Comparing OneMessage to the standard Iridium Messaging

Messaging Features OneMessage from OCENS Iridium
Privacy Person to Person

Texting with OneMessage is like any other texting with which you are familiar. You send a text to a friend..that friend and that friend only receives it.
Person to Machine

Without OneMessage, your messages are going to the GO!, not a specific person using the GO!. Whoever happens to link to the GO! first gets your text, whether or not that’s the person to whom you sent it.
Multi-User Access Allows multi-user access to the GO! for messaging. Up to five OneMessage devices can be connected to the GO! at once. Any user can create, send or check for messages at any time. Inbound messages only go to intended user. Messages cannot be created without control of the GO! GO! is inaccessible to other Iridium messaging users during this time and inbound messages, regardless to whom they were sent, all go to the person in control of the GO!
Many Threads in One Send OneMessage sends all your conversation threads in one dial You need to separately dial/send for each message you send out.
Fast Batching multiple threads into one send not only saves you time and hassle, it speeds up the actual relay because of the compression algorithms used in OneMessage. Each dial takes time to connect before the message is even sent. Connect time costs you money.
Flexible Messages available even when the GO! isn’t. OneMessage can send and receive messages over cellular connections as well. No messages can be received or sent without the GO! present.
Texting the country of Iridium Does not require international texting service on your smartphone People texting you must activate international texting on their smartphone because they are messaging to the ‘country’ of Iridium. Often $10 to $15 per month.
No International Texting Rates Eliminates high per message fees. OneMessage provides unlimited texting to the GO! for FREE. Even if international texting service is active, per message fees are still charged by many cellular carriers.
Inbound Alerts Push notifications alert OneMessage users on network connections to new messages Not available
Access to text weather data! Easily retreive SpotCast, WaveCast, FlyCast weather reports. Not available

What Our Customers Are Saying

"Love OneMail - was absolutely a crucial piece of my ability to stay connected to home while in Antarctica on my multiple expeditions this past December and January. It will be equally great to have while attempting Everest and Lhotse in Nepal during April and May of this year as well…hoping to send an email from high camp to my family and friends."


"Just to let you guys know, One Mail works great. I don't think there is anything else out there that works gmail through a sat phone. Well done."


"As an ocean rower with limited bandwidth in satellite communications (the Iridium GO), it was important for me to have reliable email communication with my shore team and others and the option to conveniently send images for my blog updates. OneMail’s ability to reliably check my existing email accounts and allow me to choose what to download gave me terrific email control."
