I've been experiencing problems with my phone for about 2 days now. I can't use it to make calls or texts and I don't get any from anyone either. If I literally drive 2 miles down the road, the phone works. I've tried to reset it using *228 and update the roaming settings. I've taken the battery out while the phone is on, and even manually powered it down, but nothing works. The phone shows I have full signal strength until I actually make a call, then the bars disappear and the call never connects. The same thing happens when I try to send a text; it just never sends. I can connect to the internet, so there's no problems there. I appreciate any help.
