Classic PAYG flash balance notification not showing

[Mcc2]

I have just swapped my sim from an android into a new IPhone and now I don’t get the balance notification after making a call. I have the O2 app installed but when I go to Settings then notifications the app doesn’t appear on the list. Is there some way to get the balance notifications appearing again after every call or text?

The notifications come from the network, not the app, so call O2 on 4445 to enable them.

Why did it work on old phone on same sim and not doing now on new phone.?

There are different account settings required when using an iPhone.
