My girlfriend has been receiving repeated messages from me these two days. I sent one message, but she received five identical messages, which made her very confused.

When the mobile phone receives the short message, it will reply a response message to the short message center, informing the short message center to delete the short message from the sending library. If the short message center does not receive the response message, it will think that the short message has failed to be sent, and there will be repeated sending! Your mobile phone will receive the same short message repeatedly, and the number of acceptances will be set by the short message center.

As for why the SMS center didn't receive your reply, the problem may lie in the following aspects:

1. There is something wrong with your mobile phone. You can't send a reply message to the SMS center normally after receiving the SMS.

2. There is a problem in your area, and the signal is not good, resulting in the message sent by the mobile phone not being sent to the SMS center.

3. After the short message center handles the fault and receives the response message, the short message is not deleted from the sending library.

The solution can refer to the following steps:

1, change the mobile phone to test whether there is still the problem of receiving SMS repeatedly.

2. Change the area and test in the areas with good signal and poor signal respectively. If it is a signal coverage problem, it is recommended to complain to the operator.

3. If the above two tests are not normal, it is estimated that it is a data configuration problem of the operator, and the complaint is handled.
