Nepal Telecom Introduces VoWiFi Service: Everything You Need to Know

Nepal Telecom has officially launched its Voice over WiFi (VoWiFi) service, marking a significant step toward enhancing communication accessibility in areas with weak cellular networks. This new feature, introduced on the company’s 21st anniversary, enables users to make calls and send SMS through a WiFi connection, eliminating the need for a strong mobile signal.

What is VoWiFi?

VoWiFi, or Voice over WiFi, is a technology that allows users to make phone calls and send text messages using a WiFi network instead of relying on cellular towers. Unlike traditional VoIP services like WhatsApp or Skype, VoWiFi operates using a mobile number, ensuring seamless connectivity without requiring third-party applications.

How Does VoWiFi Work?

The technology utilizes a WiFi connection to route voice calls and messages through the internet. This means that even in locations where mobile network coverage is weak or unavailable, users can stay connected as long as they have access to a WiFi network. VoWiFi differs from VoLTE (Voice over LTE), which uses a 4G network for high-quality voice transmission.

Benefits of VoWiFi

• Improved Call Quality: VoWiFi provides a stable and high-quality calling experience in areas with poor mobile network reception.

• Extended Coverage: Calls can be made in remote locations, underground spaces, or buildings with thick walls where cellular signals struggle to reach.

• Cost-Effective Communication: The service uses existing WiFi connections, reducing dependency on mobile network towers and saving costs on voice calls and SMS.

• No Additional Apps Required: Users can continue using their regular mobile number without needing any third-party applications.

• Longer Battery Life: Since VoWiFi doesn’t rely on cellular network signals, it helps conserve battery life.

• International Usage: Nepal Telecom users abroad can utilize VoWiFi to make calls to Nepal without incurring standard international roaming charges.

Drawbacks of VoWiFi

Despite its advantages, VoWiFi has some limitations:

• WiFi Dependency: Call quality and stability depend on the strength and reliability of the WiFi network.

• Device Compatibility: Not all smartphones support VoWiFi, and some may require specific software updates from manufacturers.

• Interference Issues: As WiFi operates on an unlicensed frequency, interference from other devices may impact call quality.

• Limited Responsibility of Service Providers: Unlike mobile networks, telecom operators are not responsible for maintaining WiFi networks, making service reliability dependent on the user's internet connection.

VoWiFi Availability in Nepal

Nepal Telecom launched VoWiFi on Magh 22, 2081, and the service is now accessible to compatible devices. Currently, private telecom operator Ncell is also working on infrastructure to introduce VoWiFi in the near future. Some smartphones, including models from Xiaomi, Samsung, Apple, Oppo, and Realme, already support VoWiFi, though users may need to activate the feature manually. For instance, Xiaomi users can enable VoWiFi by dialing ##86583## to disable carrier checks.

VoWiFi vs. VoLTE: Understanding the Difference

While both VoWiFi and VoLTE enhance voice call quality, they operate differently:

• VoWiFi relies on an internet-based WiFi connection to transmit calls and messages.

• VoLTE uses a 4G LTE network to provide high-definition voice calls.

Both technologies improve voice clarity and call stability, but VoWiFi is particularly beneficial in areas with limited cellular coverage.

Future of VoWiFi in Nepal

As Nepal expands its digital connectivity, VoWiFi is expected to play a crucial role in bridging communication gaps. While the service currently depends on internet availability, further improvements in WiFi infrastructure and telecom partnerships will enhance its effectiveness. As telecom operators integrate VoWiFi with their existing networks, users can expect a more seamless and cost-efficient communication experience.

With the successful launch of VoWiFi, Nepal Telecom aims to make modern communication more accessible, especially in areas with weak network coverage. As more users adopt this technology, it has the potential to revolutionize the way people connect, both domestically and internationally.
