Once upon a time, communication between people was largely dependent on SMS（ Because it's too expensive to call ）That few hundred words carry countless emotions. But since the advent of the Internet era, especially after the popularity of high-speed networks, few people have sent text messages to chat with relatives and friends. From the elderly to children, they use WeChat, QQ and other communication software.

On December 3, 1992, 25 years ago, the first text message was sent from an engineer's computer to Vodafone's boss's mobile phone. The message was "Merry Christmas". In 2000, the United States sent an average of 12 million short messages every month. By 2006, the number had gone to 12.5 billion, 45 billion in 2007, and 781 billion in 2017.

Although it seems that there are many, SMS is also facing challenges from many applications in the United States, such as WhatsApp, Facebook Messenger and iMessage. In China, the cost of sending a short message is 0.1 yuan, while the cost of using WeChat and other software is 0 yuan, so the traditional short message service is becoming increasingly unpopular. Do you still send short messages today?
