+1 !I struggled for four days, trying to get my Motorola G7 Power (official Android 10) to get a cellular connection. Then I stumbled on another XDA thread, & it had a clue!
My solution? Under:
Of course you must have Mobile data on.
- Network & Internet
- Scroll down to WiFi preferences.
- Turn on Avoid bad WiFi connections
This causes the phone to treat the lack of an Internet connect as "bad", & that turns on mobile data: The "4G/LTE" icon lights up, & I was "on the air".
I hope this works for others.
This is the obvious and basic setting to be done, even before trying to connect AAW !
