I have done that multiple times too, as soon as I connect to wifi at home and drive to work, I don't have data once again unless I turn on and off flight mode as I said earlier. Resetting and rebooting and everything else doesn't fix the issue at all...
I javw been having no data all this week.. I have to turn on and 9f flight mode each time... what is going on with this. Chat bot is no help ans can't get help elsewhere..
