In addition, it is necessary to activate the very possibility of dialing to subscriber numbers with debiting the price of calls from the personal accounts of Iridium subscribers, which the service provider can do either immediately with the purchase of a satellite telephone and activation of airtime packages, possibly later on requests from subscribers.

To start using this service, you need to purchase a dial-up card with the required denomination, after which you will be informed of the PIN code required to access the gateway. After that, you can call the numbers Iridium subscribers-networks.

There are 2 options for dialing to Iridium subscriber numbers at their expense:

1) First option: Assigning a dedicated phone number to an Iridium subscriber + subsequent forwarding to a real one telephone number any subscriber of the Iridium satellite network for incoming calls.

This method is considered faster in terms of the period of time required to establish communications with the subscriber, but this option implies the presence of a monthly permanent payment for the use of a dedicated telephone number, as well as payment per minute for incoming calls, followed by debiting these funds from the personal account of a real Iridium subscriber.

The cost of one minute of a call for callers using such a dial-up card, in this case, will be almost negligible, amounting to a few cents.

2) Second option: Calls to satellite Iridium phones via US gateway.

This method will require a slightly longer period of time to establish a strong connection with the Iridium subscriber, since for this it is necessary to first establish a connection with the US gateway gateway. After the connection with the gateway is established, the caller is invited to dial the 12-digit number of the real subscriber of the Iridium network and remain on the line until the connection is established with the desired subscriber. If users' phones are in pulse mode, before dialing Iridium subscribers, it will be necessary to switch the tone mode by pressing the star button.

For every 60 seconds of a conversation, a certain amount will be debited from the account of the called subscriber. The cost of one minute of a call for callers using such a dial-up card, in this case, will be almost negligible, amounting to a few cents.

As a result, the use of one of the above two methods allows the caller to make calls to telephone sets and terminals of the Iridium satellite network almost free of charge, and the called subscribers will pay quite reasonable amounts compared to the price of calls from PSTN telephone networks, an alternative Internet telephony network, cellular mobile communication networks.
