I am wondering how can I open the send SMS application by using a web control of a HTML5 page on Android and iPhone. I want to use the device native SMS sending app, with a prepopulated value from the web.

                    It looks like Android is limited to just a number - it will not parse the body into the created SMS message – Mampersat May 03 '12 at 20:18

                    On iPhone it only works if you format the number with international dialling code (eg. +43123333) and not with 0 in front (eg. 0123333). SMS text is not allowed - even number is then ignored. – besimple Jun 05 '14 at 11:07

            Further to other answers I can confirm that smsto:555:bodytext does not work on an iPhone running iOS5.
What does work (and I've tested it) on Android is the format:
sms:444?body=hello
Example:
<a href="sms:444?body=hello">Tap to say hello!</a>
On iPhone the ?body=hello will prevent it working at all, and you should use just sms:555 instead.
sms:555
Example
<a href="sms:444">Tap to text us!</a>

                    Ben, I do not understand how can you claim that body attribute works in Android, it does not atleast in stock Android Browser and a bug12142 (http://code.google.com/p/android/issues/detail?id=12142 ) exists for this which is still not resolved. What works is a URI with only the number, body attribute does not work – Raks May 14 '12 at 11:57

                    Hiya. The body tag definitely worked on the devices I tested with at the time, I should have written down which they were. It's possible that 'stock' Android doesn't support this I suppose. – Ben Clayton Apr 15 '13 at 13:43

        I have tested the below and it works:
Using HTML Anchor tag:
<a href="sms:111?body=SUBSCRIBE">Subscribe</a>
Using JavaScript:
window.open('sms:111?body=SUBSCRIBE', '_self');

        With Android 3.0 SDK Google has started exposing API in HTML5 for device access. An example is listed here. It may not be enough for what you seek to do.
I dont know enough about iphone to advise either way.
