Hello, I just purchased a LG G2X. I like everything about it except that I cant send text messages. I can receive text messages, send and receive photo messages, and send and receive phone calls, but still no sending texts. I have tried changing the apn settings with no luck. I also dont think its a sim card issue because my old phone would work no problems. Is this something that I need to fix on my end, or something thats wrong on T-Mobiles end? I dont know what else to do.
