On sending and receiving long short messages

When you send a long message, the whole message will be sent to the information center at the same time. The information center divides your message into multiple parts, 70 words as a message, and sends it to the other party at the same time. So when the other party accepts your message, sometimes it will be accepted part by part, forming a complete message in the other party's mobile phone. Similarly, if you send a long message, the operator will divide the number of words you say you want to send by 70 and then charge you the information fee by 1. Cancel sending during sending, and the other party will not receive the message.
