So I just set up my phone a couple of days ago and upgraded from the Optimus. I really like it so far, but I cannot send or receive text messages. I've looked at the issues everyone has been having and still nothing. I did a soft reset, hard reset. restored to factory settings (not once, but twice), cleared cache, etc. My signal strength is between 2-3 bars. I'm at a loss, and can't find anything else. Anyone got any ideas? I also tried airplane mode and that didn't work..
