Galaxy Z flip 4

Wi fi calling not working, even though it's turned on. Any suggestions please

@debbiej: To troubleshoot the issue, please try restarting your Galaxy Z Flip4, and reset your router by unplugging at the wall for 30 seconds, then plugging it back in. Following these steps, please try connecting to a web based app such as Samsung Internet, and visit a reputable website to make sure that your Wi-Fi connection is stable. Please note that you must have a registered network SIM card inserted in your device in order for Wi-Fi Calling to function as expected. 

If the issue persists, please can you clarify what happens when you attempt to make a call with Wi-Fi Calling enabled? Do you get any error messages or notifications? Furthermore, do you have a strong mobile network connection, as this may be overriding the Wi-Fi Calling feature?

Thankyou. I live in an area with no mobile signal. So I can't make calls or send text without Wi Fi calling. It has worked all the time until today

Put the phone into Flight Mode to see if this pushes Calling Over Wi-Fi to take over calls.

If no luck then also speak with your Networks Customer Services to check the feature is still provisioned on your account @debbiej
