Vibrate plugin provides you functionality to vibrate your mobile user’s mobile with custom popup. Once user access your site a popup box with customized text will appear on home page and mobile will vibrate. However, this doesn’t mean that your device can vibrate. There are a few requirements you need to meet. You need the hardware for it. The page needs to be visible. Browser-specific implementation prevents the vibration.
