In what year did China Mobile Phone (Simulator) officially start operating?

The era of simulated mobile phones in China can be roughly counted from the beginning of China Mobile Communications Group Company's operation of 1987 simulating mobile telephone service at 900MHz to the end of June 30, 2006 when China Mobile Communications Group Company completely stopped the international and domestic roaming business of simulated mobile phone network customers.

As for when and where the first short message in China was born, it 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 it at all. With the increasing popularity of mobile phones, since 1998, China Mobile and China Unicom have expanded their SMS services on a large scale.
