Phil, I use the Freedom Recreation Plan at $35 per month. I think there's some other fees on top of that. They have three different levels of personal plans and those are priced at either a cheaper annual cost, or a monthly cost. A nice part of the inReach billing, is you can shut your subscription off for the months you don't need it. So I shut mine off last October and haven't turned it on yet. Here's a link to their subscription plans.

I don't bother with the text messaging with the inReach. Since I usually stay in a motel at night or at ToddC's place, I can call or text from the motel to my wife each night. What I have it for, is the tracking. With the exception of I-90 that goes over Snoqualmie Pass, none of the other highways in Washington state have cell coverage all the way over to the border. Even some of the side roads here in the state that are local in the Seattle area, don't have cell coverage. So I turn my inReach on when I leave in the morning on a trip and turn it off when I get to where I'm staying for the night. Battery life like that is about 3+ days. It gives my wife peace of mind, and the cost is well worth it for that.
Another benefit I find that I've only used occasionally is the free Earthmate app subscription. I can download detailed topographical maps to my smartphone and use the app in conjunction with the inReach to see where I'm at and where a trail goes, like for hiking or fishing. It'd work too if you were doing off-road riding.
Garmin offers several models of the inReach. I got the DeLorme inReach SE several years ago. I would not opt for the Explorer version unless the cost was minimal. Everything you want to do for mapping, route planning, etc. can be done on the smartphone. The Explorer screen is too small to be useful except for making some menu selections. Otherwise, the Explorer is no different than the SE. Garmin also has a "mini" version. If it comes with the Earthmate app, that would be an interesting alternative.
Some people make a big deal out of carrying it on their body while riding so that if they crash and can't get to the bike, they can call for help with the unit on themselves. I'm not too worried about that and simply hook it on my tank bag. If I crash and my wife wants to find my body, she can just look at the map and see where I was last at. But the choice is yours for where to put it.
Regarding SPOT vs inReach...I looked at the SPOT several years ago. It was the only one I'd heard of at the time. When I started digging into user reviews on the SPOT, there were quite a few of them that had some negative comments. Things may have changed, but there were three major factors that swung me towards the inReach.
- Two-way communication. The SPOT was only one-way. The inReach was two-way. In other words, you would send a text to your Sweetie...or an SOS...and not have any feedback that it actually was transmitted.
- Failure to send. The SPOT owners said (if I remember right) there was about a 35% or greater chance the message you sent, was never actually sent. That's inconvenient if you're texting your Sweetie...and disastrous if you're sending an SOS.
- Billing. The SPOT plans at the time were annual only. While the monthly cost was less, the annual cost came out more than if you used the inReach and suspended your plan when you didn't need it.
I've owned mine since 2016, I think and have no issues with it at all. If it died...I'd buy another. Highly recommend it.
