Send a message to an Iridium satellite phone
The Iridium 9555 and Iridium 9575 satellite telephones can receive SMS, small email and web messages of up to 160 characters each. The Iridium user can reply to your mobile's number via SMS, or to your email address.
You may send a maximum of 160 characters. Any messages in excess of 160 characters will be truncated.
To email an Iridium, use the 8816xxxxxxxx@msg.iridium.com without the + sign, for example:

The email message is the first 120 characters in the email body (not the email subject). Your own email address counts as part of of the 120 character allowance.
