Can’t use mobile data when no WiFi.

[Donnalou36]

Hello.
Just wondering if anyone else has had the same problem.
My phone can’t use mobile data at all when not connected to WiFi. 4G or 3G is not working. I can’t send texts or use the internet. I contacted o2 as I established it was a sim problem (I tested the card in other devices) so they sent me a new sim.
New sim arrives and is set up, but still having same issues.
Does anyone know what I can do? There is no issues on the account o2 checked.

Thanks in advance.

On iData apn.
That's why you need to change to mobile if it fails abroad.

Must be another problem then.
