User level: Level 1 (12 points)I am having an issue with my iPhone 17 Pro Max in Kosovo after updating to iOS 27.
I am completely unable to make or receive cellular calls, even though my 5G mobile data and SMS text messaging are working perfectly.
My carrier, Vala, confirmed that everything is fine on their end and stated that this is a bug with the iOS 27 update. I have already tried standard troubleshooting steps, but nothing has resolved the issue. The iOS 27.0.1 update did not fix it either.

And what standard troubleshooting tips have you done?
you'll need to escalate the issue with Vala, since you pay them to use their service.
