I wish that there was some kind of a lifetime connectivity plan. You buy a modem with a one-time fee, it has a unique ID, and you get to send/receive data at a low bit rate for the life of the modem (or until the satellite service is discontinued).
IMO that would make IoT devices a lot more attractive. The device works for years and you never even have to worry about setting up an account to pay a bill.
Checkout https://www.particle.io/, they have a pretty nice free plan that includes cellular data
If you're willing to be in the footprint of mobile phone operators, a mvno like this [1] can get you to pennies per MB, pay for use. If the T-Mobile/Starlink plan works out, you might even get LTE via satellite.
There definitely should be a lot of market for for such an extremely low-end kind of connectivity, with small hourly updates. Weather / water / fire monitoring stations, maybe even pipelines (as a fallback for the usual wires / fiber), a backup emergency link for trucks / cars / watercraft / small aircraft / drones. The built-in GPS is extra helpful.
No, this may be huge.
