Hi, I've had my motorola milestone xt720 for a few months, and recently I had to wipe it because of a virus. Now I cannot receive calls or make calls, and my signal is extremely poor at best. I can still send texts (when I have signal of course) but even when I have signal I still cannot make calls or receive them. Everything else on my phone works perfectly fine, but it isn't much use when I can't communicate with anybody. It also can't be my network (vodafone) as I tried my sim card in my old phone and it worked perfectly fine. Not sure if maybe there's something I haven't set up properly? I didn't set up the phone when I first got it, it was a present. Ideas? I'd appreciate any help Thanks.
