I'm still trying to figure out how they do this - a flat fee for unlimited data??
All I can come up with is they've negotiated bulk unlimited accounts with providers in each country. Assume the rate runs about $100 USD per account per device or SIM, they would need to have each unit rented in the field for roughly 7 days a month to break even.
