Sending SMS text messages to Iridium phones from cellphones can be problematic and may incur higher costs than the standard text charges. The message sender will need to contact their carrier to verify what the charge would be for texting to a Satellite phone.

A more reliable alternative is to send text messages from Iridium’s website. It’s quick and easy – and totally FREE of charge:

– Visit
– Enter the Iridium phone number (8816 ???? ????)
– Type the message in the “Message” box (maximum 160 characters)
– Click “Send Message”

Please be advised that text messaging is not a guaranteed service and messages can be delayed, corrupted, or fail to send on occasion. If a message is urgent or critical, we would always recommend calling rather than texting.
