How to make phone calls and send SMS messages from a simple web page
Not many people know about this cool fact. A very simple trick allows you to make telephone calls and send SMS messages from web pages when you view them from a smartphone.
All you need is some basic knowledge about HTML. If you have that basic knowledge you know what a hyperlink is. In raw HTML it looks something like this:
This is a <a href="http://www.example.com">link</a> in a sentence.
You probably also know how to open your user's email client using a very similar syntax:
Send us an <a href="mailto:email@example.com">email</a> to get a quote
The only difference is the prefix "mailto:" before the actual email address. That is called a <em>URI scheme</em> and that specific URI scheme makes the browser open the default email program once the users clicks it.
There are many URI schemes, and two of them are "tel:" and "sms:".
How to make a phone call from your web page

Send us an <a href="sms:+123456789">SMS</a> with your request
