Why did you only send a message to your friend, but the other party received several messages?

When sending a text message to a friend, only one message was sent, but the other party received several messages. There may be the following reasons:

1. After your friend receives the short message, the system will send back a success status report to the short message center. Due to system reasons, the SMS center will think that the user failed to receive it and send it several times to ensure that the other party can receive it normally. Sending the same message repeatedly (excluding your repeated sending) will only charge you once;

2. SMS can send up to 70 Chinese characters or 160 English letters at a time. You can also send this message if your mobile phone supports editing more than 100 Chinese characters. In this case, your friend will receive multiple messages, and the cost will be calculated according to the number of messages actually received by your friend.
