You have a cell phone number and look for the name and address. A mobile phone reverse reverse look-up directory will give you access to these data.
If you have a phone number but don't know to whom this number belongs to or what address is related to you will need a Reverse Phone Lookup to find the required details.
You'll find many places on the Internet where you will find residential, business phone and toll-free numbers lookups for free.
But is a reverse cell phone lookup on the Internet also free?
Cell phone numbers are only held by telecommunications companies and carriers and they don't give them away for free. It's similar with unlisted numbers and fax numbers.
