  1. Just got new iPhone 11 and calls fail. i tried every single option below, including rebooting. I did notice that I don’t have a toggle for caller ID – it just never loads and keeps spinning. Help!

    • I have the exact same issue on my iPhone 6S Plus. The call works fine, but whenever someone hangs up, or I do not pick up the phone, I get the message saying “Call failed”, and an option to call back or exit.

  2. This problem can also be solved turning the cellular mode to “data only” cause some of the carrier may cut the phone automatically if 4G is on during a phone call. hope its help cuz i had been struggling from this problem for some days. :)
