Sprint could be getting ready to introduce Wi-Fi calling for two Samsung devices at launch.
According to a training manual obtained by Android Central, Wi-Fi calling and texting will first come to the Samsung Galaxy S4 mini and Galaxy Mega at an unspecified launch. This feature supposedly will be unlocked with a downloaded "maintenance update."
In addition to the two Samsung handsets, new devices running Android 4.2 and above will be able to cash in on 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 training manual documents that users enable the feature by visiting http://sprint.com/manage on a compatible device. To turn it off, users can toggle the feature in the settings of "approved" Sprint Android devices.
While that’s good and all there are still restrictions. Wi-Fi calls will only be supported domestically within the continental United States, U.S. Virgin Islands, and Puerto Rico.
Android users will also have to turn on their Location Services in order to ring in over the net. In one last line item, calls started over CDMA can’t be switched over to the Wi-Fi channel or vice-versa.
Precious voice minutes
If Sprints Wi-Fi calling really happens, the yellow carrier will join the ranks of T-Mobile and Virgin Wireless.
Virgin is able to serve both Android and iOS handsets through its SmartCall App. Meanwhile, T-Mobile has had free Wi-Fi calling for Android devices since 2010.
Sprint has not released an exact timetable for when it’s roll out Wi-Fi calling. But, it has a lot of catching up to do if it can’t retroactively enable the feature on older devices.
