I bought a thunderbolt thinking it was a good idea now I not to sure. I bought 2 of them, one for my wife the other for myself. My wife's does not work right (phone will not make any sound )sending that one back. Mine will not activate, I am told it has something to do with the switch over from billing. A full week has gone by still no service. I have been told that there are several techs. Working on this problem. Anybody have a similar problem and was it fixed?
