I live in North Wales, but every time I try and ring the 111 number from my mobile, I'm being told that the service isn't available in my area. Why is that?

If the Wi-Fi Calling feature is enabled on your mobile phone, it could be interfering with your location when trying to ring the 111 service. To ensure that we can determine your correct location, you will need to turn off Wi-Fi Calling before dialing. To turn off Wi-Fi Calling, you’ll need to change the settings in your phone. The process is slightly different for each phone, so please contact your service provider for help with how to do this.
