Wifi calling is not working on my iPhone 12 after updating to iOS 16.4.1

Just have the same issues and solved by doing: Disable WiFi , and make sure your GSM Cell Data is Enabled, then go to Wifi Calling (under your eSim) or your SIM , then Choose Enable WiFi Calling. If it is enabled already, then disable it & re-Enable it again. WiFi calling must send the signal back to GSM operator to acknowledge that WiFi Calling is active. WiFi data only never make this to work.

Since Wifi Calling is a specific cellular carrier service/feature, I suggest that you contact your carrier and explain your problem.

Then it's likely an issue in Airtel's configuration for your device; give them a call and see if they can straighten it out.

I had the same problem. I reentered all my emergency contact info in the prompt manual ( it was auto entered when the prompt came up) and it fixed it. Now my Wi-Fi calling stays on.

I resolved this issue by selecting going to network selection and selecting any other provider which does not have any signal.

Now it take all the calls from wifi only
