Answer 1

Have you tried using the System.Net.Mail functions to send mail to the email corresponding to the phone number?

e.g. [email protected]

Answer 2

Judging from your comments, I'd say leasing a SMS gateway is the easier option. I don't have any experience with USA gateway providers, but from the ones I've worked with, I can say that they are all fairly simple. Most of good ones has .Net APIs ready for you, so you essentially just call SendSMS(string phonenumber, string message) on them. If they don't have any .Net APIs they ussually have webservices ready for you, which is a 1-click integration into Visual Studio.

A simple google search came up with quite a few providers :)

1. Sending SMS is no longer free, ofcourse all ISPs dont want their customers to get spammed heavily if it would be free !!

2. If you want to send sms from your website within your .net code, then you can try clickatell.com, because anyway on webserver you cant really connect a cellphone unless you can get a chance to get into datacenter and setup your own hardware.

Answer 4

If you want to send a lot of SMS messages then a gateway and a bundle deal is by far the cheapest way to go - you generally just send an email to the gateway with the users number in the subject line. If you want something more flexible (but not as cheap) then try Email to SMS
