Mobile data setting

[bwallx]

Android 9 Blackview A80 Pro
Although all my settings are on for mobile data and associated settings too, my apps refuse to work unless there is wifi.

I increased my data limit even though it was only a few Mbs not Gbs as expected. I can't see any further options. I messaged my provider but no answer.

OK well who's your carrier, what type of plan is it that you have and what's your location?
The more information you can give the better

So the Advanced Network Manager is showing "NO" or "NONE" for SIM, phone, and network. plus "N/A" for everything else in Cell Information !?

Check the SIM is inserted properly? Do you actually have any carrier service at all? Is your account paid up to date, or have sufficient credit for calls and data? Think you definitely need to contact your carrier about this matter.
