As shown in the figure, you can't edit a 70-word short message. How could it be longer? The mobile phone is the butterfly of htc.

Because of the regulations of mobile operators, a short message can only have 140 bytes at most, and one Chinese character accounts for two bytes, so there can only be 70 Chinese characters at most, and English can have 140 letters.

You can change a messaging application. If the "information" program that comes with the system can only input 70 Chinese characters, you can go to the next "360 address book", make a phone call or send a text message. If you send more than 70 messages, it will automatically help you send two messages.
