That satellite device is pretty nifty. I can see that it would be useful if you are out trekking in the wild without network access. However, it is another (costly) electronic device to carry and another monthly fee to pay.
A simple solution may be to use an app like Zoner on your phone. One of the features is to find the location of your phone. Your friend or relative with the code sends a coded text to your phone. The app turns on your phone gps, takes a gps reading and then the app texts the gps location back to your friend or relative. It is a simple solution but requires you be in a civilized area witha network to receive and send texts. Usually no additional travel plan is required (incoming international texts should be free and outgoing texts will cost you about 60 cents). Of course you and your phone can be separated, but the same could be said for that sat device. This solution may give you and your family some measure of security that you may be located if lost.

One of the most sought after features is Sleep Tracking: in the fitness tracking section, but sleep tracking is kind of its own topic, since not everyone works out and keep track of sleep mode. The best part of a smartwatch for travel is that you can use some high level tech to fight against jet lag.
Track your sleep (and see when you’re waking up during the night), set alerts for when to power down, and use one of my favorite smartwatch features—vibrate to wake. Ditch the outdated buzz of an alarm clock and wake up with a gentle nudge from your smartwatch to take on the day.
