Does the Zoleo use the same network as Garmin inReach?
Yes — Zoleo uses the Iridium satellite network, providing the same pole-to-pole global coverage as Garmin inReach Mini 2. This is the key advantage over the Bivy Stick's LEO network for international or remote use.
Is Bivy Stick reliable for AT hiking?
Yes — the Bivy Stick's satellite network provides reliable coverage along the entire AT corridor in the continental US. Coverage gaps are more relevant for remote international destinations. For AT section hiking: Bivy Stick coverage is solid.
Can you use Zoleo and Bivy Stick with the same subscription?
No — they are separate platforms with separate subscriptions. Zoleo uses its own Zoleo app and subscription. Bivy Stick uses the Bivy app and Bivy/OnX subscription. You cannot transfer plans between devices.
