Can Not Connect to 4G

[Adam Z]

The last two days, my TB won't connect to 4G from 3G when I go into a very strong 4G area without me rebooting the phone. It's very frustrating. Any suggestions?

Set mobile data always on

Other than that, if it gets stuck, put it in airplane mode, and after a few seconds, turn airplane mode off. Use the widget might be easiest. You might have to do it a few times, usually by 2-4 times, it turns on for me.
