Sending a SMS to a cell phone

[a_curious_one]

Hi there!

I'm new in .NET development. I'm just curious about something.

I want to create an application, so i can send a SMS to a cell phone. A form
with two textboxes and a button (textboxes for the phone number and Message
and a "SEND" button)

Is it possible for any cell phone ?

Is it possible without a contract with a company ?

Do i have to do anything special, or i just can write some code and launch
the application (ofcourse, an internet connection is available ) ?

What should i do ?

I ask you this because i don't know any sites where i can send as many SMS
as i want. I want to do this.

Thankyou very much!

First of all, to send a SMS you need to have an account with a SMS gateway
(that is if you are not sending the SMS through your mobile phone). So you
do need access to a SMS gateway.

Or you can use a GSM Modem attached to your computer and send an SMS using
the AT commands supported in the modem.
