// The fourth parameter: sentIntent determines whether the text message is successfully sent. If you do not have a SIM card or the network is interrupted, you can use this intent to determine.
// Note whether the "send" action is successful. In other words
// The Fifth parameter: The deliveryIntent is received when the text message is sent to the recipient. That is, the result after "sending" is emphasized.
// This means that sentIntent and deliveryIntent are activated only when the message "sent successfully" and "received by the recipient. This is equivalent to the delay in Intent execution.
