Hi @Anonymous This could either be a sim card issue, phone failure or a problem with the network....Have a look at this trouble shooting guide
https://www.o2.co.uk/help/network-coverage-and-international/self-help-guide-for-network-problems
To check that it’s not your sim or phone:
- turn your phone off and on again to refresh your network connection
- toggle your flight mode on and off
- go to your phone settings and choose the O2 network manually
- try using your phone in a different area
- try your sim in a different O2 phone
- try a different O2 sim in your phone
Also check your network status here http://status.o2.co.uk/

Is this when using a specific app or just on the home screen?
Check if it stops if you close all running apps too.
