I've been struggling to enable wifi calling on the galaxy s26, and on further inspection it isn't on the approved phones list for wifi calling from ID mobile. Why is this?

Hi @Mikerob,

Thank you for reaching out.

We’re sorry to hear that both lines are experiencing issues with the service at home and work, and we understand how frustrating this must be, especially after trying the troubleshooting steps already available through the Help Hub.

As you have mentioned that Wi-Fi Calling is also not working, please try the following steps:

1. Restart both handsets

Switch both iPhones off completely.
Wait a few minutes.
Turn them back on and test the service again.

2. Refresh the network connection

Turn Airplane Mode ON.
Leave it on for around 60 seconds.
Turn Airplane Mode OFF.
Allow the handset time to reconnect to the network.

3. Check Mobile Data settings

On both iPhones:

Go to Settings
Select Mobile Service
Ensure Mobile Data is switched ON
Select Mobile Data Options
Check that the correct settings are enabled

4. Check network selection

Go to Settings
Select Mobile Service
Select Network Selection
Turn Automatic OFF
Wait for the available networks to appear
Select iD Mobile / Three UK
Turn Automatic back ON

5. Set the handset to 4G
Where 5G coverage is limited, using 4G can provide a more stable connection.

Open Settings
Select Mobile Service
Tap Voice & Data
Select 4G

6. Check Wi-Fi Calling
Please ensure:

Open Settings
Select Mobile Service
Tap Wi-Fi Calling
Ensure Wi-Fi Calling on This iPhone is enabled

If Wi-Fi Calling still does not work:

Restart your router.
Test on another Wi-Fi connection if possible.
Ensure your iPhone software is fully up to date.

7. Reset network settings (if required)

Please note this will remove saved Wi-Fi passwords and Bluetooth connections.

Go to Settings
Select General
Tap Transfer or Reset iPhone
Select Reset
Choose Reset Network Settings

If the issue continues after completing these steps, please contact us via Live Chat or send us a direct message through our social media channels so we can review the account and investigate this further.
