Im not sure if its sprint or my phone but almost 70 percent of the time I cannot send text messages, connect 3g, and when I make phone calls I get nothing but busy signals. When I send a text I just get a triangle and a explamation mark thing.When people call me it just sends them straight to my voicemail.I am out of town but where I had 3g connection yesterday at times all day today I had nothing. Does anyone have a clue whats the deal?
