How many characters should a text message break?

Generally, there are no normal ones, but spaces are used instead. Add a space after the first sentence and then type the second sentence. If the second sentence is long, it will automatically wrap. The key is that the person who receives the text message, the model and font size of the mobile phone are different, and the difference between what you receive and what you call is less.

A short message sent by the service provider is 70 words, including line breaks and spaces.

If the service provider is different, the message will be sent to the other machine in different ways.
