Hey when I first bought my Thunderbolt I was in 4G connection at all times nearly, but today for some odd reason it has only been in 3G connection. I have tried hard resetting/ pulling the battery and also I have checked the settings to make sure they were correct. I have even put it in lte mode only and all I got was 1x bars. I guess I'm really curious as to why this has happened today.
Any answers are greatly appreciated,
I would also be curious as to why you could not pick up the 4G signal on the 14th when you posted.I competely understand your frustration. I want you to know that I have checked my references and I do not show any reported outages for the Fort Wayne, IN area on that day. I am, however, glad that you were able to connect to a 3G signal, so you could still use data on the Thunderbolt.
Since posting, has the issue been resolved? Are you now able to pick up a 4G signal?
Please post back and let us know, thanks!
