Two months back, China Telecom launched the E-surfing Quantum HD secret call feature that ultimately supports the VoLTE HD encrypted calls. Fortunately, Huawei device users will also get the chance to enjoy this feature. As per the reports, Huawei Mate 40E will now get the support of quantum SIM cards with domestic chipsets.
China Telecom has initiated an online reservation program that brings this encrypted calling feature to more devices. Besides, it enhances the function with domestic customizations, making the user experience rich and comfortable.
Let’s talk about this new E-surfing Quantum HD secret call feature in more detail.
The thoughtful feature powers with a customized terminal developed by China Telecom. Moreover, it gives space to quantum security SIM and supports localized processors with easy-personalized modules. Thus, users get capable of enjoying a secure and high-definition VoLTE quantum encrypted call.
Furthermore, the feature follows the national secret algorithm – Triple Protection. Consequently, this means that the amazing feature provides the users with pipe-end-core integration. Hence, users will experience better security protection as well as a new form of technology and communication.
For the moment, the feature is coming with Quantum SIM cards for Huawei Mate 40E, Huawei Huawei Mate 30 Pro, and Huawei Nova 8 smartphones. But the company will push this function to more models in the time ahead.
How to use the Quantum HD secret call feature?
For using this feature, you do not have to install any third-party application. However, you need to keep some points in your mind while you take action on the feature. Here are some important points to note:
- Every time a user starts off a “quantum secret call”, the key in the card will randomly capture the user’s identity.
- After the authentication gets completed, a new key will appear at the same time through the quantum network to encrypt the session data.
- The particular key gets discarded as soon as the call ends.
- The encryption and decryption of VoLTE voice data assure to prevent monitoring of calls during network transmission.
- The process requires both parties to mandatorily use the quantum SIM cards and chips for successful call completion.
Fortunately, the mentioned function does not reduce the quality of the call. It maintains the voice clarity of the original telecom VoLTE service. Moreover, users can directly switch to encrypted calls via dial pad. Besides, if any party in this process, does not consist of the function, then the call will automatically appear on the original VoLTE network, fastly and conveniently.
To mug up, the feature increases the security as well as the confidentiality of the calls between users. Currently, only a few devices are compatible with this feature. But we are looking forward to this function soon in every Huawei smartphone.
