Help with sending SMS

[k_rim666]

I built an application (wap site) and i would like when the user click on SMS he will be redirected to the sms menu
I tried the same thing with TEL :
<a href="wtai://wp/mc;+4783920222" title="TEL">TEL</a> when i click on this link he will make a call to the number :+4783920222
I´m looking to do the same thing with sms but i don´t know the command in WML someone have an idea???
<a href="wtai://??????;+4783920222" title="SMS">SMS</a>

Thanks for any answer

Try <a href="sms:+0123456789>Send SMS</a>

Doesn't necessarily work on all phones (if any).

Also <a href="tel:+0123456789>Make call</a> should work for making a call.
