i never have bars showing only maybe 1 or 2 even sometimes no bars show, but never really a reception problem and the performance of the LI3 modem is similar to the LF9 just without the visual confirmation of the signal bars present.
