I am looking to have an android wearable (preferable a Smartwatch) with the following specifications:

1) Standalone (must have its own SIM card and should work without a phone connected to it) 2) Net Connectivity. This also means that it is possible to extract the wearable's location using the net (as we can do with a phone). 3) It must be possible to enable Developer Options and install an app via USB (from Android Studio) 4) GPS (This one is optional. Even if we have the above three, I am fine with it) 

The device must have all these three specifications and WORK IN INDIA (that is where I currently am working from). Sorry for asking this here, but I could not find a satisfactory answer while surfing the respective sites and visiting the stores. I request you to help me out with this!
