What you described sounds to me like slate. It doesn't have maps or a sim. It doesn't even have a digital dashboard at all[0].

I barely looked it up so I'm no expert, but that's what I'm interpreting from their site.

Again, not having a feature doesn't mean they don't send telemetry back. They can be stripped down AND steal my privacy. In fact, I expect them to considering the backers.
