Thank you so much. I'm not technically minded and it took a bit of searching through the settings. I followed your instructions step by step and I'm now sorted
Glad it helped.
Some of the instructions elsewhere are not 100% correct but these ones have never failed:
Do you have a Guido membership?
If not then nothing will work - no calls/texts/data.
EU roaming only works on Guido.
If you do have a Guido membership then do you have a local network connection or not?
Are calls and texts working?
If not then manually scan for networks and try to connect to one of them.
If calls and texts are working but data is not then check the APN field of your internet settings.
If it has changed from 48months.liffeytelecom.com then edit it, change it back to that, reboot and see if data starts working.
If none of that works then you'll have to contact 48 support for advice.
See the link in my signature below.
Hope this helps.
