T-Mobile Will Keep MetroPCS's VoLTE Service Alive
T-Mobile USA CTO Neville Ray said that it will keep the voice over LTE service offered by MetroPCS up and running, at least in the short term, once the companies are merged. Speaking to GigaOm, Ray said, "We will certainly support the VoLTE services that MetroPCS has today. But is that the VoLTE we want to populate the new network with? TBD." T-Mobile will eventually move its voice traffic to an all IP network, but it is not in a hurry. "The rush to get to VoLTE is less for T-Mobile because we have such underlying strength on GSM and HSPA+," said Ray. MetroPCS has less capacity on its network for voice and data services together. It was the first carrier to launch VoLTE in the U.S. T-Mobile USA and MetroPCS are to be merged, as long as Deutsche Telekom, T-Mobile USA's parent company, is able to score the necessary regulatory approval. T-Mobile plans to migrate MetroPCS's CDMA customers onto its GSM network, shut down the CDMA network, and then refarm that spectrum for its own 4G network.
