Can I send and receive a Text?

Yes, text/SMS messages can be sent and received on your Iridium satellite phone. Your phone must be on to receive messages.

Texting with a satellite phone is not the same as with a cell phone. The text is NOT an instant text message. The Iridium network will make updates in the network several times during the day to send text messages. To receive a text message you must be outside with your phone powered on and the antenna up with a satellite signal. Once the unit is registered to the satellite your messages will be updated and appear on your screen that you have a message.
