VoWiFi technology helps solve mobile phone signal coverage problems, China Telecom launches in four cities

News on May 18th, China Telecom announced the launch of a new VoWiFi (Voice over WiFi) service, which will be launched first in four cities: Guangzhou, Shenzhen, Dongguan and Foshan. The introduction of VoWiFi technology allows users to make voice and video calls through traditional dial-up methods while connected to a WiFi network, without relying on 4G or 5G network signals.

According to ITBEAR Technology Information, China Telecom has adopted the S2b non-credit (ePDG) VoWiFi solution based on broadband user scenarios and the development of the industry chain. This innovative technology provides users with traceable VoWiFi services, complies with national regulatory requirements, and enables precise positioning of VoWiFi users and support for VoWiFi on 5G terminals.

The launch of VoWiFi is of positive significance for solving voice and text message problems caused by poor mobile phone signal coverage in residential buildings, high-rise office buildings, etc. Users only need to have a mobile phone that supports VoWiFi function and enable VoWiFi service with one click in the WiFi environment to enjoy stable and smooth voice calls and seamless network switching experience.

Currently, China Telecom has carried out live network pilot deployments of VoWiFi services with end-to-end traceability capabilities in five provinces and cities, including Shanghai, Guangdong, Sichuan, Guizhou and Zhejiang. . At the same time, China Telecom has also cooperated closely with terminal manufacturers OPPO, Xiaomi, vivo, etc. to conduct relevant terminal testing and verification, and achieved success.

The use of VoWiFi is free for users and does not require downloading any applications. Users only need to have a mobile phone that supports VoWiFi, and they can automatically switch to the 4G/5G network or VoWiFi network for voice calls when connected to WiFi. Voice calls will be deducted from the voice duration in the package, and the excess will be billed as ordinary voice calls.

The launch of China Telecom’s VoWiFi service will provide users with a more convenient and stable communication experience and solve the problem of poor signal coverage in some areas. With the continuous promotion and expansion of VoWiFi services, users will be able to more easily enjoy uninterrupted connections and high-quality communication services on full-service Gigabit networks.
