Calling from the aircraft works differently from a normal phone. Every call starts with **00**, whether you are calling another satellite phone or an ordinary landline or mobile. ## Calling another Iridium satellite phone **00 - 8816 - XXXXXXXX** ## Calling an ordinary landline or mobile **00 - country code - number** Example: For the United States and Canada **00 - 1 - XXX - XXX - XXXX** The country code is always the code for the country you are **calling**, not the country you are flying over. Every country has its own code, and your telephone provider or any international dialing reference can confirm it. ## To check that dialing is working Call the Iridium test line: **00 - 881631110006** If the test line connects, the unit and the airtime are working. Countries where calls to satellite phones are restricted Calls to Iridium numbers are restricted or blocked in the following countries: Bangladesh, Chad, China, Cuba, India, Libya, Myanmar, Nigeria, North Korea, Russia, Sri Lanka and Sudan. Iridium phones are permitted in Russia, but they must be specially registered. ## Facing an issue with calling?
