My big bundle SIM card expires today but it hasn’t been working while I’ve been abroad, I’ve been told to call 4444 to top up but I can’t make calls therefore I can’t top up. My O2 app isn’t working and I can’t order a new sim while I’m abroad. Any help?

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 (X)( https://o2uk.co/O2CTW) or Instagram ( https://o2uk.co/O2CIG) , they should be able to help.
