If you have an iridium satellite phone then you select the iridium button which will take you to the iridium text messaging page where you will fill in the rest of the satellite phone number, and type in you satellite text message in the appropriate text box, and hit the send button. The instructions are very much the same on the Inmarsat Network SMS Button.
NOTE:Satellite Text or SMS Messaging can sometimes be not as efficient as making a satellite call, due to the fact that it uses a different part of the satellite gateway. So make sure to check to see if the message has gone though. If you did not recieve an answer then you may want to resend the message. This goes for sending to the satellite phone, and sending from the satellite phone.
