Frequently asked questions

You can add a Samsung Galaxy Watch LTE when you take out a new contract with us, or you can add it to your existing account. To share your allowance between your Samsung phone and Samsung Watch LTE, you’ll need Smartwatch Pairing.

Three currently only supports Samsung Galaxy Watch6, Watch6 Classic, Watch5 and Watch5 Pro. We don’t support any previous models.

The benefit of having a Samsung Watch LTE rather than Bluetooth, is that you can call, text, and use data without the need for your phone to be nearby. The Samsung Watch LTE will use the same airtime plan as your phone, as long as you have Smartwatch Pairing.

A Samsung Watch LTE will automatically connect to the nearest Wi-Fi so that you can call and text or use data. But if you want to be able to leave your phone at home and still enjoy this feature, you need our Smartwatch Pairing Plan.

You don’t need a separate SIM card for your Samsung Watch, because it has a built-in eSIM. If you buy our Smartwatch Pairing Plan you can then connect your Samsung Watch to our network and pair it with your phone.

How will my Samsung Watch connect to the Three network?

With the built-in eSIM and our Smartwatch Pairing Plan, your Samsung Galaxy LTE will connect to the network the same way your phone does. This means you can leave your phone at home and still be able to make calls and send messages.
