How long are the iridium 9555 airtime contracts?

 Iridium will always be the airtime supplier in the sense that it is their group of 66 satellites and their airtime that is being used.

Then Telstra and Satellite phones sales are providers of this airtime to the public as Iridium simply deal with their dealer network.

The major differences between nearly all Iridium satellite dealers is that they have a 24 month contract with their Iridium 9555 satellite phone handset deals.

At Satellite phone sales we listened to you, the consumer and realised you wanted both pre paid sim options as well as 12 month contracts. So we created a 12 month contract which allows you to have the freedom to extend rather than enforcing a 24 month non flexible contract.
