I'm considering getting an InReach Messenger plus subscription, but the following question is keeping me on the fence:
Which path do messages take that are received with both my phone out of wi-fi/cell signal and the InReach device turned off (or without a view of the sky), assuming I reconnect to mobile data first?
In other words, is the service smart enough to only pull messages over satellite when needed/cancel them when received via the app first? Or would I end up paying for messages received while the device is sitting in a drawer turned off, while my phone is temporarily out of signal or battery?
Would be great if somebody from Garmin could respond here, or if somebody could test this on their device/plan (turn off both InReach and phone, receive an inbound message, turn on the phone first, InReach later: does the message count as a billed satellite message, or as a free "internet" one?).
