Review: Big watch! Awesome Android phone watch. - When I got this watch I was awed on how big it was both the phone and the wrist strap. The phone is solid and the strap is made to last. Besides being a phone it's also a fitness watch. As any device there is a learning curb but it's a no brainer to learn as it's intuitive. Included in the box is a charging dock, mini screw driver, two screen protectors and a simple instruction. The screen is bright enough with an awesome screen/colors and responsive and it has a camera. I placed my phone's nano SIM card and the settings worked automatically (TMobile) though it took awhile for the watch to respond to the network and the APN settings were correct. There are multiple networks that are compatible with it. A warning though, the screws that holds the SIM card cover is miniscule and can easily be lost when you're not careful. I recommend placing a white paper underneath the phone in case the screws falls off the cover so you can easily see it. Since the OS is Android 7.7.1 some apps from the play store will not work such as Netflix but it works with FB Messenger and YouTube Music. Since RAM is limited you have to choose wisely which apps you can load. When I first got the watch the font was small but there are size options under settings. This is an standalone phone and it's not like a Samsung watch in which you can pair with a Samsung phone to make and receive phone calls. I'm still exploring it's capability and so far it's positive. It's a shrunken Android phone or tablet.
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.
