ZOLEO Overview

ZOLEO sends and receives messages via the Iridium global satellite network when you’re outside of cellular coverage. The free app works via cellular or Wi-Fi when its available—satellite when it isn't. You’ll never miss a message even if your ZOLEO device's power isn’t on.

ZODEO works with its own app on iPhone or Android.

ZOLEO coverage is unique because it uses satellite, cellular and Wi-Fi for a truly seamless, global messaging service. ZOLEO takes advantage of cellular and Wi-Fi when it is available, and transmits over the Iridium satellite network when it isn’t! You experience a messaging service that simply isn’t available using other satellite communicators.
