iPhone does not ring always
I have asked this question, I was in touch with iPhone provider here yesterday. We did all the things that were suggested here and online with provider. An important call was sent to me 11:15 AM ( iPhone 16 updated) while I was online with the network modem within 36" I did not get the ring, but I did get one from that provider 2 hrs later.
WHAT HAPPENED? (frustrating)
iPhone 16 Pro, iOS 18
