My main issue with 2 way and ham radio is they don't go that far. Say I'm like 50 miles away. A whole state away or something. What's the best form of emergency communication? Emergency satellite communicator I recall you have to pay some subscription fee right? Additionally, if phone lines are down, you can't expect the other person to receive that message on their phone.
The satellite one I have is a one time fee, you push a button then search and rescue come to your GPS coordinates. It’s mainly if I get stranded and it’s life and death situation.
Sadly now a days almost everything is internet based, and can be shut off remotely by governments or hackers. Wish there were more options for communication.
As for long distance, I think you would need an expensive ham radio and a huge antenna.
The garmin ones allow you to use a phone and send txt using the satellites and they have agents that help with things. That’s why they have a monthly fee. Mine only calls emergency rescue.
