Your smartphone is powerful, but the moment you lose cell signal, it becomes an expensive paperweight. The Bivystick changes that equation. This small, lightweight satellite communicator pairs with your existing phone via Bluetooth, giving you two-way messaging, GPS tracking, and SOS capability anywhere on the planet using the Iridium satellite network. No cell towers required. You type on the screen you already know—your phone—and the Bivystick handles transmission through space. It's ideal for hikers, backcountry skiers, overlanders, and anyone who ventures beyond cell coverage but doesn't want to carry a dedicated satellite phone. The SOS button connects you to GEOS emergency response, and your contacts can track your location in real time through a web portal.

The Bivystick: Turn Your Smartphone Into a Satellite Messenger

Expert Tip: Getting the Most Out of Your Bivystick
The Bivystick performs best when used strategically. Satellite messaging is slower than standard SMS, so expect approximately 30–60 seconds for a message to transmit. To save time in the field, pre-write common messages—such as safety check-ins or arrival confirmations—before leaving cellular service so you can send them quickly when needed.
Clear sky visibility is essential for reliable satellite connection. In canyons, dense forests, or obstructed terrain, move to a clearing or ridgeline to improve transmission. For optimal signal performance, clip the Bivystick to the outside of your pack with the logo facing upward, as the antenna is positioned on that side.
FAQs:
- Does the Bivystick require a subscription? Yes. The Bivystick operates on the Iridium satellite network and requires an active service plan for messaging and tracking. Plans range from basic check-in packages to unlimited messaging options.
- What phones are compatible with the Bivystick? The Bivystick connects via Bluetooth to both iOS and Android devices. Simply download the Bivy app to send messages, view maps, and manage tracking features. Your phone does not need cellular service—only Bluetooth connectivity to the device.
