I just got this watch and got it set up. When I shut the phone bluetooth off it goes into standalone mode with Verizon. When I call my number both the watch and the phone ring at the same time, so at least the phone number portion of numbershare is working. However, texts only go to my phone, not to the watch. Texts sent and received from the watch only show up as the watches assigned number.  I was hoping at the very least the wearable app could push texts forward to the watch, but doesn't seem to be the case. A very knowledgeable verizon rep I spoke to said that they've had extensive discussions with Samsung and it looks like sms sharing between lte watch and phone will not work with the galaxy watch. Seriously considering returning this and getting on old gear s3 lte which is supposed to definitely have this function. What was Samsung thinking?!
