A:AnswerFor most smart watches you don't need a carrier, just a phone. I think there is only one smart watch that has a LTE radio built in so it can make and receive calls.
This will work with most Android phones (Android 4.3 or higher).
A:AnswerThe range is really good. I can leave my phone a room or two away and still get notifications on my watch. It also is able to communicate through WiFi in your home which give you the ability to get and respond to most notifications.
A:AnswerThe Samsung Glaxy Stardust is an Android 4.3 model and, luckily, the LG Urbanes should supports Android phones 4.3 and above. Try it at a demo watch if you havent had to chance yet before purchase.
