Since the first SMS message was sent almost 30 years ago, SMS has revolutionised the way we communicate with each other. Many people think of SMS as old-fashioned and outdated, but in fact it's still one of the most widely used forms of communication, despite smartphones and Instant Messaging Apps. In other words, SMS can easily compete with the younger and smarter players in the industry.

In this article, we celebrate that SMS is still one of the most reliable and accessible forms of communication. We've found some fun and quirky facts you probably didn't know about SMS. Enjoy reading.

1. The first SMS message was a Christmas greeting

The first SMS message was received in the UK in 1993 by Richard Jarvis and was sent by 22-year-old software programmer Neil Papworth wishing him a Merry Christmas. The SMS message was sent via computer, as mobile phones didn't have a keyboard at the time.

2. Postcards and random sentences on a typewriter helped determine the length of an SMS message

In 1985, German engineer Friedhelm Hillebrand was tasked with determining how many characters an SMS message should contain. He sat down at a typewriter and wrote a bunch of random sentences. It turned out that the sentences averaged 160 characters. He also analysed a stack of postcards that together had an average length of 150 characters. Based on this, it was decided that an SMS message should be 160 characters long. This is still true today. However, it is now possible to merge up to 9 SMS messages so that it looks like one single message to the user.

4. 75% prefer receiving an SMS message to making a call

8. SMS has formed the basis for a new language

SMS has brought about a whole new language, where communication is done with abbreviations and emojis like “Can we tlk?”. Primarily, it is a relic from when you had to stay under 160 characters in one SMS message, but it also represents the way we communicate today, which is fast and 'on the go'.

10. Twitter is inspired by SMS

Twitter, which was launched in 2006, was directly inspired by SMS with the golden limit of 140 characters in a tweet. The limit was set to keep the platform simple and accessible to all users, just like SMS. When you add the 20-character limit for Twitter's username to the 140 characters in a tweet, you get 160 characters.
