My phone won't send or receive texts, sometimes it even says my number is unknown! it won't let me open any apps for long either, and this'll all randomly happen and it won't go away!! help!!
iPhone 4S
Quit the App by opening multi-tasking bar, holding down the icon for the App for about 3-5 seconds, and then tap the red circle with the white minus sign.
Relaunch the App and try again.
Restart the device. http://support.apple.com/kb/ht1430
Reset the device. (Same article as above.)
Restore from backup. http://support.apple.com/kb/ht1766 (If you don't have a backup, make one now, then skip to the next step.)
Restore as new device. http://support.apple.com/kb/HT4137
For this step, do not re-download ANYTHING, and do not sign into your Apple ID.
Test the issue after each step. If the last one does not resolve the issue, it is likely a hardware problem.
