Why does my mobile phone send a short message to the other party, but the other party receives N identical short messages repeatedly, and I have to pay for each one?

The first is network delay. That is, when a message was sent in the past, it was forwarded to the other party's mobile phone through the network server used by the other party, but the other party did not receive it because of the signal or other problems, so the server would repeatedly send it after a certain period of time (such as one minute) until the other party received it.

The second is your network delay, or mobile phone failure. In other words, after you actually click Send, your signal is not actually connected to another server. So your network will automatically default to sending failure, so it will repeat sending again. Until the other server receives it, and at this time, it is very willing to generate fees.

Third, it is the problem of mobile phones. A friend once had a broken cell phone, which was A 1200 of a motorcycle. A few months ago, he received several short messages until the mailbox was full. The date and content of the message are uncertain. Later, he went to the maintenance center to get better. But this should have nothing to do with your mobile phone bill, so it is unlikely.

I suggest you go to the website of your agent (Unicom or Mobile) first, and check the bill list to make sure that the shortage of your mobile phone bill is really caused by these repeated SMS charges. Then call the agent's customer service, complain, inquire and ask for a reply. Then go to the warranty point and ask them to try to refresh the system for your mobile phone (at home if you can). If it's not the agent's problem or the mobile phone system, then I suggest you repair your mobile phone!
