Sometimes, you need to be in communication no matter where you are in the world. That's where the Iridium satellite constellation comes into play. With the right device, you need never be "out of the office."
Satellite phones and plans are expensive, but if you're OK with limiting your communications to text, then the ZOLEO Satellite Communicator is an extremely affordable when traveling beyond cellular coverage zones.
What makes the ZOLEO different is that you get a dedicated SMS number that works whether you're in or out of cellular coverage. You also get a unique email address that follows you around the globe.
Unlike other networks, you get long messages with the ZOLEO, up to 950 characters.
The ZOLEO is controlled using an app that you install on your smartphone or tablet, which controls two-way messaging, SOS alerting, check in, weather forecasts, and location sharing. The app will intelligently switch between the Iridium network and cellular/Wi-Fi when available to send and receive messages.
