Question

WiFi calling sends all calls to voicemail

All incoming calls are being sent to voicemail. My phone doesn’t ring at all. I have an iPhone. Call Forwarding is off, Focus is off, Live Voicemail is off, Silence Unknown Callers is off, but WiFi Calling is on. iPhone updated to latest iOS, but didn’t help. Adjusting the ringing timer via shortcode didn’t work either. Restarting the iPhone, or enabling then disabling Airplane Mode solves the issue, but not permanently. What works permanently is if WiFi Calling is switched off. Why is this the case? What is iD Mobile doing to fix this issue? Me and both my parents are on iD Mobile, and I’m the reason they switched to iD Mobile from O2 with whom they never experienced the issue. Now I’m embarrassed because they keep missing important calls such as from their GPs when they’re at home. And isn’t WiFi calling supposed to help you stay connected for when the mobile signal is weak?

    Hi ​@Buttons Up ,

     

    I’m really sorry to hear you’re experiencing issues with Wi-Fi Calling. Let’s try a few steps that often resolve this:
    Troubleshooting Steps

    -Restart your iPhone – This refreshes network settings.
    -Toggle Wi-Fi Calling Off and On – Go to Settings > Mobile Data > Wi-Fi Calling.
    -Reset Network Settings – Settings > General > Transfer or Reset iPhone > Reset > Reset Network Settings.
    -Check Wi-Fi Stability – Make sure your Wi-Fi signal is strong and stable.
    -Update Carrier Settings – Go to Settings > General > About and wait for any update prompt.
    -Test with Wi-Fi Calling Off – If calls work fine without Wi-Fi Calling, keep it off temporarily until the fix is applied.

     

    You can also find more detailed guidance on our iD Mobile website if needed.

    We have kept WiFi Calling off for now as that had solved the issue for us. However, iD Mobile is yet to provide a permanent solution that will work even if WiFi Calling is on.

    Suffering from exactly the same issue here. It seems to work on other WiFi networks so I suspect it's a home Internet problem. Another device on O2 works fine for WiFi calling on the same WiFi.

    Hi ​@MatthewSt,

     

    We're sorry to hear about the issues you've been experiencing with your coverage.
     
    We appreciate how frustrating it can be when the service you're receiving doesn't match what you'd expect, particularly if the coverage checker is showing strong coverage in the areas where you're having problems.
     
    As a first step, we'd recommend checking the coverage checker again to see if there are any reported issues or maintenance affecting the locations concerned: https://www.idmobile.co.uk/help-and-support/coverage 
     
    If the issue persists, please contact our Live Chat team so they can investigate further and check whether there are any network-related issues affecting your service: https://www.idmobile.co.uk/live-chat 
     
    They'll be able to review your account and discuss any available options based on the outcome of their investigation.
     
    Regards,
