Why do I need an M2M data plan with the Modemulator?

The Modemulator emulates the behavior of an analog modem, but actually connects over a cellular
network instead of the legacy Public Switched Telephone Network (PSTN). Any device that connects to a
cellular network must subscribe to a cellular service plan.
