The RockFLEET Worldwide Tracking Device is a true global tracking device designed for long-term use on maritime boats and land vehicles. It contains an optional GSM unit that allows it to use terrestrial mobile phone networks when available, switching to the global Iridium satellite network when GSM is unavailable. Also, because it's made by Rock 7, you can expect it to work exactly how you want it to.
A coupled Bluetooth device (such as a smartphone) and the Messenger app can also be used to send short messages (such as SMS, social network updates, and short emails). This enables for full two-way communication no matter where you are, even if you are out of range of a mobile network.
GSM and Iridium work together to provide a cost-effective and genuinely global method of tracking and interacting with your assets, no matter where they are.

How does it work? RockFLEET uses the Iridium Satellite network. Specifically, it uses an Iridium service called 'Short Burst Data' (SBD). There's some official info here. At the heart of RockFLEET is an Iridium 9602 modem.
Got up and going about six months ago, thanks to Apollo for all their help. I mainly use it for the tracking features but the fact that I can send and receive messages has been very helpful.
