Motorola Defy Satellite Link Review

The Motorola Defy Satellite Link is a revolutionary device that allows users to send messages back and forth, as well as send SOS signals via satellite. This functionality proves crucial in places where cellular Wi-Fi connection is non-existent, such as the backcountry. The Defy is comparable to an Garmin inReach, but far more affordable.

In this Guide:
  • How the Defy Performed
  • Differences With inReach & ZOLEO
  • Is the Defy Right for You?

Design and Usability

Weighing under 70 grams, the Motorola Defy Satellite Link is smaller than a deck of cards. Its rugged design is perfect for outdoor adventures. The buttons have a tactile click feel, and there is haptic feedback confirming successful button presses. The device meets military specifications and is rated IP68, meaning it's resistant to dust, dirt, and sand, and is water-resistant. However, it lacks a carabiner and merely features a small clip on top, so a carabiner needs to be added for secure attachment to a backpack.

One potential design flaw is the uncovered SOS button, which may accidentally be pressed if carried inside a pack. Perhaps a protective cover will be introduced in future versions to mitigate this risk.

The device charges using a USB-C port and includes a USB-C to USB-A cable. Despite some initial hiccups during the setup process, overall, the device hardware proved reliable and robust.

Features and Messaging

The Motorola Defy Satellite Link is a messaging device. Users must download the Bullit app and set up an account, which requires an initial data connection. The device uses your phone number as your account ID. Unlike the ZOLEO, the device does not have a dedicated phone number or email.

The Bullit app pairs with your phone via Bluetooth and is compatible with both iPhones and Android 10+ devices. The app also allows users to set up an SOS emergency contact and provide information about any medical conditions they might have. Messaging works via the Bullit app, which automatically switches to Wi-Fi or cellular if these connections are available.

Satellite and Battery Performance

The device's satellite system provides an almost instantaneous messaging service, which is impressive. However, the device occasionally lost the satellite connection, particularly when in a northward facing position, likely due to the satellites' southern horizon positioning.

Battery life for the Motorola Defy Satellite Link is listed as up to four days, although this varies based on usage frequency. In my testing, the battery lasted between 65 to 70 hours with the device continuously on and under regular use. Charging is made convenient by the USB-C port, allowing for easy integration with other charging systems.

Emergency Services

One of the key features of the Motorola Defy Satellite Link is its SOS capability. In an emergency, users can press the SOS button, sending a signal to emergency services via FocusPoint International, a well-established organization providing global emergency response services. While the company doesn't have a blog with rescue stories, news stories show hikers being rescued using their service.

Update After a Few Weeks


For a basic messaging and SOS service in the backcountry, the Motorola Defy Satellite Link offers impressive functionality at a reasonable price. However, for those requiring worldwide coverage, navigation functions, location sharing, and weather reports, devices like the Garmin inReach or ZOLEO may be a better fit. Overall, the device's compact form factor, coupled with its robust design and intuitive functionality, makes it a worthy consideration for outdoor enthusiasts. As technology advances, we can expect even more comprehensive and user-friendly devices to emerge in the future.
