VoLTE

What is VoLTE?

csl 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 csl customer, you can now enjoy a FREE upgrade to experience voice call with speedy connection and video call with high quality!

In 2017, csl 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

(1)  Facilitates faster voice-call connections. What used to take around 7 seconds on a 3G network is now as fast as 1 second, if both parties are using VoLTE.  Even so it just takes around 4 seconds if using 3G network.
