How many words is a mobile phone message?

At present, the short message service of each mobile communication company is charged according to 70 characters, that is, a short message (including punctuation marks) takes 70 characters as the charging unit and is calculated cumulatively.

For example, if you send a message with 170 characters (including punctuation), the operator will divide the message into: 170=70+70+30, which means you will be charged for sending three messages. Although many mobile phone manufacturers also set the interface of "writing short messages" on their mobile phones as a writing interface of several hundred words, the length of sending short messages is not calculated according to the length of short messages that the mobile phone can write, so when sending, the mobile phone short message system will automatically truncate the length of a short message in English or numeric characters of 140, which is about 70 Chinese characters, and charge a fee by converting it into "number of paragraphs".
