Performing a reverse lookup on a cell phone number is often significantly more difficult than performing one on a landline number, but it can be done. While using reverse-lookup search engines for landline numbers is free, performing them for cell numbers often costs a small fee.
A free alternative to using reverse cellphone lookup services is to try searching for the number in a standard Internet search engine or on social networks. If the phone number is listed on an online job application or blog, it may show up in a engine search. Likewise, social networks like Facebook allow users the option of listing a phone number with their profile, so it may be possible to find the owner of the cell number that way.
