How many words do you charge for sending SMS?

Each mobile short message is more than 70 words, and the charge is 0. 1 yuan. At the beginning of the short message service, each message is at most 140 characters, that is, 70 Chinese characters.

At present, mobile phones may support many words, hundreds of words and so on. And you can send it out, but it's still 70 words apart. But in fact, it is necessary to split and repackage the super-long short message and add an extra header. In fact, 67 Chinese characters count as a short message.
