I agree. What’s interesting is that it’s compatible with most devices/libraries (arduino etc), compared to using a consumer level garmin device with sms/data functionality that requires a contract (to be affordable at least).

Also, even though location info is typically the main feature, I believe it’s included automatically in the msg envelope (a kind of satellite caller id), which means you can use that more expensive bandwidth for your own requirement, while still getting the lat/lon metadata.
