Mobile Minute: Wi-Fi calling could come to Sprint

Sprint could be the next major carrier to offer free calling over Wi-Fi. T-Mobile US has offered Wi-Fi calling for several years on certain phones, and now Android Central is reporting that Sprint is preparing to launch Wi-Fi calling on the Samsung Galaxy S4 Mini and the Samsung Galaxy S Mega, as well as on future Android devices that support Android 4.2 and better. Sprint training documents apparently detail the plan, and say that Wi-Fi calls will only work when a CDMA signal is present, in order to ensure access to 9-1-1. Users will not be able to move between Wi-Fi and CDMA on the same call, and the service will only work in the United States, the U.S. Virgin Islands and Puerto Rico.
