Calls dropping at 15mins
Since updating iPhone 11 Pro Mac to 16.2 my calls drop out after 15 mins. Most businesses put me on hold for longer than 15 mins so it’s impossible getting onto anyone.
The call still looks like it’s connected on my phone eventhough it has disconnected. I’ve tried removing sim and cleaning it. Turning aeroplane mode on and off. Tried resetting network settings. Turned phone off a number of times.
i did actually get 1 call to last 40 minutes but then my other calls don’t.
Im running out of ideas. Thank you
iPhone 11 Pro Max, iOS 16
