Iridium Prepaid Service cards are the best solution if you're working on short term or seasonal projects and you know how much airtime you'll need. There are no contracts, no activation fees and no monthly bills. You'll also receive alerts when you're running low on minutes or when your card is going to expire so you won't lose the time you have paid for.
Postpaid Iridium Service subscriptions are a great option if you use a satellite phone on a regular basis or for a prolonged span of time. You'll get detailed call records each month and the convenience of uninterrupted service without having to manage usage and airtime online. You'll pay a monthly or annual service fee and you'll get the option to choose from competitive airtime bundles and pooled minutes between multiple users.
