DOCOMO Pacific has disclosed plans to launch the first VoLTE services in Guam and the Northern Mariana Islands, with the enhancement set to go live in July for all users with VoLTE-capable devices. On 19 June DOCOMO Pacific engineers made the first commercial VoLTE call on Guam and the following day they made the first VoLTE call to Saipan, the largest of the Northern Mariana Islands.
The press release notes: ‘VoLTE allows the efficient use of network resources, helping to lower operational costs. With the use of VoLTE, voice traffic is routed over the 4G LTE network used to transmit data, freeing up spectrum for the 5G technology that DOCOMO Pacific will launch soon.’
In March this year the telco launched its DOCOMO 5G Open Lab on Guam, providing a testbed for international partners and local businesses to trial 5G solutions.
