Some things to try:
Check data roaming is on in phone settings.
Manually search for another network. Try T-Mobile
Turn off 5g
Change your data APN to "mobile.o2.co.uk"
Check with O2 whether you have a roaming bar on your account. Do this via social media
If you message O2 on Facebook ( https://o2uk.co/O2CFB) , Twitter (X)( https://o2uk.co/O2CTW) or Instagram ( https://o2uk.co/O2CIG) , they should be able to help.
