A:AnswerNo this is just gps...BUT it works with your phone when close. The cellular is extra activation that allows you to use it like an individual phone, which is not needed if phone is close.
A:AnswerAs long as it’s under 1 year you will be fine. I myself didn’t purchase the Apple care but I did purchase 2 years Watch warranty from Squaretrade they are a lot better
A:AnswerYes the other day I showered with it and it works perfectly fine. Now if you are looking to do swimming or going into the ocean (deep sea) I don’t think so.
A:AnswerYes it’s compatible in the regard you can start stop or select playlists. At least on GPS model phone has to be nearby. If phone is neat easier for me to control on larger display.
A:AnswerI’m not sure about the co signing part for the credit card. But if you are approved for the credit card the cost amount for the watch will have to be put on the credit card. They have financing you can do with the credit card (if approved) to where you will make “monthly payments” on the credit card for that purchase
A:AnswerIt is not water proof. However, it is water resistant. Example the watch is designed to take only a certain amount of water, like you can shower with it.
