Sprint officially announced on Friday that it will be bringing its free Wi-Fi calling service to the Samsung Galaxy Mega and the Galaxy S4 mini, with plans to add more devices later this year.
An over-the-air update is required before the service will be enabled, and Sprint says that update will be rolled out over the next few weeks.
Wi-Fi calling is beneficial for users who don’t have proper network coverage in their home or office and will allow users to make phone calls and send text messages using their local Wi-Fi networks rather than relying on mobile networks.
In order to take advantage of Wi-Fi Calling, a customer will simply need a compatible device, enable the feature through a web interface, and begin using it. No monthly charge will be assessed for the use of Wi-Fi Calling.
According to Sprint, Android Location Services must be turned on in order to make Wifi calls, and the feature will only be available within the U.S., U.S. Virigin Islands and Puerto Rico.
Sprint explicitly states that Wifi Calling will not be approved or supported from other locations or while using a VPN. Outbound calls over Wifi won’t be allowed without a CDMA signal present either — Sprint claims this is for 911 reasons.
