Been using a Garmin inreach for the past couple of years. Even worked when i went to Patagonia. You can find them at Costco the cheapest for $250 or under $200 sometimes on sale. They have redesigned the sos button so it can't be activated accidentally, its no longer a slider, it now has a cover then has to be removed then pushed and it will ask you to confirm. The subscription plan is nice and can be activated for a month then shut off then reactivated when you want. you can text message and along with that msg it will send a link to pull up a map with coordinates from when/where that msg was sent.
I read a few months back that some snowmobiler broke his leg and turned on his spot and it was blinking but never actually sent a signal. A friend of his ended up rescuing him and spot wouldn't tell him why the device failed to send the signal. With the garmin you get the ability to txt to a phone number, email etc. So if i was injured, if capable, i could text a parent and then also hit the sos, better to have two people know you're hurt than none at all.
The problem with the in reach mini is that it pairs to your cell so if your cell dies you can no longer msg with it, if you have the in reach se you can hook up the bluetooth and use your phone to type, but if you phone dies you can still use the device to slowly type out a msg.
