Xcode simulator, link is invalid sending SMS in HTML webpage, why?

I'm not familiar with xCode, I'm using the iPhone 6 simulator to view a simple site in Safari. The webpage has a link which should open up the simulators SMS messenger:

   <a href="sms:12345678?body=Hello my friend">Send SMS</a> 

However, in the simulator when I click on this link I get following alert:

"Safari cannot open this page because the address appears to be invalid"

My question is, do I get this message because I'm missing some services of files for the simulator, or I'm I doing something else wrong?
