I upgraded to this phone just before Christmas. It worked great until about two weeks ago - about a week after I got it. I can't send texts! I've tried while out in a 4LTE signal, 3G signal and we have a network extender at home and it won't work on any of them. Just immediately failed. I had a Droid X before and my daughter and husband have the X still and have NO issues. I don't get it. What the heck is going on? How do I fix this?? This is a major issue and if I can't find a resolution soon I'll be forced to go back to the Droid X. I need to have texting ability. Keep in mind: I receive texts just fine. I can receive/make calls with NO issues. It's only for me sending a text and it doesn't matter to who it is, or what signal I have (even full 4LTE results in fails constantly). Any help?
