The SIM card in my Thunderbolt went bad back at the end of May. I was on a business trip and could not get a data connection. I took it to the nearest store and they replaced the SIM card which brought back data connection. Since then, the MyVerizon online account (Verizon's billing system) does not recognize what type of phone I have. It is a greyed out flip phone that says "General". Since this has appeared this way on MyVerizon, I am unable to get ANY OTA UPDATES that I was supposed to get on my Thunderbolt. When I try to download an update, it says it is checking for updated software now and then it just disappears. No Update! I called tech support over a week ago, they filed a trouble ticket with I.T. and said I would have to wait 24-48 hours...I followed up with them on Monday and they said they haven't had time to fix the problems with MyVerizon and to wait 24-48 hours! I called again today and no one in I.T. has yet to take the time to fix the problem. The technician tried to deactivate and reactivate my phone and screwed up my data plan! I had unlimited data and now it says I only have 2GB!!! Come on VERIZON I want all three problems fixed NOW!!! I pay over $130 per month !!!
