The problem am having is at work i got alot places that all carrier phones loose signal but when i reach a different spot with good signal sometimes i got to restart the phone so it get back to 4 g lte this never happend with my note 9 and i used for over a year in the same circuntances it this similar to what is happening to you??
I reset my network setting and then extract my sim card and put it agian i dont not wich one of both resolve the problem but i didnt have more problems after that so try it maybe works for you too
I am using a note 10+5G in the UAE with provider etisalat. I have tried all the solutions.
Phone changed ( another new note 10 + 5G)
Network settings reset
Provider trouble shoot and reset
Absolutely no use. Nothing helps. When I reach my work place, I do not get any data. Calls do work.
I need to switch to flight mode, then back. Data works. All of a sudden, data would stop. No idea when that would happen. Need to keep checking. Hope samsung fixes this issue. I use a note 10 + 4G , works absolutely fine.
