Need to answer calls from phone on my tablet while no internet will be available, any ideas?

[Android Central Question]

I've looked an apps like teamviewer and others, but as soon as I leave the house and my wifi connection is lost they don't work. My tablet is a note 10.1 running 4.1 and it's mounted on my dash, Everything else works great but I'd like to be able to answer calls on the tablet screen without having to grab my phone.
