How do you find a cell phone number owner? Can you actually do it? Yes you can.
There are basically two ways to do this.

1. Use a Private Detective service - Too expensive (~$200) and too slow (up to two weeks)
2. Use an online Reverse Phone Lookup service - price ranges from $0.
   99 to $99 and takes only two minutes

The private detectives are indeed the old fashioned day, however a lot of people still do it just because that's what they're used to.
However it is not the most advisable thing given that they're too expensive and too slow.
Undoubtedly, the best way to do this is by sticking to a Reverse Cell Phone Search tool that can be found online.
They too were really expensive initially, I remember paying $69 to find out a telephone number a couple of years ago.
But with the advancements in telecommunications technology, like everything else, reverse phone lookup is also becoming extremely cheap.
The Cheapest Service The cheapest service I've seen by far costs only 99 cents.
It actually costs $5 ($4.
95 I think), but they offer you an optional trial for an identity protection package and if you take that $5 comes down to 99 cents.
If you call and cancel the trial within seven days you pay nothing more than 99 cents.
However it's completely your decision whether to opt for the identity protection trial or not to and if you do so whether to keep it or not.
Other services start from $15 - $99 ($200 if you're in the UK).
Compared to these services, 99 cents (or even 5 bucks) is nothing.
The Scammy Websites There are also other 'services' that offer to do a Reverse Telephone Number Search in exchange for your own cell  number.
I don't know about you, but I certainly try to keep away from these as I'm not willing to sacrifice my personal information in exchange for finding a phone owner.
