Telephone Link Protocol
We've always been able to create links with protocols other than the usual HTTP, like mailto, skype, irc ,and more; they're an excellent convenience to visitors. With mobile phone browsers having become infinitely more usable, we can now extend that convenience to phone numbers:
tel protocol is used for phone numbers:
<a href="tel:18008675309">Call Jenny!</a>
If you'd like to create a link for SMS text messaging, that's easy enough too:
<a href="sms:18008675309">Text Jenny!</a>
sms protocol is used for text.
