A:AnswerYes. You can initiate the call on your Gear Sport either manually through the contacts on your watch or by using S voice. You will then have to switch over to your cell phone to continue communication as the watch does not have a built in speaker.
A:AnswerThere is no Lte version, only wifi. It does not have to be connected to a phone to work unless you want to receive notifications then it does need to be connected via Bluetooth or at least on the same wifi network.
A:AnswerOnly of it is cellular capable, so no. But you can talk using it within range of your phone as long as you have it paired with a headset, earbuds,speaker, etc
A:AnswerYou can make and receive calls with the watch but you can't talk through the watch itself. You have to have your phone out and will have to use your phone for the calls. The only thing you can do on the watch is chose to answer it or ignore it. The only thing you can do is reply to text messages.
