I am in Spain and my phone is not working despite me switching over to Guido and my phone showing that I am connected to Orange. I urgently need this matter rectified please and would be grateful for your help. Thank you.
Check your internet settings. If the APN field has changed from 48months.liffeytelecom.com to something else then edit it, change it back to that, save the settings, reboot the phone and see if data starts working. If it doesn't then you'll have to contact 48 support. See the link in my signature below.
Hope this helps.
I am not a 48 employee so if you need to contact 48 support then use option 3 or the chat facility here.
