VoLTE, sometimes also known as HD Voice, is a technology that brings voice calls over a 4G LTE network. The higher bandwidth of 4G LTE networks make it ideal to transmit higher fidelity voice calls than over the 2G and 3G networks. Along with that, VoLTE also brings with it noise cancellation capability. Both features are dependent on the mobile devices used for voice calls. 

Another advantage of VoLTE is it allows customers to simultaneously surf the web, download or stream content from the internet at 4G LTE speeds while engaged on a voice call. Currently, the need to use 3G or 2G infrastructure to connect voice calls means internet activity will drop to slower speeds.

The Telco has been testing VoLTE since late 2015 using solutions from network vendor, ZTE Corporation. Digi’s current 4G LTE and 3G network are mainly deployed by ZTE.

At the moment, Digi VoLTE is only available on iPhones running iOS 10.1:

  • iPhone 7 / 7 Plus
  • iPhone 6s / 6s Plus
  • iPhone 6 / 6 Plus
  • iPhone SE

Digi said VoLTE capability in devices from other manufacturers will be rolled out soon in stages but no further details were given.

“We are excited to bring this next-generation technology to customers. VoLTE is an evolution of voice call technology. We have been placing voice calls on the 2G and 3G network for years now and it’s a natural shift that we’re bring the higher capacity of our 4G network to offer customers a higher quality call experience.”

“We have been working hard to bring innovation to the market and VoLTE is one of the many things we have in the pipeline for our customers. This is yet another step forward as we move towards our ambition of becoming our customers’ favourite partner in digital life,” said Digi’s Chief Marketing Officer, Loh Keh Jiat.

To enjoy these new features, which come at no additional cost, both devices making and receiving the call must be VoLTE-capable with the feature switched on and with both customers located within Digi’s 4G LTE coverage area. Digi said its 4G LTE network now reaches 78% of Malaysians nationwide in 225 major cities and towns making it widely accessible for those with the appropriate devices to enjoy an improved call quality.
