No FAA issues and yes you need to register them. The Coast Guard will first call your contact(s) and see if it is a false signal and if not then they're coming. You can have many contacts, I had 6, so they'll definitely find someone.
You can use them before registering but they won't know who to call to see if it is a legitimate emergency, but I'll bet they'll come regardless.
Also, you have to re-register every so many years, like maybe every 3-5 years, I forget.
I do a lot of solo distance traveling and cell phones are only good in urban areas or along the Interstates which I try to avoid both. When you're in the mountains or desert, IMHO you need this peace of mind. The only requirement is that the EPIRB 'see' the sky! ie no very dense tree cover, etc.
