Well EU roaming only works on Guido. The only thing that I can suggest is that you contact 48 support and ask them if they can terminate your Don membership early (you'll lose any remaining membership allowances) so that you can buy a Guido membership and have that start immediately so that roaming works.
Hi thanks a mill dalyer, it cleared things up yes. Have membership till late Nov tho so bit of a pain to be honest that the other memberships aren't on roaming too. Thanks for the reply tho! 🙂
