Is there a site anywhere that will help you find cell phone numbers without charging a fee?

I am having some problems with my husband and his cell phone friend. How can I find out numbers and who they belong to? I know somebody out there has had this same problem and can help me. I don't have a credit card and can't look them up that way. There must be a way to help good people find out about the bad ones that are doing them wrong.Is there a site anywhere that will help you find cell phone numbers without charging a fee?
i can 100% tell you that you cannot find it for a cell without paying. I have to search these #'s for work. I promise you that you cannot. AS far the answer above from another user. Yellowpages.com cannot give you this information either. You can do a reverse # in whitepages.com but only for registered landlines. It will tell you if it is a cell and the cell company but the not the owners name. If the landlind is a registered # you can get their names and addresses but if they are not registered, it will only tell you landline and phone company name.Is there a site anywhere that will help you find cell phone numbers without charging a fee?
do you have the number and just need the name? What about yellowpages.com and just do reverse number, it usually tells you if its a land line or cell phone and the name of the person it belongs to.
