Review on 📲 4G Smart Watch: Android 7.1, 2.86 Inch Screen, 1GB+16GB, 5MP Camera, 2700mAh Battery - Perfect Smartwatch for Men! by Mark Lodge

This seller will not tell the truth about specific problems, the watch is in the hk browser , and the sim card does not connect, it says network status is unavailable, please try again later. Bluetooth calls don't work, messages don't work. I had less than 24 hours when I requested a refund, a Revain rep and a Revain tech told me the seller said the device wasn't designed to make phone calls, when I messaged they said it could lie, i wore it you stay away from the seller.
