i had just bought and activated my ''my touch Q'' phone from t.mobile on Sunday everything was going and working out good but just yesterday i would send a text to my girlfriend and she said that she would only receive half of my of my text or she would receive nothing and the same thing happened today again at 2:19 pm so i just shut off my phone. could it be that i have the wifi from my house connected to my phone and its messing with my 4g
or could be that i have that i have downloaded apps to my phone or go on the internet alot?
or because i use it 24/7?
can somebody please help me ?

please!! & thank you
