Imessage first shows that the shopping basket has been delivered, and then comes back to see if it has been sent by SMS. Why?

Blue indicates that imessage is on the opposite side, and green indicates ordinary SMS. Because you have turned on the SMS sending button, if SMS is not successfully sent in imessage, it will be sent by conference SMS, and the information fee is 1 cent each time. Imessage is free, and only ios has imessage function for ios. You can turn off the Send SMS button in the SMS page, which won't happen.
