Unfortunately, Telstra customers cannot use the Iridium website to send messages to satellite phones with Telstra MSISDNs, as our messaging external box only supports 8816 and 8817 country codes. We recommend using Telstra's web-based SMS tool, which routes messages to Telstra’s SMSC within the Telstra network.

Ensure that you are entering a 12-digit number in this format 8816XXXXXXXX. Do not add any spaces or dashes. If you are still having problems, emails can be sent to Iridium phones by entering the Iridium phone number into the following address: 8816XXXXXXXX@msg.iridium.com
I am unable to send SMS messages from my phone?
The most common reason why a user experiences problems with sending/receiving SMS messages is likley caused by the Service Center number not being programmed into the handset. Verify that the Service Center Number is programmed correctly, with the preceeding "00" or + (00881662900005 or +881662900005). Additional information can also be found in the user manual.
Why can't I receive SMS messages on my Iridium handset?
Check to ensure that the folder capacity (outgoing, incoming and draft) has not exceeded 30 messages. Also, that your phone is registered. To test registration on the phone, Iridium has created a test number; 001-480-752-5105. There are no charges for performing this test. Additional information on SMS messaging service can be found in the user manual, section 7, titled "Using the messages menu".
