Previously, a Samsung smartphone has been a strict requirement, even if you've been settling up using the device on your wrist. With the Gear S3 duo, though, all you need is a handset running Android 4.4 KitKat or above for Samsung Pay to work. To be clear, Samsung isn't releasing its mobile payment app far and wide, squaring up to Android Pay in the process. Instead, you manage your Samsung Pay account within the Samsung Gear app.

Opening the door to other Android handsets makes a lot of a sense, as it means potential customers without a Samsung smartphone won't be put off by missing out on one of the wearables' key features. And the news couldn't come at a better time. The Gear S3 Classic and Frontier have been available in South Korea for a week, but today they've launched in several other countries across the world, including in the US and UK.

Whether it's the sleeker S3 Classic or the busier, more rugged S3 Frontier you're after, both Tizen-powered wearables start at $350/£349. Various mobile carriers are also on hand to sell you the device, and you might want to check those deals out first if you plan to make use of the Frontier version's built-in LTE radio.
