Done all the diagnostics I can find. Restarted phone and router. Toggled WiFi calling, WiFi assist, flight mode off and on. Wife’s iphone works fine and can do WiFi calling. Mine can use WiFi but can’t do WiFi calling. Also tried neighbours WiFi. No joy. I’m using an iPhone 15 pro max and BT broadband. No signal where I live so can’t dial 150… Help please. Any advice welcome.
If others can use WiFi-calling on your router, there's your router proven OK.
If your phone isn't working on multiple routers, it points to a device issue. I'm not familiar with Apple, so am not qualified to make any specific suggestions.
