Iridium two-stage access service – How does it work? The two-stage access platform (PSTN originated dialling) was developed to allow callers without PSTN access to Iridium the ability to call an Iridium subscriber.
On the Iridium activation form it can be indicated if the two-stage access functionality should be activated for the SIMcard.
PINs for the two-stage access platform are assigned by Customer Service and cannot be changed once assigned.
Making a call
The calling party dials an Arizona USA number (+1.480.768.2500) that connects to Iridium’s two-stage access platform located in the Iridium Gateway.
Using automated voice prompts, the calling party enters the Iridium subscriber’s number. (The voice prompts on this platform are in the English language only)
The system will look the number up in the database to see if the subscriber’s number is restricted or unrestricted. If the subscriber has chosen to utilize the PIN option and the subscriber’s number is unrestricted, they will be prompted to enter a valid PIN and will be connected to that subscriber.
