Hello there. Yes, the Galaxy Watch Active Smartphone can be paired with more than Samsung smartphones and even iOS based phones. However, smartphones must run Android 5.0 or higher & RAM 1.5GB above, iOS 9.0 and later, and smartphones iPhone 5 and newer. Even within these conditions, results may vary. I have provided a link to the original specifications as listed on Samsung.com for more information, including an additional link to a list of known compatible devices. https://www.samsung.com/us/mobile/wearables/smartwatches/galaxy-watch-active-40mm-rose-gold-bluetooth-sm-r500nzdaxar/ ^Thomas
