With LoJack dead in the US, what is a classic car GPS tracking alternative?

Lojacks support was / is not that great I tried to test the early warning system several times and it never worked so I finally bitched them out and they replaced my sending unit which requires taking the interior apart that I had just finished only to find out from the tech that in order for the early warning to work I had to drive the car with the key fob and then it had to move without the key fob for at least 20 minutes which I tested after he told me and it still never gave me any notification
so, I have a new unit but still don't know if it would ever work and how long do I want their battery inside the body panel of my car wtf
