Why did I resend the text message three times?

This is caused by the feedback error when the server processes your information, so this situation can't happen every time. Another situation is that your local signal is not very good, and the server received your sending request when sending, but the mobile phone repeated the sending instruction because of the bad signal, so you couldn't see it. You can try turning it off and on again. Then try it again, it should be improved, because some mobile phones are really not so good, and even Nokia sometimes makes this mistake, but in general it is still a problem of mobile operators. .
