I've heard some of the rep say that some other ones not say that however win it arrived from Sprint it said 4G LTE on the box. They claim they were able to add the data plan to the watch but as of this evening I'm still not able to get it to work stand alone and I'm not able to use voice to texting to send text messages on the watch if it's not Bluetooth connected to the phone and within range of the phoneMe too. I heard it's NOT stand alone?...
