Digi has introduced Voice-over-LTE calls for all its customers. This is being made available over its 4G LTE network, and promises a better call quality for those capable of using the feature. Needless to say, not every smartphone is VoLTE capable; although Digi is working on expanding the range.
VoLTE allows voice calls to be placed over the LTE spectrum, instead of having the phone default to 3G or 2G bands. In addition to providing better call quality, this also has the side effect of allowing background downloads to continue at 4G speeds. It’s minor, but rather significant, benefit for those who are used to using internet tethering.
“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,” said Digi’s Chief Marketing Officer, Loh Keh Jiat.
For now, Digi’s VoLTE is only available on the iPhone 7 and 7 plus. Users of the iPhone 6, 6 plus, 6S, 6S plus and SE can also enable VoLTE calling provided that they have upgraded to iOS 10.1. Digi has said that it is working on adding more devices to this list, but it will come in stages at a later date.
There are no extra charges for using VoLTE, and those with compatible devices should begin seeing it very shortly.
