Iridium Sat Phone Top-Ups
Top-ups for your active Iridium satellite phone prepaid SIM card.
Scroll down for information about Iridium's revised SIM card reactivation process.
Iridium SIM cards start with zero balance and validity. Choose the option appropriate for your needs and you can then extend at a later date if you need to. SIM card validity can be extended by purchasing another prepaid voucher or a 30-day extension before the original expiry date.
If the validity period is not extended, your SIM card will expire and become unusable. Any minutes remaining will be lost and your SIM will enter a 270-day grace period. Within this time, you can reactivate the SIM by adding a new voucher, however, the original balance will be lost and will not be added to the new balance.
After the grace period has ended, the SIM will automatically deactivate meaning that you will need to purchase a new Iridium airtime SIM Card and pre-paid voucher. Reactivating a deactivated card incurs the Reactivation Only charge below plus the cost of a new airtime voucher.
If you did not originally purchase your SIM card from Global Telesat Communications we will be unable to add credit to your card. However, Iridium SIM cards are free of charge so why not order a SIM card from us as well? Iridium Sat Phone Prepaid SIMs >
Revised Iridium SIM Reactivation Process
In order to be more sustainable by reducing SIM card waste and physical shipments, and to get customers activated onto the Iridium network more quickly, Iridium has redeveloped its SIM card reactivation process. This new streamlined approach also means you can release your Iridium SIM card for a fraction of the previous cost.
