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!
In 2017, 1O1O has joined forces with Macau mobile service provider CTM to launch the world’s first end-to-end VoLTE IDD service, so both sets of customers can enjoy high-quality voice and video IDD calling, plus near-instant connection.
Benefit of using VoLTE
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.
VoLTE significantly enhances voice quality, especially with our expansive network coverage.
You can use data for other functions while on a call – eg browsing or downloading an app. This capability enables you to multitask.
VoLTE has the ability to switch seamlessly between LTE and Wi-Fi calling, without your call dropping out.
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.
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.
