How can I locate my lost phone using gps?

[SalinaGomez]

I lost my phone a few days ago. My phone company told me that they can't track it because I didn't pay for the tracking when I first bought the phone, but I have used it for gps, directions, etc, so obviously it is able to be satellite located. Is there any way that I can use a site online or a different method to locate it myself? I've seen sites online that say they can, but I don't know if they are safe to use.

Also, whenever we have tried to call it it goes straight to voicemail, so it is off. Will this make it impossible to find?

I don't think it was stolen, because the customer service people have told us the last time it was used, and I know it was me who made the call. If someone stole it they'd be using it, right?
