I have the same problem, says T-mobile, a minute later it says Emergency Only and it has nothing to do with the signal, because it is the same. What a Piece of **** this phone is. Besides me not being able to use the phone to call or text anyone, the FM Radio is good for nothing. I can honestly say that I would not reccomend this phone to anyone, and The Chinese dont even care, they want you to pay shipping to return it both ways? What a crock, thats like paying for half the phone again, just because the seller is selling items that are not as described.
