I went to Spain for a few days over Christmas, and after I left the UK border, my O2 card stopped working. I could use it on my previous trips to Europe, so I'd like to know what the problem is?

This is a customer to customer community, not O2, so we cannot access your account, sorry.
You need to contact O2.
Message them on Social Media. Facebook (https://o2uk.co/O2CFB) , Twitter (X) (https://o2uk.co/O2CTW) or Instagram (https://o2uk.co/O2CIG) or give them a call on 202 or 0344 809 0202 (contract) 4445 or 0344 8090222 (PAYG).
If it happens again, some things to try:
Check data roaming is on in phone settings.
Manually search for another network
Turn off 5g
Enable 4g calling (if on contract)
Change your data APN to "mobile.o2.co.uk"
Check with O2 whether you have a roaming bar on your account.
Please select the post that helped you best and mark as the solution. This helps other members in resolving their issues faster. Thank you.
