According to supposed leaked internal documents at Sprint, it looks like the Now Network might just be gearing up to follow in T-Mobile's footsteps yet again. For a while now, T-Mobile has had WiFi calling in sparse limited areas around the country. The leaked docs suggest Sprint might soon rollout the same type of service.
For those unfamiliar with WiFi calling, it basically allows users to make phone calls over WiFi without ever using their cellular data plan at all. The leaked memo suggest that Sprint will confer maintenance updates on their Samsung Galaxy S4 Mini and Galaxy Mega which will enable the WiFi calling feature. Here's a quote with more of the details,
While this could be a handy feature for some users, it makes us pause and wonder a bit. Most users on Sprint will likely have one of their plans which includes unlimited minutes. This leaves little room for value with such a feature. Please share your opinion of how and why this functionality would still be useful.In order to take advantage of Wifi Calling, a customer will simply need a compatible device, enable the feature through a web interface, Cell Phones, Mobile Phones & Wireless Calling Plans from Sprint, and begin using it. No monthly charge will be assessed for turning on Wifi Calling. The training materials indicate that there will simply be a Wifi Calling toggle in the settings of "approved" Sprint Android devices going forward.
An interesting wrinkle here is that you must have Android Location Services turned on in order to make Wifi calls, and that it will only be a supported feature within the U.S., U.S. Virgin 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.
