Unable to receive calls from certain people
I have gone through an iPhone 7, XS, and 11 with service through Verizon, then T Mobile, Signal, and back to Verizon. During all this time my phone works fine, except my mom and a few others have reported they cannot call me. They can text and FaceTime me but the call says I’m unavailable. I had big news coming from a 4 star admiral and he was unable to get through, so this is a problem and it’s not a blocked number or the service providers issue. Nor is it something that can be fixed by deleting contacts and adding them back as contacts I don’t have can’t call.
thoughts?
