Using the 5G network, China Telecom’s customer service said: Only the latest 5G mobile phone can be replaced.

According to the Chinese media “The Paper”, Mr. Wang from Sichuan stated that he bought a Mi 9 Pro 5G mobile phone with more than 4,000 yuan under active lobbying by China Telecom staff six months ago, but recently the new mobile phone always cannot receive 5G signals. , Can only use 4G network. In this regard, China Telecom’s customer service said that Sichuan Telecom’s 5G network base station has been upgraded from the previous NSA mode to a SA mode 5G base station.
