Replacement sim not working whilst roaming

[CieranA6]

I recently got a replacement sim and it's not working abroad whilst I'm currently in Portugal. Is there anything I can do to fix this?

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.
