You can add a link on your jQuery Mobile webpage to directly call a phone number using the following format:
<a href=”tel:1234567890″ data-role=”button” rel=”external”>Phone: (123) 456-7890</a>
Be sure to put in rel=”external”.
When you click on the link, your phone app on your smartphone will be brought up with the number 1234567890 set. All you have to do is hit “Call” to make the phone call. Try it out on your iPhone or Android phone!
