DOCOMO PACIFIC set to launch first VoLTE services for Guam and the CNMI

Tamuning, Guam (June 27, 2019)— As part of the rollout of the next generation of wireless technology, DOCOMO PACIFIC is preparing to launch the first VoLTE services in Guam and the CNMI.


VoLTE or Voice over Long-Term Evolution allows customers to place a phone call over your LTE connection instead of the traditional voice network, resulting in High-Definition (HD) Voice services providing clearer audio quality.


VoLTE lets you experience HD Voice calls with minimal background noise, making it much easier and clearer for both people on a call to hear one another. The mixture of voice and data to make calls will produce faster call setup times and quicker connections. Additionally, VoLTE services are less power-intensive than calls being made over a 3G connection, resulting in better battery life.


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.


On June 19th, DOCOMO PACIFIC engineers made the first commercial VoLTE call on Guam and the following day they made the first VoLTE call to Saipan. The commercial launch of VoLTE services will begin to roll-out in July 2019 for VoLTE capable devices on DOCOMO PACIFIC’s network. VoLTE services will be an added value to our existing services and will not come at any additional cost.

DOCOMO PACIFIC is excited to be the first to bring another innovative service that improves the voice quality of calls for our customers in the Marianas. VoLTE is the future of voice communications and we can’t wait for our customers to have a higher quality experience while talking with family and friends. As we prepare to launch 5G technology soon, VoLTE is another step in our journey to be the technology leader and bring the best and fastest services to our customers.
