A:AnswerUnlocked is if you want it to have its own number with your phone company so you can use it independently of your phone. (You don't have to carry your phone everywhere).
GPS uses Bluetooth to connect to your phone. Meaning certain functions won't work if you're away from your phone.
A:AnswerIt can, it's just not authorized in the United States for obvious litigation reasons. It's fairly easy to add on this feature, with a little bit of research on YouTube. I use the feature all the time and it's acurate.
A:AnswerThat is a great question! If the Galaxy Watch4 is Bluetooth, it means that your phone is required to be within range for full functionality. If the device say LTE, you are able to get services through your carrier to be able to leave your phone behind and still experience all of the features the watch has to offer.

A:AnswerIf you are looking for a non-silicone band & like a little bling there are some great choices on Amazon that match this watch exactly. I had purchased 2 bands for my Active 2 pink-gold watch that didn't quite match but it was close. The back came off that watch & Samsung wasn't able to repair it so I got this one, I was so surprised & happy to see that the bands match this one exactly! I always get so many compliments, it makes it an even more beautiful watch! You can find many that don't look cheap or gaudy & have very subtle bling, & there may even be some w/o the bling but that's what I was looking for. This isn't my favorite one but it gives you a good idea of the color match.
A:AnswerIt's suppose to be water resistant up to 40Ft. Don't believe it. My wife had an active 2 which was water resistant and went swimming with it. The watch died in a few months. Called Samsung and was told they don't warranty for water damage even though they advertise water resistant.
A:AnswerYes, the bands I had for my Active 2 fit this one. Samsung seems to make their watches to all use the same size band, which is nice when you upgrade.

A:AnswerJust like most Bluetooth devices, after a couple feet, it'll disconnect. But usually when I charge my phone and walk around my house, it stays connected but right up until about 15ft. But there's walls and stuff in the way too.
A:AnswerHow long the charge lasts will depend on the number of functions you activate. My charge lasts between 24 to 36 hours when I am very active. It records steps, heartbeat, stresss, etc. I even record ECG, all of which uses up the battery.
A:AnswerGreat question, Kate! Being that this is the Bluetooth version of the Galaxy Watch4, no extra fees are required to be able to text and call. All that is needed is a Bluetooth connection. Thank you for asking this question. ^Kayla
A:AnswerThe watch can detect atrial fibrillation if you use the ecg feature. It does not passively monitor, you have to push a button, place a finger on a sensor, and wait for 30 seconds.
