Review: Doesn't connect to Bluetooth - Love it
Review: Kind of feel ripped off right now - You have to pay 35 bucks a month to connect to the phone. You also have to pay a monthly fee to make a phone call or write a text using the watch. It would probably be cheaper to open another phone line. It will connect for my phone numbers. But that it. I cant call the numbers on my watch. I have to buy a sims card and pay for a service. If I get it to work I will charge this post.
