Satellite tracking using Garmin InReach
We bought a Garmin InReach and love it!
I use the Garmin InReach (https://amzn.to/2vld49N) to track our position and let us exchange unlimited text messages ($65/month) with family from the middle of the ocean... but that doesn't tell them the time difference or when we are next in port and might have WiFi to Skype with them.
