Using A '90s Satellite Phone On The Iridium Network

Recently a viewer sent me this old Iridium phone, which uses a network of low-Earth-orbit satellites to make calls. This is a system from the 1990s that still operates today!

Thanks to GTC for sponsoring this video and supplying a SIM card for me to use. You can find them at https://gtc.co.uk/ in the UK or https://osat.com/ in the US.
And you can use the code "Hello10" for $10 off your order.
