You buy the airtime that’s valid for a set period, activate it, and top up when needed. You also get full global coverage, even at the poles, over oceans, or in remote regions, as long as your phone has a clear view of the sky.

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 30 day extension before the original expiry date.

If the validity is not extended then your SIM card will expire and become unusable. Any minutes remaining will be lost and your SIM will enter a 270 day grace period in which you may 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 this 270 day 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.

Prématuré maybe but I’m sure I’ll be happy with it

Bought for a trip to the Pamir Mountains. It’s going to be very useful.

GTC Iridium Sat Phone Prepaid SIMs

Easy to buy, easy to activate, easy to install. The simplest way to have peace of mind when relying on Iridium as a reliable backup when in remote areas without mobile phone signal coverage - so potentially a lifesaver in the event of a real emergency.
