The message has been received. I got it.

SMS is the basic principle of "Initiating SMS-SMS Center-SMS Termination".

After the short message arrives at the center, the short message center begins to address and find the number of the receiver. It will send a message to this number, accept the message sent by the mobile phone and send a reply message. He has received it, but if your mobile phone doesn't reply this confirmation message, the SMS center will keep sending the same content on the mobile phone, and he has received the confirmation. So far, if you haven't received it, the default maximum transmission time is 48 hours.

What you said should be that your information center terminal did not confirm and mistakenly thought that you did not receive the message, so he would send the same content. This may be a problem with your mobile phone, or it may be the same. The core problem of users around you, local wireless network or SMS should be network congestion or performance failure. Suggest calling 10086. Around the user, if you are not, then you have such a situation, that is the problem of your mobile phone;
