I am considering getting a Garmin InReach device (a device allowing two-way satellite communication via text messages) and I am trying to decipher the hidden costs of the subscription that comes along.
If I understand correctly how it works, the communication is possible by sending a message to a regular phone number, to an email, to another InReach device. In the case where I send an email to some friends or family members, I assume they can reply for free.
The subscription page lists the pricing for sending a different kinds of messages and receiving the weather forecast, but it never mentions a price for receiving messages, nor does the help section of the website.
When I use an InReach device, is there any cost when I receive a message, either for me or for the sender?
