How can you look up a cell phone number?

Try to stay away from all those Net Detective scams, offering unlimited number lookups for $20 or so, those just provide an easy to use front end application to public databases like yellowpages or anywho and won't assist with looking up any unlisted or cellular phone number information.

Also, if you're going to pay for real results, make sure you go with a company that gives you a money back guarantee and fully outlines what the search will provide. Alot of places will just tell you the carrier of a cellular phone number and charge you for it! The carrier for any number can be located free of charge at websites like fonefinder.
