Are you on a Guido membership - the only membership that supports EU roaming calls/texts/data?
If so are calls and texts working ok?
If so then check your internet/APN settings and if the APN field has changed from 48months.liffeytelecom.com then edit it, change it back to that, save the change, reboot your interne phone and see if data starts working.
If it doesn't then you may need to contact 48 support.
See the link in my signature below.
Hope this helps.
