I am unable to make or receive calls. I've restarted my phone and removed the sim a number of times, but it's made no difference. I've also checked settings and there's no call barring etc on my phone. Is this to do with the switch to O2?
Thank you for your post and welcome to our forums 😊
I am sorry you are having issues with your phone and are unable to make or receive phone calls. Can you please give us some more info so we can best assist you?
Is this a new SIM if so when did you receive this? Or have you had the SIM for a while and just started having issues? Are you having a number ported over?
