This Calculator applies to the TG - Pay Per Message (PPM) plan for 'low use' assets that do not send many records.

Note: a 'Message' corresponds to each individual record, or a line of Telemetry in Telematics Guru (Assets -> Telemetry).

Some devices may log GPS points while moving, and upload in batches (e.g. the Oyster2). Note it is the number of logs, uploads, that determines the message count.

Whilst there are no fees for going over a message cap, devices must be configured in OEM server to limit the number of messages they send to TG. A device sending many messages will attract a large fee (test this in the calculator to see)
