Make sure you're connected to a Greek network as all should work like at home.

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.

In order to make/receive calls, send/receive text messages, or use mobile data abroad - you need mobile network coverage. Does your phone show a connection to any Greek networks?
