Sprint could be getting ready to introduce Wi-Fi calling, starting with two Samsung devices.
In addition to the two Samsung handsets, new devices running Android 4.2 and above will be able to cash in on Sprint's Wi-Fi calling.
As the name suggests, Wi-Fi calling allows users to get off the Sprint network and make VoIP calls and texts at no additional monthly charge. A useful feature when you're running low on minutes or in the basement of a building with no bars and a healthy Wi-Fi connection.

The service may sound like a win-win, but there are still restrictions. According to the training doc, Wi-Fi calls will only be supported domestically within the continental United States, US Virgin Islands, and Puerto Rico.
Android users will also have to turn on their Location Services in order to ring in over the net. And one last line item - calls started over CDMA can't be switched over to the Wi-Fi channel or vice-versa.
Virgin can can serve both Android and iOS handsets through its SmartCall App. Meanwhile, T-Mobile has had free Wi-Fi calling for Android devices since 2010.
