Better question would be how can I piggy back off this cell connection to turn my bike into a WiFi hotspot
Without any googling I would guess that it uses the cell connection to send data to the app through the Harley cloud like charging status Security Status, Tamper Notifications etc. This is all new to me though so I could be wrong. My Ford Maverick has it too and it works great I can remote start the truck from anywhere and remote lock/unlock it see how much fuel is in it and tire pressures etc all through the free Ford App.
