How to Activate VoLTE Service in NTC SIM and Get 100 Minutes Free Voice Call

Nepal Telecom has announced the beginning of VoLTE (Voice Over LTE) service on 17 May, 2021. NT has announced the trial beginning of VoLTE service on the occasion of World Telecommunication & Information Society day. VoLTE will enhance the call quality as well as reduce the connection time.

The VoLTE service will be free of cost. With the announcement, NTC have also offered 100 minutes of free voice call in NTC SIM over VoLTE. But before knowing the process to get the free offer, first let’s understand something about the VoLTE service.


What is VoLTE?

VoLTE (Voice over LTE) is an IP-based data transmission technology. VoLTE technology delivers both call and data services at once over a 4G network.

That means you can make calls and access the internet through mobile data at the same time. If your phone supports dual SIM and dual VoLTE, you can receive a call on a SIM card even when the other SIM card is already on a call.

VoLTE also provides you with faster call connection time and higher quality calls. With VoLTE we can experience ultra-clear voice quality with reduced background noise. Conversations will sound more natural. As expected, both must have VoLTE enabled for higher quality voice and video calls.

What are the requirements for using VoLTE?

To enjoy VoLTE services, you must meet the following conditions

  • You must need to have a VoLTE service available on mobile with the latest software updates.
  • Own an NTC 4G SIM on a mobile device.
  • The VoLTE voice calling feature has been enabled on your smartphone.
  • The preferred network must be 4G/3G/2G or Auto.
  • You must have access to Nepal Telecom’s 4G network coverage.
