You can change your airtime plan through the PredictWind Satellite Portal. The billing cycle and the best time to change your plan depend on whether you have an Iridium GO exec or Iridium GO!
Iridium GO exec
The billing cycle for an Iridium GO! exec airtime plan runs from the 17th of each month to the 17th of the following month.
If you want your airtime plan change to align with the start of a new billing cycle, make the change on the 16th of the month.
Iridium GO!
The billing cycle for an Iridium GO! airtime plan runs from the 1st to the last day of each calendar month.
If you want your airtime plan change to align with the start of a new billing cycle, make the change on the last day of the previous month.
