Sprint enables WiFi calling on Samsung Galaxy S4

An over-the-air update will start rolling out today for Sprint customers who have the Samsung Galaxy S4.  This update is a free service that allows customers to use home WiFi or public WiFi networks for voice and messaging.  Once this update is pushed to the Galaxy S4, WiFi calling will have to be activated in the app or settings of the phone.  This feature will work seamlessly in the background of the phone without the user even knowing.  You can read more about the details at Sprint.
