I have an oppo A9 2020 & cannot send SMS text messages.
Switched from giffgaff - no issues
I have done network settings, rebooted & all suggestions I can find on here... There seems to be a problem between Sky Sims & oppo phones from what I can see in these discussions... has anyone figured out the issue yet please?
I fixed the data issue by putting the data settings in manually & rebooting but still no joy with sending SMS ?
