Data coverage in Europe - not working

[ICH]

Hi, I'm due to go to France in the new year and I wanted to get my data coverage fixed. The monthly contract I am on should allow me to use my data in Europe, however, I have been on a few trips over the past couple of years and my data has never worked abroad! My phone will recognise I am in a different country and when I have my data on nothing happens and I am unable to use it. Could this be resolved please and it is within my contract that this is something that I should be cover for. Thanks

Some things to try:
Check data roaming is on in phone settings.
Manually search for another network
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 ( https://o2uk.co/O2CTW) or Instagram ( https://o2uk.co/O2CIG) , they should be able to help.
