Mobile data not working, google pixel 5

[JBS]

Hi,

I got my Pixel 5 about a month ago. The mobile data won't work. If I take the sim out, swap it and then put the right one back in, it works for about an hour but then nothing.

Sim has been activated and it's got signal so I just don't know what the issue could be.

Any advice?

Thanks,

Jennie

I'd call O2 for a new sim first off to see if that helps.

All numbers are in this guide Guide: Coronavirus Community Help and Support 
Or 202 from your O2 mobile.
Advice from an O2 Guru to get through:
When you call 202, you will be asked for the reason you are calling.
Stay silent for 15 seconds and you will be taken to the keypad options.
Press 2 for Everything Else
Press 5 for More Options
Press 7 for Anything Else which will put you though to someone.
You can also try saying "Upgrade" or "Fraud" to be connected to an advisor.
