It can be difficult to determine the length of the world’s longest text message due to the lack of an official record or standard for measuring it. However, there have been instances where individuals have sent exceptionally long text messages for various reasons.

One such instance occurred in 2016 when a man named Nick Herbert from the UK was frustrated with his son’s lack of response to his messages. To address this issue, he developed an app called ReplyASAP that would take over the screen of his son’s phone and send a loud alarm until he responded. To promote the app, Herbert sent a text message to his son that was over 1,000 words long. The message described the app’s features and benefits, and served as a warning to his son to respond promptly to his messages.
In another instance, a woman named Li Yuan from China sent a text message that was over 17,000 words long in 2017. She was feeling depressed and decided to express her emotions in a message to her ex-boyfriend. The message went viral in China and Yuan became known as the “17,000-word girl.” She poured her heart out in the message, detailing the pain she felt from their breakup and expressing her hopes for reconciliation.
Text messages have also been used to write entire novels. In 2008, Yutaka Tsujino from Japan wrote a novel called “Fujoshi no Tsuzui-san” entirely in text messages. The novel was over 2,000 pages long and consisted of over 1.5 million characters. Tsujino sent the novel to his friends over the course of two years, with each text message containing a few pages of the story.
Similarly, Marcelo Santos III from the Philippines wrote a book called “Para sa Hopeless Romantic” in text message format in 2012. The book was about the romantic struggles of a group of young people and was written in the colloquial language used by young Filipinos. It was a commercial success and was later adapted into a movie.
While these examples are impressive in their length and creativity, it is important to note that practical limitations to the length of text messages exist. The standard limit for a text message is 160 characters, although this can vary depending on the carrier and device being used. In order to send longer messages, special apps or software that can divide the message into multiple parts and reassemble them on the receiving end may need to be used. This can be inconvenient for both the sender and receiver, as it can make it difficult to read and respond to the message.
In conclusion, while there is no official record for the world’s longest text message, there have been instances where individuals have sent exceptionally long messages for various reasons. These messages have ranged from practical apps to emotional outpourings to entire novels. However, it is important to remember that the practical limitations of text messages make it difficult to send messages that are too long, and there are better methods of communication for conveying large amounts of information.
