The state-owned telecommunication service provider, Nepal Telecom (NT), has recently launched the VoLTE service for its users. It has been testing VoLTE service as it has also started the expansion of the 4G into more areas of Nepal. The 4G service of the NT is now available in all 77 districts of Nepal. But, on the occasion of World Telecommunications and Information Society Day, it has officially launched the VoLTE service. This service provides HD voice and video calls over the 4G network.

Let’s know what this VoLTE service is all about.

What is VoLTE?

VoLTE stands for ‘voice over LTE’. It is an advanced technology that delivers high-quality lifelike sound over voice calls across the NT 4G network. It is similar to the voice over IP (VoIP), which means the voice passes through the data network for the voice service. VoLTE has up to three times more voice and data capacity than older 3G networks and up to six times more than the 2G GSM networks. It uses less bandwidth but is charged the same rate as other calls.

What does VoLTE provide?

Voice calls have been one of the most used forms of communication in Nepal. It is also one of the primary services that any telecom provides and generates huge revenues from it. There is a number of benefits users can get from the VoLTE services.

1. Video calls

One of the great functions of this service apart from HD voice calls is the user will be able to switch to video calls without the need to switch their data on. This service currently is available only for a limited set of smartphones. This service also allows switching between the call and video just like OTT apps such as Messenger, Viber, and Whatsapp etc.

2. Superior call quality

A big advantage of switching to the VoLTE service is that the call quality is way superior to that of 3G or 2G networks. More data will be transferred over 4G than 3G or 2G networks, making it easier not only to understand what the person on the other end is saying but also their voice of tone. It is an HD voice call that gives a richer experience.

3. Faster data

Since there is no need to switch to a 3G network when making a call with VoLTE, you can use the 4G simultaneously for other functions on your phone while on a call. This can be very handy while you are multitasking. The gamers who use the data over wifi will have a better idea of this. They can now enjoy their games and have a conversation over a call at the same time through this service.

4. Constant switch

This service also offers the ability to seamlessly move between the network and wifi without the call cutting out. You can seamlessly have a conversation even when switching from a cellular network to wifi.

5. Better battery life

VoLTE also provides a better battery life to smartphone users during calls. Before this system was in existence, the phone had to switch the network from 4G to 3G or 2G during the calls since 4G calls were not supported. The constant switch in the network would mean the constant search for a different signal each time which could consume the battery of your smartphone.

So what does it require?

The first thing you need to have is a smartphone that supports a 4G network as well as VoLTE support. Not every 4G phone has the VoLTE service enabled. Some of the smartphones compatible with NTC VoLTE services are:

  • You should make sure that you have a 4G-enabled sim card.
  • Make sure that your device has been upgraded with the latest software provided by the manufacturer.
  • If you have a dual-sim handset, make sure your NT 4G-sim is inserted in the sim slot with data capability and network mode as 4G/3G (Auto).
