A:AnswerHello Kyle, good question! Samsung has Bluetooth and LTE smart watches. The LTE version can receive calls and messages without being connected to a phone. However, you'll first need to activate service for your watch through the same carrier as your mobile phone. This specific watch model is the Bluetooth version though. ^Elizabeth
A:AnswerHello Fay, good question! If your smart watch has a built-in speaker, you can play music right from your watch. If it doesn't, don't worry! All you need to do is connect Bluetooth headphones. Simply add and remove tracks to build the perfect playlist! If you prefer streaming, you can do that too with a Spotify premium account. ^Elizabeth
