I got my girlfriend a used MyTouch SLIDE that was unlocked. She is using it with TelCel in Mexico I have G2 and use MySimpleMobile First few days were fine, no issues, sending texts back and forth no problem then after a few days I get a message that looks like something typed in the low end fo the ASCII alphabet and sympbols %@#$%#@$% /' etc very strange, than blank. Every message either comes blank or with very strange characters. She receives just fine. She can read mine and she gets other messages, can type and send messages to her sister just fine in Mexico. So not the keyboard and she can call me on the phone from Mexico no problem as well. Sending SMS messages back and forth from Mexico via TelCel is usually pretty easy. She had a BlackBerry Tour for a while and it worked great. So I'm not sure what the issue is. Could it be software? Maybe switch it to be 2G only??? I'm baffeled?
