A:AnswerCellular cannot be added to this watch, as it is only a GPS model with no cellular capabilities. A good way to compare the two would be most cellular editions have a red dot on the crown, whereas the GPS only watch doesn't.
A:AnswerNot on the GPS only! If you had the cellular, then it would. I have the GPS only and I can’t get super far from my phone or it will disconnect.
A:AnswerThe faces can be changed -
digital time (like 10:05) over custom background pictures, colors, or motion scenes/characters. Or a variety of analog face styles and colors - more limited than the digital choices.
A:AnswerIt all depends on what kind of watch you bought whether the one that allows both wifi+cellular or just wifi alone. So check your purchase history or the box that it came in and it should give you more information as to whether your watch has cellular data or not.
A:AnswerThe Apple iPhone watches do not normally come with an extra band unless it was a promotional deal. I believe there was a promotional deal during Black Friday regarding and extra band. Regarding the charger, that is something that you should take back and then receive your charger. To my knowledge, all iPhone watchers come with a charger.
