No, the BPN server is a server side service that persistently recieves APNs to forward to the phone (that don't contain the message data) since unlike iPhones, Android phones can't persistently check for APNs (at least that's what I understood from the announcement article). AIUI that's what you're paying for. But that wouldn't explain why sending is broken.

The How It Works article is clear that BPNs is only used to serve push to your phone when the app isn't running. Disabling it would not cause send/receive failures.

If you check the How it Works post, they do show the Beeper Push Notification Service running in the cloud [1] to intercept 'new message available' APNs and then notify the Android device a new message is available.

Only required when Mini isn't running.

If it were purely client based, why did I leave to log in with Google to something then?
