Don't look now, but MetroPCS has managed to become the first carrier to launch a Voice-over-LTE (VoLTE) service, beating a pair of Korean carriers by a matter of hours to earn that distinction.
MetroPCS announced that it sold a VoLTE-capable device, the LG Connect 4G, at a company-owned store in the Dallas/Fort Worth area. The buyer will be able to enjoy better sound because VoLTE enables higher-quality voice calls channeled through an LTE network rather than rely on older technologies. A device must be in an LTE area to access the feature, but MetroPCS says that calls to and from the handset will use VoLTE, regardless of the handset or network used by the other person on the call.
Though it lacks the number of total subscribers and reach as bigger carriers, MetroPCS has rapidly deployed LTE to its customers. LTE already reaches about 90 percent of MetroPCS's CDMA footprint, and the company expects to serve even more markets soon. MetroPCS delayed launching VoLTE earlier this year, but a similarly rapid expansion could enable the carrier to refarm spectrum and improve performance of its LTE network.source: MetroPCS, via: Phone Scoop
