Wi-Fi calling won’t stay on— don’t get emergency page, iPhone 11

Good day 1000wayne, 

Please make sure your carrier supports Wi-Fi calling, as this can have an impact on using the feature. You’ll find a link in the following article on where to do that - Make a call with Wi-Fi Calling

If you can't turn on or use Wi-Fi Calling, make sure that your carrier offers Wi-Fi Calling and that your devices have the latest software. Then, follow these steps if you can't turn on Wi-Fi Calling or make a Wi-Fi call. Wait two minutes before you go from one step to the next.

1. Go to Settings > Phone > Wi-Fi Calling and make sure that Wi-Fi Calling is on.

2. Restart your iPhone.

3. Connect to a different Wi-Fi network. Not all Wi-Fi networks work with Wi-Fi Calling.

4. Turn Wi-Fi Calling off and then on again.

5. Go to Settings > General > Transfer or Reset iPhone > Reset, and tap Reset Network Settings.

When using the reset network settings reset, Return iPhone settings to their defaults

All network settings are removed. In addition, the device name assigned in Settings > General > About is reset to “iPhone,” and manually trusted certificates (such as for websites) are changed to untrusted.

Cellular data roaming may also be turned off. (See View or change cellular data settings on iPhone.)

When you reset network settings, previously used networks and VPN settings that weren’t installed by a configuration profile or mobile device management (MDM) are removed. Wi-Fi is turned off and then back on, disconnecting you from any network you’re on. The Wi-Fi and Ask to Join Networks settings remain turned on.

To remove VPN settings installed by a configuration profile, go to Settings > General > Profiles & Device Management, select the configuration profile, then tap Remove Profile. This also removes other settings and accounts provided by the profile. See Install or remove configuration profiles on iPhone in this guide.

To remove network settings installed by MDM, go to Settings > General > Profiles & Device Management, select the management, then tap Remove Management. This also removes other settings and certificates provided by MDM. See “Mobile device management (MDM)” in the iOS Deployment Reference.

Thanks.
