How to send computer generated passwordlike sms messages to a cell phone through a website.?

Question

I am in the process of building a dot net nuke based website. I Would like to verify customer's cell phone number through site's automated SMS validation system by sending a computer generated password to a cell phone number which is entered by the user during the sign up process, and have them type this password at the at the verification prompt so that I'd know whoever is signing up is the person has that cell phone.
another question linked to the one above:
Is it possible to have this system run without buying a service , if not, is there a module or component that I can pay-to-own or pay-to-rent or any other way. I want this system to send this SMS password instantly or may be with a delay of no more than 30 seconds. Your answers highly appreciated

Answer 1

There are softwares for that. If you are on a linux server then do a search on that OSs catalog for something like web2sms or text2sms

personally I prefer to use email. You would have to ask what company the cell is on but I think you have to do that no matter what method you use unless you actually hook up a phone to dial the number (I would not recommend that)

Here is a link on doing it by email. You can find pages like this for other countries listing other services.
