Chinese telecom giant China Mobile has tested its first 5G-based phone call in Beijing, reports the Xinhua News Agency.

The test call came after the latest update of the company's previous 4G networks to provide 5G services, the next generation in mobile technology.

The trial is said to have completed a call with clear sound quality between 5G phones, with neither of the phones changing its previously-registered card or number for new ones to use the 5G networks.

In December, China's Ministry of Industry and Information Technology (MIIT) officially allocated frequency bands for 5G testing to China Mobile, China Unicom and China Telecom, the country's three main telecom carriers.
