Welcome to the community and thanks for posting. So sorry to hear you've got no mobile data.
I can see you've already called in and the notes say the issue was fixed. Could you please answer the following questions:-
Are you still having issues?
Are you saying Wi-Fi is fine but 3G is not?
Look forward to your response.
That's excellent. news LynnieD.
I'm really pleased to hear it was a quick and simple fix.
Let me know if you need anything else.
