VoLTE (Voice over Long Term Evolution) is an advanced 4G feature that provides provide HD voice calls over an LTE network. As known, Nepal Telecom is going to launch VoLTE after rigorous testing which it has been doing since it started expanding 4G to more areas. Ntc 4G service is being available in all 77 districts, so VoLTE will also launch all over the country.
Since 4G is data-only technology, Telecom companies require extra features to support voice over 4G or fall back to the existing legacy networks like 2G, 3G while being on 4G.
VoLTE (Voice over LTE) is an extra feature solution to provide Voice over 4G LTE. Since voice passes through the data (IP) network for the voice services, it is similar to Voice over IP. This service
Just like OTT applications (Skype, Viber, Messanger), the VoLTE allows you to call using your own number through 4G. There is an expectation with this service that the voice call becomes free. But it’s unrealistic for a country like Nepal now. So, the telcos in Nepal will charge the calls through the service at a cost per minute.
Nepal Telecom has recently invited smartphones companies to perform VoLTE test on their handsets. Nepal Telcom 4G supports two bands i.e. band 3 (1800MHz) and Band 20(800MHz). So, this testing also involves various other features of Ntc’s 4G LTE network.
Voice over LTE technology (VoLTE) provides HD quality voice call through a 4G network. So, to test those 4G bands, VoLTE, and more, Nepal Telecom aims to collaborate with the Smartphone vendors/distributors. They will also list the supporting handsets in their website after the test.
Advantages of VoLTE:
Here are some of the advantages of VoLTE:
- Crystal Clear Voice with low noise
- Faster Call setup
- Longer Battery life
- Additional service of Video calls using ViLTE
For a telecom operator also, VoLTE is advantageous, as it enables a new operator to provide the voice with their 4G network. This is what Jio did in India, as a green field telecom operator. Whereas the existing ones can also provide Voice and high-speed internet with 4G network on no-coverage zones.
VoLTE in Nepal
As per the latest information, Nepal Telecom will launch VoLTE on a massive scale after sufficient testing and developing their network. We can expect Ncell might also bring the VoLTE service in near future, but there is no any news or rumours about it till now.
This feature is idle for the upcoming telcos to be a 4G only operator while providing Voice using VoLTE. It is mostly useful for the upcoming operators like UTL, CG Telecom, Smart Telecom etc.

Likewise, you also need to enable VolTE for your SIM. Similarly, on the customer end, you need to have VoLTE support on your smartphone. As every 4G phones don’t have VoLTE enabled, you need to make sure your operator and your smartphone support the service if you want to use the service.
