Hello Kaden, thanks for asking! This watch is compatible with Samsung Smartphones, Non-Samsung Android Smartphones (Android OS 5.0 and above RAM 1.5GB and above), iOS 9.0 and above iPhone 5 and above. With this watch you can make phone calls from your wrist. You just need to make sure your smartwatch is connected to your phone through Bluetooth. Once that's set up, you can make as many calls as you want. You can also quickly and easily view incoming messages on your watch and send replies, and you won't even need to take out your phone. ^Elizabeth
