The Garmin Edge Explore 1000 has "incident reporting" (probably, the only device that does that).

These devices provide tracking without needing a cell phone but they are not cycle computers.

You have to press a "rescue me" button or fail to "report in" to get help.

The Edge 1000 has a "crash detection" feature but it also requires a smart phone.

An InReach or SPOT device can leave a bread crumb trail and it goes through a system that's used for search and rescue. These devices are fairly expensive and carry a monthly fee because they go through a for-profit satellite network. These have an SOS button, so if nobody is watching the trail at home, you can call for help as long as your hands aren't broken and you can reach the device.
