Mobile phone unable to make or receive calls I have two mobile phones on my account with id mobile, my phone has a 4G Sim, my wife’s has a 5G Sim. We have never had any previous issue with our mobile phone service. Yesterday 11/09/24 my wife informed me that she was unable to make or receive calls from her mobile. My phone is working fine it has a 4G Sim, my wife has a 5G Sim. She still has internet access, emails are working , text messages , Whatspp etc are all fine and working as normal. I tried all of the suggested solutions, reset the phone , checked and removed the Sim, nothing has changed. We have not altered any of the phone settings. Is there a problem with the 5G Sim ? any advice would be gratefully received. Failing this a trip to Currys may be required.
