AT&T LG Thrive p506 Won't Receive Text messages

[DMNelson]

My LG Thrive will not receive text messages. There is no problem with sending messages, I just do not receive messages. Nothing else appears to be wrong with the phone. I have tried the basic things such as powering on/off, removing the battery, airplane mode on/off, but none if this made a difference. Any ideas of what I myself could try?
