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,
A:AnswerI have one Planatronics, and threeJabra Bluetooth headsets. It depends on what version of Bluetooth you are using what features work and how well they work as well as how complex you have made your connections. Is something stealing the connect command for example. I have one Jabra earpiece that has a monogamous relationship to my watch. When my watch rings I pick it up and open it and instantly I am talking. Some of it has to do with the processor speed of my new Apple Watch Series 4. On the other hand my desk Jabra is hooked to my laptop and it never seems to get the connect quite right. The Planatronics is so old of tech that it really is a wonder it works at all, and it normally gets left home. If you are having issues with phone and watch conflicts turn off your phone or tell it to forget the devise.
A:AnswerYes, unfortunately Verizon and Att do NOT use the same cellular bands and they are not compatible with one another. However, you should be able to get a replacement within 14 days for the correct model with the purchase receipt.
A:AnswerYou have to have an iPhone to set up the watch, for updates and new apps. You can use the watch only when exercising and using GPS and, if you have the cellular model, for making calls. The watch and the iPhone are designed to work together and they constantly synch.
