Follow the steps below if you are unable to place a call to an Iridium subscriber or receive a call on your Iridium device using Two-Stage Dialing.

In order to place a call to an Iridium subscriber or receive a call on your Iridium device using Two-Stage Dialing, the subscriber must place an outbound call and successfully establish the call for the very first time. Once this has been done, the Iridium subscriber line will be registered for Two-Stage Dialing and calls will be routed correctly.

NOTE: Due to the Iridium service outage that occured on October 20, 2016, all Two-Stage Dialing subscriber registrations were cancelled. To re-instate the Two-Stage Dialing registration an outbound call must be established.

A call can be placed free of charge by dialing Iridium's automated test number at +1-480-752-5105.

If an outbound call has been placed and Two-Stage Dialing is still not working, please contact Roadpost Technical Support at 1-888-622-7368 or +1-416-253-6008 so we can check the provisioning of your subscriber line.
