This communication module in our roadster was the best investment we ever did for our roadster. What did it cost us? The module box cost us just less than $ 100. The price for the telephone GPS card is a prepaid card for $ 8.33 per month. Actually you would have to buy for $ 100 in advance for 12 month use.
The best function of this module is that in case the charge is disconnected the module will sent an SMS to my cell phone to inform me that the charge was interrupted. This gives me the chance to reconnect the electric power to the roadster. So you do not have to wait and permanently check your power connection.

Here is the description what the OVMS group is writing about the module.

The OVMS (Open Vehicle Monitoring System) team is a group of enthusiasts who are developing a means to remotely communicate with our cars, and are having fun while doing it.
