Read the full text of another short message.

If there are more than 70 Chinese characters, the fee for the second message will be charged. Whether the other party receives one or more messages depends on the mobile phone.

In the past, the old receiver did not support long short messages, and sending or receiving was separated. Now more than 70 Chinese characters sent by mobile phones have also been received and will not be separated.

160 English characters should be expressed in 7-bit ASCII code, which requires 7× 160 bits. However, if it is changed to 8-bit UCS-2 coding, it needs 7× 160÷8 bits. At the same time, because Chinese characters need to occupy two characters, the total number of Chinese characters is 7× 160÷8÷2, which is exactly equal to 70.

Extended data

Short messages of more than 70 words are long messages, and mobile phone users see one. The actual gateway will charge according to multiple words, once every 67 words.

The above is the difference between normal SMS and long SMS billing. When users actually use the short message group sending platform, long short messages can carry more information, and mobile phone users have a better reading experience after receiving short messages.

But in terms of reading habits, short messages are more suitable for brevity, so when editing short messages, you can be as brief as possible. China's writing is extensive and profound, with few words, but it can actually express profound meanings. This is another cultural background that Weibo and light blog are popular in China.
