Data roaming in Greece

[Gr157]

I am in Greece and my phone has no data. I have a pay mouthy plan with allowance in all of Europe 

I have calls and messages coverage but no 3G/4G

Have you got an iPhone?

If so, then go into data settings and change your APN to "mobile.o2.co.uk"

See if that helps.
