Can't receive text messages; everything else about phone works fine Starting at exactly 3pm (EST) on Sunday two weeks in a row my phone could not receive SMS text messages.  It could send SMS, send and receive calls, and send and receive MMS (mutli-media messages).  I was using the stock messaging client.  This is on an Samsung Rugby Smart running Android 2.3.6, with AT&amp;T as the carrier.  How do I get text messaging to work again?
Quick Answer:

Put the SIM card in another phone for a few minutes to reset the network registration and then move it back.



Things that I tried that did not fix this problem:


Restarting the phone
Removing and reinserting the sim card
Uninstalling the Skype app
Calling AT&amp;T support (611) and asking for them to reset the network registration of my phone
Restarting my phone in safe mode
Booting my phone into system recovery mode and wiping the cache partition




Full Answer:

AT&amp;T indicated that it was a problem with the network registration, given every piece of my phone's communication worked except for receiving SMS.  This turned out to be true.  The solution was to put the sim card in another phone, which overrode the network registration for my number.  After about a minute, the second phone received all of the texts that the first had not been able to get, and then I could move the sim card back into my regular phone and receive texts as normal.
