Are you using a PAYG or a Contract SIM in your phone, @GAT1?

Roaming in most European countries with O2 is free, up to 25GB per month for up to 63 days, no specific bolt on required - but as countries remove their older 3G infrastructure, you may find that you need to use some 4G features, or 5G, which are unavailable to O2 PAYG customers.

I fo here: Guide: Roaming MegaGuide @GAT1 - and if you have an iPhone, you may find your APN is incorrect for roaming.

@GAT1 

If you were using a dongle, they don't work abroad.

If you are referring to your phone, 

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.
