How many Chinese characters can a short message send?

A short message can send at most 140 bytes, which means that a short message can send at most 70 Chinese characters.

Some mobile phones can send and receive hundreds of words at a time, and some mobile phones can only send and receive 70 words at a time, which is only related to mobile phones. However, these hundreds of words are no longer short messages, but are split and sent according to a short message of 70 Chinese characters. If there is a word 150, it has actually been divided into three short messages according to 70 words, 70 words and 10 words, and the service fee for the three short messages has been charged.
