i am not associated with any of these companies, just doing my own research as the deadline is getting closer...
while bouncie is on our radar, it seems that vyncs is overlooked as a considerable alternative.
two things about these alternatives:
1. bouncie currently has no way of tracking a vehicle when the ignition is off. this is a dealbreaker. however, support told me that in a few months they should have a tow feature, which is a software update and not a hardware one which allows pinging a parked vehicle. so the eta is pending and the details still unknown how this will function.
2. vsyncs has no monthly fees, but there is a purchase fee + an activation fee and later an annual fee. they have a price comparison chart (which includes bouncie) here, claiming to be the cheapest:

i don't put the numbers since they could all change.

automatic - make sure to check our their privacy pages if you haven't and if a california resident, opt out of their selling info to third parties -

i'm still looking into this but bouncie had made the news a few years back about possibly selling customer data to insurance companies among other third parties. they are also linked with another company at the same address in texas. do you own research.
vynscs, still looking into this.
all other alternatives seem to have monthly fees that add up substantially or more focused on vehicle hotspots that become out of this scope, and focus more into the realm of cellular data rates and extra charges with less focus on vehicle tracking and vehicle data.
