Send sms with ICQ API

hi all,
I want to know if someone can tell how to send sms with the API of ICQ...
I know that ther is a way to do it, but I dont know how...
i'll be happy if someone can help me with this issue...
any tutorial or guide woukd be welcome...

Why use ICQ specifically ?
Lots of sms gateways out there.
Here's one I use: http://misronim.appspot.com
You use HTTP POST to send your message.

ohhh, you right,
I dont need specifically ICQ, the point is that I need to send sms.
I'll check it!
Thank you

And one more thing...
I need to send it programitically,
and I need to use it for free!!

Sending for free would be nice and there are actually some ways to accomplish this.
For instance, many operators have an E-mail adress that you can send a message to and it will be converted to an SMS message.
Other services work on the basis that as long as you recieve a reply (incoming) message from your recipient, your outgoing messages are free.
The problem is that these services are usually limited and only partially reliable.
In my experience, if you really need SMS messaging for your app that can be monitored and be relied on to work every time you need it - you should invest in a paid service. Many services (such as the one I mentioned) have an application interface so you can achieve sending the messages programmatically quite easily.
