Sprint has begun offering customers VoLTE service. VoLTE allows for higher-quality voice connections when the call is passed over the LTE data network, rather than the legacy voice network. VoLTE has been available from AT&T, T-Mobile, and Verizon Wireless for years. Sprint already offers a high-quality VoIP service called Calling Plus. Sprint's new VoLTE service replaces Calling Plus, which is being phased out. "Before we do updates market-by-market on various devices, we are alerting Calling Plus customers so they can decide whether to continue using the feature until our VoLTE launch is complete," said Sprint in a statement provided to The Verge
. Right now, VoLTE is only availably to the Samsung Galaxy S8, S8+, and S8 Active. It is limited to just 15 markets, including Atlanta, Chicago, Dallas-Ft. Worth, Houston, Indianapolis, New York City, Philadelphia, Pittsburgh, San Francisco, and Washington, D.C. Sprint did not say how quickly VoLTE will be made available to additional phones and markets.
