Background: I've had my thunderbolt since release with minor problems. When the 4G network went down I edited my modem settings to jump back on the cdma 3g network. Since the 4G network came back up I've switched my settings back to default. Problem: I'm starting to notice now my texts are not being sent and I'm not able to receive text messages. I have no sms errors and no messages to alert me on my end of any problem. My messages to me look like they have been sent but none of my contacts have been getting any of my messages and I'm not bale to get theirs. I have no idea what is causing this. Any input would be great. Thank you.
