Detect if Internet browsing device is capable of sending an SMS?

Is there a way to detect if the device being used to browse a web page is capable of sending an SMS? Or is there a way to make a guess that is correct say 90% of the time?

Example: Right now I am showing a "Send as text message" button here

at the bottom of this page. I show it for all users but would obviously like to limit it to devices capable of sending an SMS.
