Can I Make Voice Calls on Jio SIM with Nokia Lumia 625?

In the current landscape of mobile communications, it's essential to understand the capabilities of different networks and devices. This article delves into the intricacies of making voice calls with a Nokia Lumia 625 using a Jio SIM. We will explore why voice calls on Jio SIMs are not directly possible and explain the necessary steps to enable this functionality.

Understanding the Jio Network

Jio is a cutting-edge 4G network by Reliance Jio that operates primarily on Voice over LTE (VoLTE) technology. Unlike traditional networks, which rely on 2G for voice calls when 4G is not active, Jio's VoLTE technology completely converts voice into data. This data is then transmitted through the network, processed by Jio's systems, and forwarded as a standard voice call to the recipient.

For clarity, traditional 2G-based voice calls experienced widespread usage in the past. However, the advent of 4G and VoLTE has fundamentally altered how voice communications are handled. Most 4G networks use a combination of 4G LTE for data and 2G for voice, but Jio has opted for a fully VoLTE solution, which is why it does not support 2G fallback for voice calls.

Why Cannot Jio SIMs Be Used Directly for Voice Calls?

The primary reason Nokia Lumia 625, and any device without VoLTE support, cannot use Jio SIMs for voice calls is the missing VoLTE capability. While Jio 4G provides a seamless VoLTE experience, Nokia Lumia 625 does not natively support this technology. Hence, direct voice calls are not feasible without additional software or service modifications.

It's important to note that even with a Jio SIM, voice calls are not supported on a Windows Phone 625 out of the box. This is due to the absence of a native Jio4GVoice app in the Windows Store that would support VoLTE functionality. Until such an application is available, users on these devices will not be able to make or receive voice calls.

Enabling Voice Calls on Jio SIM with Nokia Lumia 625

To make voice calls using a Jio SIM on a Nokia Lumia 625, the following steps must be taken:

Install the Jio4GVoice app from the Microsoft Store. This app, which is designed to support VoLTE, provides the essential channel required to access Jio's encrypted VoLTE network. Configure the Jio4GVoice app properly to ensure seamless integration with the Nokia Lumia 625's hardware and software. Ensure that an active data connection is maintained while using the Jio4GVoice app to make or receive voice calls. VoLTE requires an active data connection to function effectively.

Conclusion

In summary, making voice calls on Jio SIM with a Nokia Lumia 625 is not feasible due to the absence of native VoLTE support. However, with the installation of the Jio4GVoice app and an active data connection, users can enable this functionality. Understanding these nuances is crucial for users who wish to leverage the full potential of 4G and VoLTE networks.

Keep in mind that the absence of 2G fallback in Jio means that voicemail services and other 2G-based features may not be available. It's always advisable to check the VoLTE status and ensure that your device and SIM are fully compatible.
