Friends -
I have had and HTC Thunderbolt since they were released. Last year, my Thunderbolt began requiring me to activate the phone. Soon, it was completely not working. I took it into the store and the tech told me the phone was no longer being recognized by the network. We changed the SIM card and I left. A few days later the same thing happened. The telephone was replaced. It has happened several times since then. So, I am on SIM card 3 and phone 3 or 4. All Thunderbolt. Is this a known problem with the telephone? I have a hard time believing it keeps happening and it is not something with the telephone.
