To anyone's interested in a SIM, there's a kickstarter selling a 5$ SIM with 6 months (6MB) of data included, and ~1$/1MB/1month plans: https://www.kickstarter.com/projects/konekt/konekt-dash-cellular-dev-kit-free-global-data-plan

On an slightly unrelated note, a few days ago I had a chat with Mark about the new hardware version. I have some work to do this week but after that I'll get some ideas together and post them so we can discuss.

Regards,
