If you look at the top of your phone, you'll usually see a little symbol that says 3G or 4G. The "G" stands for the "generation" （代） of your mobile network. But the symbols will become things of the past after 5G networks fully arrive.
On March 30, Shanghai vice-mayor Wu Qing made the first 5G video call on a Huawei Mate X Smartphone. Shanghai has also become the first city in China to start testing 5G networks.
