Why Does Reliance Jio Require an App for VoLTE Calling on Certain Phones?

Reliance Jio, a leading telecommunications company, mandates the use of an app for VoLTE (Voice over LTE) calling on certain phones. This requirement stems from several technical and operational considerations. Let#39;s delve into the key reasons behind this necessity.

VoLTE Support

VoLTE stands for Voice over LTE, a technology that enables high-quality voice calls over the 4G LTE network. While many smartphones are equipped with built-in VoLTE support, some may not have this feature natively. For these devices, the JioCall app serves as a crucial intermediary. It allows users to make voice calls using VoLTE even if their device lacks native support for this technology. Using such an app ensures that callers can enjoy clear and reliable voice quality, regardless of their device capabilities.

Network Compatibility

The JioCall app also ensures compatibility with Jio's network infrastructure, which is optimized for data services. By requiring the app, Jio can provide a consistent calling experience across various devices. This ensures that users, regardless of the device they own, can communicate effectively and have a seamless calling experience. Additionally, the app helps in maintaining the quality and reliability of voice calls, which is critical for customer satisfaction.

Feature Access

The JioCall app offers additional features that may not be available through the standard dialer on unsupported devices. These features include video calling and messaging. By providing these services through an app, Jio can enhance the user experience and offer a more comprehensive communication platform. These features are particularly beneficial for users who might not have the necessary hardware for these functionalities but want to access them for convenience and ease of use.

Regulatory Compliance

In some cases, the JioCall app helps meet regulatory requirements for call routing and quality. Ensuring that calls are properly managed on the network is crucial for compliance with local and international communication standards. By using the app, Jio can ensure that calls are handled in a manner that adheres to these regulations, thereby reducing the risk of legal issues and enhancing its reputation as a reliable telecom service provider.

Understanding LTE and VoLTE

To fully comprehend the necessity of the JioCall app, it is important to understand two key terms: LTE (Long Term Evolution) and VoLTE (Voice over LTE).

LTE (Long Term Evolution) is a more popularly known as 4G. It refers to a standard for wireless communication for mobile networks. LTE is designed to improve the wireless broadband experience with high data rates, low latency, and reliable connectivity. The widespread adoption of LTE has made it the de facto standard for 4G networks.

VoLTE is a technology that allows voice calls to be made over the 4G LTE network, rather than traditional 3G or 2G networks. VoLTE provides higher voice quality and can handle more simultaneous calls efficiently. However, not all phones are VoLTE enabled. If a phone is LTE enabled but lacks VoLTE support, it needs an app like Jio4GVoice to access the VoLTE option.

If a phone is VoLTE enabled, it can utilize the default apps for making and receiving calls and text messages without any additional software installations. The Jio4GVoice app is specifically designed for devices that do not have VoLTE built-in, ensuring that they can still take advantage of high-quality voice calls through the 4G network.
