My e815 has been acting funny all evening not getting good reception and dropping calls in places where I have always gotten good signal. so i knew it was probably time to update my towers. I did this and now my phone say no service and is not picking up any type of signal no matter what i try! I dont know what to do. I cannot call alltel or even my voicemail from it. this is my only line of communication besides the internet obviously... please I will take any suggestions! panic is setting in! thanks in advance.
