What I'm wondering is how long it will be before we see a similar device/service for Starlink's network.
For low bandwidth applications like Swarm, perhaps a cheap 4g breakout board would work out-of-the-box with the right plan.
Also, the Starlink modems need a huge amount of power compared to the Swarm network, not really a similar application.
