A:AnswerThere are Bluetooth only and LTE models of the 42 and 46 watches and several color options for each. Best buy will often put certain colors on sale. I have tiny wrists and have been wearing a 46mm for several years because LTE versions were only available in the huge ones. It was hard to get used to the look, but a pretty band on Amazon helped, but check sizing on all bands.
A:AnswerYes Shells you can. You actually don't even need your phone to be close to it as it has the built in 4gLTE. If you move out of bluetooth range from your phone, the watch then goes into 'Stand Alone' mode, which will allow your watch to still receive all notifications, emails, texts, calls, etc as well as send out texts, calls etc.
A:AnswerYes Maluh, it works independently from the phone without a bluetooth connection to your phone. In fact you can make calls and texts with it in stand alone mode as well.
A:AnswerHi Macca, the Galaxy Watch Smartwatch (42mm) is compatible with a Samsung Smartphone, Non-Samsung Android Smartphone (Android OS 5.0 and above RAM 1.5GB and above), iOS 9.0 and above, and iPhone 5 and above. Thank you for choosing Samsung!
A:AnswerIf Stright Talk offers "Number Sync" with your phone and you have the LTE version of the watch, it should work but that is a question you should ask them directly before you buy one.
