This is a hoax. I did a report on it a while ago.
There is such thing as a no call list for land lines, but there is no such thing as a no call list for cell phones. CELL PHONE COMPANIES WILL NOT GIVE OUT YOUR NUMBER, unless you willingly give someone your number you won't get telemarketing calls on your cell phone.
This is a totally bogus scare tactic that the Internet has been doing for a while now. There are some bylaws within the system which would not allow telemarketing companies to call you anways, not to mention AT&T and other providers are guarding their customer numbers VERY closely.
Here is a brief overview of my report I did a few months back - ommited a few things for obvious security reasons.
Legal
The laws seem to be similar for cell phone as they are for land lines. The two added laws for cell phone calling are you cannot use an automatic dialer for calling cell phones or automated voice systems. The do-not-call list seems to be confusing for most people when it comes to cell phones. There have been a number of fake emails explaining people need to sign up their cell phone numbers prior to a specific date (usually June and January of every year - watch your emails!) before telemarketers get their cell phone numbers. These are fictitious emails.
If a telemarketer calls someone that is on the do-not-call list the fine is $500 dollars, and if it is proven that the company skirted the law and calling intentionally, the fine triples to $1,500. There are various details like no harassment, you have to be upfront and honest about costs associated with a product, but none actually pertain to -----
There is no special do-not-call list for cell phones. You can add your cell phone to the national do-not-call list, but that is about all a customer can do. So the only laws are for the do-not-call registry (which is the same as land lines) and absolutely no auto dialers can call a cell phone.
Costs
I couldn't find anyone that sells cell phone numbers. The only research numbers I've seen that were from cell phone numbers were either for political polls or a very small portion of research the Gallup Poll. I could not find how these companies got the numbers, but from some readings it seems like they were opt-in polls in which the respondent gave the company their cell phone for research. Also these numbers are extremely hard to get, so when searching for the difficult MDA of 18-34 males purchasing cell phone numbers is a must, otherwise companies opt for land line calling.
There are various free online sites that allow you to lookup a listed phone number for a particular person (similar to whitepages.com) or a particular address, but this is an incomplete list at best (roughly 30 million numbers of the 160 million cell phones). You also have to go one number at a time, and know either the name or address of a particular person.
Conclusion
Within the legal confines of State and Federal law, ----- can call cell phones. We do not fall under the telemarketing category, and we do not use an auto dialer for phone calls or an automated voice system. These are the two main legal matters that would concern calling cell phones. The true issue is gaining the phone numbers themselves.
There was a movement to create a large cell phone database for the purpose of using it as a national cell phone director - or known as a 411 listing. There were two issues with this database. One was that you had to choose to be included in this database. Which is fine, but most major carriers didn't promote the list. The second issue was that not all carriers offered this to their customers. So the list was incomplete and difficult to manager. Cell phone subscribers had to request to be placed on this list, and could request to be taken off at any time (both free of charge). The issue was most people weren't aware of this, and not all cell phone providers participated, so the list was abandoned.
So the major problem is getting the actual cell phone numbers. From my research I could not find one place to purchase cell phone numbers. There is not one governing body to keep these numbers, so even if we could purchase a list it would be an incomplete list comprised of just AT&T customers, or just Sprint customers. Then that brings up another issue of a stratified sample. We know that the demographics of each carrier are probably different, so if you purchased one list you would be segmenting your population.
Another issue is response rates. Statistics show that the average response rate for a land line is a little less than 50%. For cell phone numbers the response is less than 30%, sometimes lower than 10%.
