What is VoLTE?
1O1O is proud to present you VoLTE, which brings voice call and video call to a brand new generation! VoLTE (Voice Over LTE) means connection of voice and video call through 4G LTE network. As a valuable 1O1O customer, you can now enjoy a FREE upgrade to experience voice call with speedy connection and video call with high quality!
Benefit of using VoLTE
1-second call connection
Make substantially faster voice-call connections. Effecting a traditional 3G call connection takes an average of 7 seconds, but can be done in just 1 second when using VoLTE.
Greater voice quality
VoLTE significantly enhances voice quality, especially with our expansive network coverage.
Simultaneous voice and high-speed date usage
You can use data for other functions while on a call – eg browsing or downloading an app. This capability enables you to multitask.
Seamless switching between VoLTE and VoWiFI
VoLTE has the ability to switch seamlessly between LTE and Wi-Fi calling, without your call dropping out.
12 times better video-call quality
Ensures high-definition video calling (applicable only to some Android handsets). A VoLTE connection provides clear picture quality without grids, because resolution is up to 640 x 480 pixels. As a comparison, resolution for 3G network video calls is just 176 x 144 pixels.
Seamless switching between voice and video calls, plus better battery life
Switch between a voice and video call instantly with just one click (applicable only to certain Android handsets), whereas switching from 3G to 4G involves a delay. A spin-off benefit is longer battery life.
Ensure normal voice service – Please enable VoLTE now
As many popular travel destinations (e.g. Japan, South Korea and Taiwan) have fully shut down 2G/3G network services, VoLTE has become the main standard for voice calls. If your phone does not support or has not enabled VoLTE, you maybe unable to make or receive voice calls when travelling locally or overseas.
