+1 on the inReach. I have the old Delorme model, too, and it has served me well.AgEng06 said:
Look into the Garmin (formerly DeLorme) inReach. It's a sat/gps unit that allows text messaging. It also pairs with your phone and the Maps app. They have service plans where you only pay when you use it (in monthly blocks).

It does a great job of giving peace of mind to spouses/friends/family when you are out all day. It sends tracking points every so often and anyone with the private link can follow along and see where your route.
Being able to send and receive text messages also helps with scheduling pickups or letting someone know you are running early/late.
I never used their mapping functionality in their app as I prefer the GaiaGPS app.
