Whilst in Northern Ireland and southern Ireland I could not make or receive any calls. I could see incoming calls but when I answered the line was dead with no sound at all and the receiver could not hear me.
Roaming was switched on both on the app and handset. I could however receive and send text messages with no issues. Since coming home I have searched the Hubs for answers, checked the APN which was set up correctly so I'm a bit stuck.
I'm going to Italy in a few weeks and would like to try and resolve this before I go away again.
Many thanks in advance
