Q: After 8.3 update, 5c no longer connects to wireless carrier!

After completing the 8.3 update, my iPhone 5c will no longer connect to my wireless carrier.  I cannot receive or send calls.  The only way I can text is if I'm connected to my WiFi. I took my phone to the store and they replaced the SIM card, which didn't help.  I was advised to come home, backup to iCloud, reset the phone to factory settings, and see if that helped.  I did that, and now I keep getting an error during phone setup saying "the activation server is temporarily unavailable."  Now what do I do?  They told me not to connect to iTunes on my computer because it could have stored "bad data" from a previous backup.  Any suggestions would be very much appreciated.  Thanks!

iPhone 5c, iOS 8.3

    Hello RacerChick81,

     

    Thanks for using Apple Support Communities.

     

    The reason you were told to not plug in your iPhone into iTunes on your computer was to ensure you did not restore from a previous backup.  In this instance you will likely need to put your iPhone into recovery mode and the plug it in to your computer.  For further troubleshooting steps on this issue where you get an error that the activation server is unavailable, please follow the directions below.

     

    Try these steps:

    1. If your carrier provided a SIM card, make sure it's in your iPhone.
    2. Restart the iPhone.
    3. Try to reach the activation server another way, then try to activate.
      • Try connecting to a known-good Wi-Fi network if you can't activate using a cellular data connection.
      • Try connecting to iTunes if you can't activate using Wi-Fi.
    4. Restore the iPhone.
    5. Check the system status for iOS Device Activation. If the iOS Device Activation status isn't green, try activating your iPhone later.

    If you receive an alert message when you try to activate your iPhone, place the iPhone in recovery mode and perform a restore. If you still can't complete the setup assistant due to an activation error, contact Apple for assistance.

    If you're asked to enter a password to proceed with activating the iPhone, Activation Lock might be enabled as part of Find my iPhone.
