What is the problem that a mobile phone receives the same text message many times in a row?

There are many reasons why mobile phones receive the same text message many times, including:

Signal problem of the sender: for the sender, when the mobile phone signal is not good enough to receive the feedback signal from the intermediate terminal, it will be considered that the message was not sent successfully, and most users will choose to resend it, resulting in the same message being sent many times;

Problems in the middle end: when the number of short messages increases sharply on New Year's Day, especially on New Year's Eve, the middle end may get stuck and send the sent information again by mistake, resulting in the receiving end receiving duplicate short messages;

Signal problem at the receiving end: the mobile phone received the short message but did not feedback the result, resulting in repeated reception;

Memory problem at the receiving end: insufficient memory can also lead to the inability to receive short messages, and the mobile phone can't read messages even if it keeps prompting to receive them;

The sender's purpose is not pure: some advertisers or scammers will send a lot of junk information and "bomb".
