I'm glad to see a lot of people are really liking the Zoleo product.
The thing to consider is if you want mapping capabilities. Zoleo is a messaging app only while InReach has robust mapping in addition to messaging.
Both services use the same satellite system so connectivity is exactly the same.
The InReach devices also allow for tracking that can be set up for remote "pinging" if desired. (Your wife can see if you really are in deer camp or at the casino)
The InReach also doubles as a GPS device and can show data such as contours and elevations once the base maps are downloaded.
