Satellite network and coverage claim The satellite network the device uses and the coverage the manufacturer claims for it, including any cellular or Wi-Fi fallback through a paired phone. Coverage is a manufacturer claim, not a tested result. Terrain, tree cover and buildings block satellites, and some countries restrict satellite communicators.	Iridium satellite network, which Garmin describes as 100% global. Paired with the Garmin Messenger app, messages use the phone's Wi-Fi or cellular connection and switch to satellite beyond them.Coverage is a manufacturer claim. Garmin states that some jurisdictions regulate or prohibit satellite communication devices, and battery and messaging estimates assume a clear view of the sky.

SOS coordination service How an SOS is triggered and the emergency response coordination service the manufacturer names to receive it. The named service contacts responders on your behalf. It does not guarantee rescue or a response time, and rescue costs can be the user's responsibility.	Interactive SOS from a capped button on the device, or from the Garmin Messenger app, to Garmin Response, which Garmin describes as its 24/7-staffed international coordination center; two-way messaging continues during the incident.Garmin states SOS messaging is included in all consumer plans and needs an active satellite subscription. The manual states the device sends an updated location every minute for the first 10 minutes of an SOS, then every 10 minutes. Garmin Response notifies emergency responders; this is not a guarantee of rescue or of a response time.

Tracking intervals The location-tracking send intervals the manufacturer lists and any plan or add-on that limits them. Shorter intervals use more battery and, on some plans, more credits or messages. Some tracking needs an add-on subscription.

Battery claims and their conditions Every battery-life figure the manufacturer publishes, each with the interval, mode or condition it states.
