Smartwatch Pairing

Pair your smartwatch with your phone to put all the power on your wrist and always stay connected.

With our Smartwatch Pairing Plan, you can connect your smartwatch to your phone on Three and share your plan allowances between the two devices.

Then you can call, text and use data on the move, all without your phone.

The benefits of smartwatch pairing

If you’re at the gym or on a run – or if you’ve accidentally left your phone at home – you won’t miss any important calls, texts or notifications.

Share your allowance

Share your phone allowance with your smartwatch to make calls, send texts and use data when you’re out and about.

Your music, your way

Forget about downloading playlists. With our pairing plan, you can stream music from your watch using your data allowance.
