SMS in Satellite Phone Networks

All commercial Satellite phone networks except ACeS fully support SMS. While early Iridium handsets only support incoming SMS but later models can also send them. The price per message varies for the different networks and is usually between 25 and 50 cent per message. Unlike some mobile phone networks there is no extra charge for sending international SMS or to send one to a different satellite phone network. SMS can sometimes be sent from areas where the signal is too poor to make a voice call.

Satellite phone networks usually have a web-based or email-based SMS portals where one can send free SMS to phones on that particular network.
