If you do not want to sign up to a monthly contract then Iridium also offer vouchers to work on a pay as you go basis.
Please note if you have an existing standard Iridium SIM you will not be able to use this in the Iridium GO!
The lowest validity we offer for our pre-paid Iridium GO! airtime vouchers is 180 days perfect for a short trip. You can also extend the vouchers we offer for a further 30 days by purchasing one of our 30 Day Prepaid Airtime Validity Extension vouchers.
