Android tablet with no baseband, e.g. a Nexus 9 for example. Freedom pop sells such a device permissions: Android Marshmallow has this bog standard, no root needed, so might have to watch to make sure it's available on whatever device you choose. voip: google voice/hangouts can make this possible, also skype, hangouts, and a number of others. VPN: basically anything android compatible. It's not a terribly convenient thing to initially setup but it's not difficult either anymore, I actually did this for a few months when I broke my phone and just decided to go all IP instead of buying a new phone (had the tablet, and the hotspot device, previous phone didn't have data). It worked well enough in the Los Angeles area, but outside a city it was basically non-functional. The other points about 911 and such are bigger issues than this.
