This is a WordPress plugin that adds a Call Now button (click-to-call) to the bottom of the screen which is only visible for your mobile visitors. Because your mobile visitors are already holding their phone it will allow them to call you with one simple touch of the button.

The settings are very easy: enable and enter your phone number. That’s it.

If you want to add some text to your button, that’s possible. Entering text is fully optional – leaving it empty will show a nice phone icon to your visitors.

You want even more control? Open up the Advanced Settings and change the default behavior.
