A screenless Iridium communicator that turns a phone running the Bivy app into a satellite messenger, with SOS and check-in buttons on the device, a dedicated number and credit-based plans.

Satellite network and coverage claim
Iridium satellite network; ACR describes 100% global coverage, and the user guide states all Bivy plans use the Iridium network.
SOS coordination service
Dedicated SOS button under a red flap, or SOS in the Bivy app, with 24/7 SOS monitoring by Global Rescue and two-way texting with Global Rescue through the app.
Plan structure
Active Bivy base data plan required, chosen in the Bivy app at activation: Basic, Plus or Unlimited, monthly or annual (one-year contract). Credit-based: messages, weather and tracking use credits; check-ins are free. An initial commitment period and a one-time activation fee apply.

Before you choose.

Which plan will the device need?

Every device here requires an active subscription for messaging and SOS. Plans differ in minimum term, monthly or annual billing, message allowances and whether service can be paused, and activation fees apply.

Does the network cover where you go?

Iridium devices carry global coverage claims, while SPOT's Globalstar map separates SOS and two-way message coverage by region. Every coverage claim assumes a clear view of the sky.

Who receives an SOS, and what happens next?

Each maker routes SOS alerts to a named coordination service that contacts responders. That is not a guarantee of rescue, and rescue costs can fall to the user.

Will you type on the device or on your phone?

Devices with a screen and keyboard can message without a phone. Screenless devices rely on an app for anything beyond check-in and SOS.
