Getting contacted from various device types needs a solution suited for both – One for mobile, and one for desktop (as mobile devices can usually use the phone functions, and desktop would use a chat client)

For mobile, we usually use the Call now plugin which lets visitors on their mobile devices ring a mobile directly. The other is for desktop and called the Skype live messenger. These only appears on devices with a wider viewport. The devices don’t behave this way normally, so you’ll have to use the @Media command in CSS to parse the required button to appear when you need it per device.

@media only screen 
    and (min-device-width : 320px) 
    and (max-device-width : 480px)
		and (orientation:portrait)

The code above should give you an idea of what’s happening as the site loads for different visitors.

Personal experience

Use cases

Use them for a great way to let customers contact you quickly.
