In which year did China Mobile SMS function start?

1992, the world's first short message was successfully sent to a mobile phone in Wolfen, England through a PC on the GSM network, thus announcing the birth of mobile phone short messages. The birth of the first short message in China is unknown, but according to research, the mobile communication network in China had the short message function as early as 1994, but people with mobile phones didn't need the short message function at that time.
