Eliminate International Texting Fees for Good Iridium is treated as a foreign country by all cellular carriers. These carriers can charge US$15 per month or US$0.50 per message, and sometimes even apply overage rates when sending SMS messages to an Iridium phone. OneMessage users do NOT need to activate international texting service on their smartphone to send texts. With OneMessage, you get the maximum value from your satellite phone connection economically, while using an interface that feels intuitive and familiar to keep in touch no matter where you travel.
