Ok so I just got my HTC Thunderbolt yesterday and it wont connect to the internet over the Verizon network. It works just fine when it is connected to wifi. I have tried turning the mobile network on and off and everything but it still wont.
BTW I can still call and text but everything that requires the internet does not work.
The guys at the verizon store did not register the sim card correctly. I was able to use the phone and text but not the web. A very nice lady at tech support fixed me right up. Works great now.
I had the same problem and tech support was going to send me a new one but I went into the store and they fixed it right up. They said it was messed up during the initial activation. No problem with internet over the last couple of days. Now for my other issues......
I live on the Fringe of 4G network. My Brother in law had this problem, and hit battery life was subpar.
This fixed it for him
Factory Reset his phone
He used the dialer and put in *#*#INFO#*#*
Changed the CDMA+LTE to CDMA Only (PRL)
Then his did his setup as usual, and so far he hasn't had any problems since. If you want to try that and see what happens by all means try it, but don't get mad at me if it doesn't work
You can go to app store and download the app called Phone Info then you can switch the settings anytime without having to put in the code all the time ,the app takes you directly to the settings.
I had the same issue and the Verizon Store confirmed the problem and said a factory reset was the only way to get the 3G and Data service back. I did the reset while in the store and it fixed the problem.
