1992, when the world's first short message was successfully sent to a mobile phone on the GSM network in Wolfen, England, no one would have thought that this low-cost short message service, which was originally launched by telecom operators to solve the high telephone bill, would have such a huge impact on people's economic and cultural life and even politics many years later.
