Mobile phones will automatically repeat several long messages, but not short messages. What happened?

It shouldn't be sending several messages repeatedly, but because the other party's mobile phone doesn't support long messages, it will automatically divide your long messages into several messages to send. If you move, 70 words count as one message, 140 counts as two messages, 2 10 counts as three messages, and so on.
