I recently moved to ID Mobile and cannot receive calls or make them. I have updated my phone and set my saved number to +44 rather than 0. I switched the phone on and off and set the phone to 5G and 5G Auto. None of the other advice online for this issue has worked.
It is an iPhone and I am now very desperate for advice and would preferably like to speak to someone from ID Mobile as all the advice they have given on this page has not worked.
