Unfortunately sms: is not an official protocol. Some companies like Sony Ericsson decided to add it and support it.
Probably some Samsung will support sms: some others will not as they embed different browsers in different models.

I don't think there is a real alternative that will work on all browsers, unfortunately.

But it does work on S60 and Motorola (which??). That's interesting.

some phones seem to require smsto: instead. It's all in WURFL now.

With the update of TA-DA we have now added two new properties, uriSchemeSms and uriSchemeSmsTo.

Information is now coming from TA-DA only, so you are more than welcome to test it directly on your device. Information coming from our sources, including WURFL, will start popping up quickly.

It's a shame that it's hit or miss like that ;\

It certainly is :(

I've tested using 2 Series 60 Nokia devices and neither of them support smsto. We can only hope that enough people run through TADA so we can build up an accurate picture of the devices that support sms/smsto/both!

We recently added the property to DeviceAtlas, if you did not notice. Sources are currently WURFL and our own testing via TA-DA.

Get working with it, then! :)

Whoa thats awesome news! I think I should get working on it too.!

SMS: works well on all decent Nokia S60, SE.
Also it works with most newsest LG and Samsungs, like S8000 Jet, S5230, KP500 and so on
It works with Motorola based on MotoMagx(V8) and iPhone, but embedding SMS text is not supported

Nokia S40 works well with mailto: instead of sms: :)

p.s. Note, that when user is using Opera Mini things change a lot

Great thread. I'm enjoying going through the tests on the Droid right now. Good stuff, now I just have to figure out how to resume them.

Hi all....thanks for all the information in this thread. I am also working with the wtai protocol but in a slightly different way. I am creating html files including wtai links for sending a sms with prefilled body and send them to phones via bluetooth.

I know about the difference with "sms" and "smsto". On SonyEricsson, both is working but the issue is that the SE phone includes an unknown character at the very beginning of the body but deletes the last character. The first character seems to be a linebreak since the phone shows that the message is 2 or even 3 sms long but it's definitively less than 160 chars. When i delete the first unknown character, the phone says, the message is only 1 sms.

Afaik this happens only on phone like the SE K800, W850 (at least i have them both here for testing). Phones like the K750 or W800 don't show this issue.

Here is the code i am using

<a href="smsto:88044?body=KEYWORD%20This%20is%20the%20body">Send us your answer</a>

Did anyone encounter something similar?

PS: to get rid of the issue of deleting the last character, i simply put a white space using %20 at the end of the body.
