Trackers for Cali and her two bikes. No subscription if poss?

[Birty]

Any suggestions.. 3 trackers with no subscription.. Is this possible?? Love my cali but love my bikes more! Really don't want an annual bill.. retiring soon you know!! Have a ghost 2 immobiliser fitted currently but feel a tracker would also help...

All trackers will need some kind of Sim card or subs, I use a TK104 and a pay as you go sim. I probably spend only £10 a quarter for the Sim card. I doubt you can do it much cheaper than that. Subscription systems will certainly remove any need to manage sim cards which may be worth the extra cost.

They do use about 0.1amps per hour so for bikes they may need some kind of charger to keep the battery topped up?
