CallPhone039r is a WordPress plugin designed to enhance customer interaction for mobile users. This utility enables a persistent call button at the bottom of the screen, allowing visitors to easily connect with your business without searching for contact information. When activated, the button pulsates subtly, inviting users to click. Upon clicking, a panel appears with the pre-filled contact number, simplifying the calling process.

Customization options include adjusting the button's appearance, such as background color and icon, to align with your website's design. Additionally, users can set specific visibility times for the button based on their office hours and chosen days of the week. This feature ensures that potential clients can reach you during business hours, effectively converting site visitors into actual customers.
