We are on T-Mobile. Just upgraded to iOS 16.2 (automatic upgrade feature is on). Notices phone calls are getting dropped after 30 seconds, after 2 minutes, after xx seconds -- completely random.
Turned off wi-fi calling and everything seems fine. What is going on? I thought this was an old problem but still happening now.....
I believe this is a race condition in iOS 16.2. When the signal strength of 5G oscillates like a sine curve, the phone is trying to switch between 5G, LTE, and Wi-Fi. This is leadings to dropped calls, or even dropped conversations when in the call. Dropped conversation is defined as the person on the other end not hearing me speak or I hear every 3rd or 4th word the other person is speaking. This happens all the time with 16.2. This is a definite bug in iOS16.2.

Hi rasriniv,
Thank you for posting in Apple Support Communities!
Does this continue on any Wi-Fi network that your device is connected to?
The symptoms you've described could be due to interference.
As a troubleshooting steps, you can confirm there is no wireless interference like mentioned in this article: Resolve Wi-Fi and Bluetooth issues caused by wireless interference- Apple Support.
If this continues, you may want to reach out to your carrier to confirm there are no issues on their end since Wi-Fi calling is a carrier feature.
Have a good one!

I’m having the exact same problem but my carrier is Verizon. Dropped calls started after upgrading to 16.2. I’ve never had this problem until after upgrading. I don’t think it’s an issue with what carrier we have but it’s looking like the issue is with the upgrade itself.
iOS 16.2 and dropped calls on iPhone 12 Pro Max and iPhone 13 Pro.
