How it connects
Alpha 200i · non-stim · v10 · 2026-03. For satellite messaging, open inReach > Messages, select an existing conversation and message, then its information tab; record status and time without sending or deleting. GPS reception and VHF collar/contact communication are separate from Iridium messaging. Garmin Messenger can use phone Wi-Fi or cellular data, so an app conversation is not proof of satellite delivery. In the already paired Garmin Messenger or Garmin Explore app, read Device connection status and whether existing data has synced. Confirm the existing inReach subscription with the provider; do not start a new plan. Check safe open-sky placement and keep device IDs, contacts and location private. Do not force Check Mailbox, send test messages or tracks, reset, flash or activate SOS for diagnosis.
