@Stev35555 Have a look at THIS and click the check service status tab. WiFi calling should work still even if the cellular network is down. If WiFi calling isn’t working also it could be a SIM card fault or possibly a device fault. Have you tried just restarting the device ?
Can you try a different EE sim in your device? Or is anyone else with you on EE also having this same issue?
To contact EE Customer Services dial 150 From your EE mobile or 0800 956 6000 from any other phone.
