I do hope you're kidding.
There have been ham handhelds since the late 1970's.
Before that they were "luggables."

In some cases such a radio might be a best solution. You might want to investigate actual repeater coverage of your area though. No coverage = no utility.
You'd be investigating how to access those repeaters. The radio isn't like a CB or FRS radio where you just turn it on and go.

I recommend you get then get a license to use it. If you use it without a license (totally legal in an emergency) you would have to spend a fair amount of time convincing the folks you'd contact that you do indeed have a legitimate emergency and aren't spoofing.
Getting a license isn't very difficult (it's easier than it has ever been) and you might learn something useful in the technical realm.
