Iphone 16 won’t receive calls
My iPhone 16 won’t receive calls and hasn’t done for at least a month. I have tried everything recommended on the live chat - reset the network settings, checked for focus / do not disturb / call forwarding settings. Nothing works. I am missing important calls from the doctor, my children's nursery etc. I have a an esim so can’t change the sim. Please advise what to do as it is unacceptable to be paying for a phone that can’t receive calls and I’m particularly frustrated there’s no phone number you can call to resolve this.
