A:Answerapproximately 15 feet. however depending on the structure and surroundings it may work further. I left my phone in the car for a Dr. appointment and well over 100 feet away it worked - but only a window was separating me from the direct line to the phone.
A:AnswerYou can download the Spotify app on the watch. However you can not stream music through the watch itself. You can however connect a speaker or headphones to the watch itself via Bluetooth and still leave your phone in the locker.
A:AnswerYes, but you would only need a GPS version, not a GPS + Cellular model if you are not using a separate SIM card and simply connecting it to the phone via Bluetooth.
A:AnswerNo. No it cannot. Apple Watch relies on the content and information on an iPhone and for the connection to work, both ends need to be made by Apple. Apple encrypts much of the information shared between iPhone and Apple Watch, so it ends up being more than just a simple Bluetooth pairing.
A:AnswerThis is probably not very helpful but I would suggest that you inquire from US Cellular. I do not know but a guess would be if it works on your I phone it will work with your watch,
