how can I find out how to use it?

Yes your Sanyo has a cellphone tracker but that feature can only be used by law enforcement agencies, and they would need to contact your cellphone provider in order to have it activated. Hope this answers your questions.

That's odd! Sprint advertises their tracker service on their website! Great for parents who want to keep tabs on their kids or businesses that want to keep track of employees. It's not free, but it is pretty reasonable. And WAY COOL!You can't use the service to track someone else's phone, but it's perfectly legal to track a phone that you personally own.

here is the thing you need one of the newer phones to be able to do this. parent phones and child phones in order for it to work properly
