Questions & Answers
new to smart watches, what is the difference between the choices "unlocked" or GPS?
Answered by SamsungThat is a great question, Traci! The Unlocked means that you are able to add services through your carrier to use all of the features without your phone being present. If it is described as Bluetooth or GPS, it means that the mobile device needs to stay within range for all features to be used. Thank you for taking the time to ask this question. ^Kayla

C an you answer calls on it
Answered by BrownieIf you buy the watch with its own plan through your carrier. I have Verizon so we added it to our mobile plan for 9.99 month. That way you can use the watch without having your phone with you. Great for going on a run or if your phone dies you still have watch as an option. It will ring when you have a phone call even if your phone is not with you.
So, battery life is missing from the specs. I'm guessing it's not great? I can't find it here, or on Samsung's site for the 40MM LTE version. Anyone?
Answered by SashaBattery life is the worst. I previously had the Watch Active 2 and could go approximately 1-2 days before having to charge it again. It’s only 2 months old and the battery life gets worse every day. I literally charged this watch 10 hours ago and just had to put it on the charger because the battery was low.
