My basic plan does not allow to change APN settings (greyed) so I do not have data access (except with WiFi), I guess I need a "new" SIM if I change my plan for a data plan because the current SIM prevents me accessing mobile data outside a WiFi hots...
I do not have access to mobile data. I cannot edit default APNs settings (greyed) nor ADD a new APN (tapping the 3 dots at upper right corner of display). How to solve this problem? (new unlocked moto 2020, android 9)
