The most common iridium pre-paid card is a 75 minute, 60 day option. However this is based on a use it or lose it basis Iridium allow you 60 days in which to use your 75 minute prepaid, if you do not use all your minutes and you choose not to top up at the end of the 60 days you will lose them.read all about it here
On top of that, with an Iridium prepaid you will also lose your telephone number and the Sim card becomes dead. So although prepaid card can be convenient if you're using your iridium satellite phone only for a very short burst of time and then put it away in the cupboard, it also has issues in regards to its flexibility.
This is on purpose you see a iridium have 66 satellites up in the sky and three on standby and the prepaid option doesn't really give them consistent income to be able to maintain those satellites. So in order to maintain them most prefer online contracts which have a monthly access fee.
However prepaid option does exist with the iridium satellite phone system in Australia but will stop after your two months and or 75 minutes whatever has come first. You may extend the time period before it runs out for a further $50 a month if you have not used your whole 75 minutes, you can extend it from two months to 3 months and continue each month for a further cost of around $50 per month required.
However once you‘re 75 minutes has run out you need to top up your prepaid card if you wish to maintain your current telephone number.
To do this, all you would do is call one 1300 197 600 or go to the satellitephonesales.com.au website and they will top up your card whilst online. This will go directly to your phone matter where you are in the world.
Also within the interface of the iridium 9555, it will tell you how much you have remaining after each cal, l if you're not sure press on the menu bar and scroll down.
However for the short burst user, the Iridium 9555 satellite phone with the prepaid contract is a very easy option when you're not using the phone, and for the rest of the year its dormant and don't want to pay costly monthly access fees needlessly.
