I am concerned being charged for text messages while on my phone data. Per Garmin: Messages sent using a wireless connection or cellular data on your phone do not incur data charges or additional charges on your inReach subscription. Messages received may incur charges if message delivery is attempted over both the Iridium satellite network and the internet. So I risk being charged for an incoming text, while on my data, if they attempted it through the satellite network. Something doesn't sound right about that. So I am in cell service, make 100 texts that I am not charged for, but I receive 100 text replying to my texts and I get charged because several of them were also sent to the network. What am I missing?
