Can you give a run-down what's involved in getting service? Would I need to register with you and get an app or something? Which devices are supported? Do I need rooted device?
You can just install the app on a normal device and subscribe to the service on first run. For PGPP Relay, almost any Android device (and maybe even Chromebooks) works fine. For PGPP Mobile plans, you'd need an eSIM capable device (e.g. Pixel 4 or newer or Samsung S22).
