title: How can I make a website button open up an SMS compose to a phone number?
body: <p>I've found solutions that make it so that when you click a button on a website, it links to a phone number and the users phone will open up the dialer with that number pre-filled like so.</p>
  
  <p>What I want to do instead is open up the users sms application in "compose message" mode to that specific number. Is there any way to do this? I've tried the following approach, but it doesn't work on Android: </p>
  
  <pre><code>sms://1-516-400-6217
  </code></pre>
