How does the Iridium GO billing work?
The airtime plans are monthly with some rules.
You cannot activate and deactivate in the first month.
The first month is prorated, thereafter you are charged per Calendar month.
The most popular Iridium GO Plan is the Unlimited Plan. On this plan, you can make unlimited data connections/minutes to receive unlimited email & weather data, or data on any other certified Iridium GO App. There will be no additional data charges to the monthly plan charge.
You can make unlimited SMS text messages to any mobile in the world.
The Unlimited plan has a free allowance of 150 minutes of voice calling to any landline or mobile in the world.
Satellite phone calls are not included in this allowance.
When you use the PredictWind Offshore App connected to the Iridium GO, it will display how many voice minutes you have used.
