There are a lot of scams with cell phone number search. There are private companies that do false advertising and if and when you pay will not get your money back if you are not satisfied.  Out of 24 sites looked into, only 3 were found trustworthy and these 3 only charge a small fee.  Studies have shown the best way to do a search is through reverse cell phone search.  I needed to find a relative that I hadn’t been in touch with for a long time and I needed to get hold of her. I did get on a reputable site and was able to contact her.
