Just a fyi, the Verizon app works well with my Gear S2.
Yes, as far as I know. There's a companion app for MT that you need to install on your phone, so I gotta imagine that the phone needs to be on in order for the companion app to recognize the incoming text and push it to your tablet. I don't really ever power off my phone for extended periods of time other than when I go to the movies or someplace else that a cell phone would be inappropriate.Does Mightytext require the phone to be on? You know that you can use Verizon's Message+ and text from a wifi tablet from anywhere even if you leave your phone at home or off.
