As we all know, VoLTE technology can enable voice and data services to be carried on 4G networks at the same time, and achieve high-speed mobile Internet access and high-definition voice/video calls, especially when mobile and telecom calls do not have to fall back to 2G networks.
However, China Mobile's VoLTE has been in business for a long time in the country, and Telecom and China Unicom have been testing internally, so that users can wait. Although some areas have been quietly opened in a small area, they can be opened, but they are only a "beta version", and they are not safe to use. Now, China Telecom has finally officially commercialized VoLTE, and telecom users can immediately log in to the telecom official website or mobile business hall to open.
However, the first batch of telecom VoLTE was only opened in 10 provinces and cities nationwide: Jiangsu, Guangdong, Fujian, Sichuan, Hunan, Anhui, Zhejiang, Hubei, Yunnan, and Shanghai. Telecom said that other provinces and cities will open VoLTE.
According to netizens' pro-test, the telecom VoLTE can be successfully opened, and the Internet or call experience is greatly improved.
