What is Wi-Fi Calling?

Wi-Fi Calling is a new iD service that lets you make and take calls using a Wi-Fi network. You can also send text messages through the same Wi-Fi network.

Indoor blackspots can stop you getting connected, but with Wi-Fi Calling, that's not a problem. It gives you clearer calls, in more places than ever before.

How do I get Wi-Fi Calling?

1. Make sure you have access to Wi-Fi

Wi-Fi calling will work when you are unable to connect to either a 3G or 4G network and have a minimum of 2MB speed.

2. Check that your phone is compatible

3. Make sure your software is up to date.

Update your phone's software (if needed) and accept the latest carrier settings (for iPhone users). Then your Wi-Fi Calling is good to go. You may need to switch on Wi-Fi Calling in your phone settings.

* iPhone users will have to install the latest software (iOs 11.2)


Improved coverage

Wi-Fi Calling uses Wi-Fi to smash through indoor blackspots, so you'll be able to make phone calls in more places.


4G Calling lets you make and take calls over a 4G network. Wi-Fi Calling, on the other hand, lets you make and take calling through a wireless internet connection.

Wi-Fi Calling comes out of your monthly allowance of minutes. If you haven't got any minutes left, you'll be charged at our usual out-of-plan rates.

You'll also be charged at our out-of-plan rates if you make a call that's not covered by your monthly allowance of minutes. These include international calls, or premium calls such as chat lines and TV competitions.

No. It is only for domestic use.

To get Wi-Fi Calling you need to make sure your software is up to date. We recommend that you backup your phone's memory before you do any software updates - just to make sure everything's safe.

We're adding new smartphones all the time. Keep an eye on this page, because we'll update it every time a new handset gets Wi-Fi Calling.

To enable Wi-Fi Calling on a compatible Apple handset, follow these steps:

  1. Make sure your device is connected to a Wi-Fi or cellular network.
  2. Upgrade to iOS 11.2
  3. Accept new carrier settings
  4. Go to settings > Mobile data > Wi-Fi calling
  5. To check your carrier settings, simply tap Settings > General > About while using an iD SIM. The carrier field should display iD 31.1 or greater.
