Here's a heads up for all of us -
Several issues have surfaced in the last couple of months in regards to messages sent from the InReach device actually reaching all listed contacts. My buddy uses his InReach device to keep his wife and daughter aware of his status and location when doing trail work - riding and packing with mules, running chain saws, falling trees, clearing trails. "I want them to know I'm okay and not laying in the dirt somewhere doing the funky chicken." His wife and daughter suddenly stopped receiving InReach text messages to their phones. He still received the messages to his phone - same plan, same cell carrier. Several phone calls to Garmin tech and weeks of sorting it out and sending test messages revealed problems with the phone numbers Garmin/InReach used to send the text messages.
Two months ago a friend of ours noticed she stopped receiving our InReach text messages sent to her cell phone. It always worked before. This issue has still not been resolved.
A couple of weeks ago my buddy and I noticed that our contacts with a comcast.net email address stopped receiving InReach messages. These issues will get bounced back and forth - "It must be comcast's problem." Turned out in was. For some reason comcast started to block all emails from InReach. That issue has been fixed.
Moral to the story. Get a hold of all your contacts and set up a test sending a preset message. Ask them to confirm your message was received. If not, contact InReach/Garmin tech support and help them find and correct the issue. These messages need to get to intended contacts.
