Detecting of phone numbers and addresses is disabled in template using
<meta name="format-detection" content="telephone=no" />
<meta name="format-detection" content="address=no" />
because of a lot of false triggering, mobile browsers transform almost any sequence of numbers into clickable phone number. It's better to wrap phone numbers into <a href="tel:+1234567890">...</a> manually. But if you like, you can make a copy of mobile template and remove above lines from the template (I don't recommend to modify original templates as they will be restored when you update MobileJoomla).
PS. In Flat and Elegance templates this feature is customized in template's settings.
