Can a iphone somehow still be tracked if the SIM card is taken out?

If a thief took out the SIM Card and restored the iPhone to factory settings, can the phone somehow still be tracked by the carrier or by the police? And if they put in a new SIM card will that make it tracksble? :/

No, that is why you report it stolen, so that the phone gets blacklisted by the carrier, that way even if the person with the phone resets it and is able to use it, they will not be able to activate it on any carrier, in North America, Europe and most of Asia,

With an app like Prey from the Prey Project, you could be alerted when a new SIM is put into the phone, and it can even tell you what the new SIM's number is, to help the police get the information about the account holder, like front and back cam pictures of the person using the phone (depending on which OS your phone uses) and where they might be using it, IP and GPS info about where the phone is, and direct the POLICE to where you phone is. But once the phone gets reset, even Prey can't help you track the phone. But it can while it have GPS and Internet connections allow you to lock the phone and have it ping it's location and even alarm which the person with the phone can't turn off. Yes. The phone has a GPS in it.

Yes. The phone has a GPS in it.
