It's almost impossible to perform a free cell phone reverse lookup (unless you are a government agent) this is because the information is "owned" by the large cellular phone companies and charge to release the information.
I spent many hours searching the wen through those "Free" cell phone reverse lookup websites that you talk about, almost all offer a free search but after painstakingly inserting all your data every time you still have to pay for the reports ...
but they reckon the "search" is free - cheeky bunch!
Not to worry, there are reputable companies online who charge a fee for a reverse cellular phone number lookup, but they have to do this because they bought the information from the large cellular phone companies and have gone to the hassle of sorting and grouping it into a directory and then uploading it to the web.
After trial and error with other reverse cell phone lookup websites I eventually settled with Reverse Cell Phone Lookup , they're the most professional and have one of the biggest data bases, with quick and complete reports - beware some supply just a list of surnames and possible first names matches, not very helpful?!
NOTE : If you do decide to do get a paid cell phone reverse lookup then the website that you use should offer a once-off fee that allows as many searches as you like, including a membership for the year. Avoid sites that want to charge for each individual search.
Good luck with the searches and I hope that helps with your free cell phone reverse lookup question.
Cheers.
