https://community.three.co.uk/t5/Network/Wifi-calling-not-working-with-talktalk-broadband/m-p/65990#M14527 <P>I have just changed from BT Broadband to full fibre broadband with Talktalk. My S25 ultra and my wife's S23 ultra now don't work with WiFi calling. The only thing that has changed is the router. Can anyone suggest a solution to this issue.
