What do you mean you've already sent a text message? Did the other party receive it?

No, it just tells you unilaterally that the short message you sent has been sent to the short message platform of operators (China Mobile, China Unicom and China Telecom) through your mobile phone, and then the short message platform of operators will send the receiving number you entered. But if the other party's number status is abnormal (downtime, arrears, etc.). ), there are still cases where you can't receive it (you can still receive it within 24 hours). If the other party's number is in normal state, it will be easy to receive it. In addition, if the other party's signal is unstable, the SMS platform will send it to the other party many times, which means that if the other party's signal is stable, it will receive multiple messages repeatedly, but only deduct your SMS fee. If the other party's signal has been in an unstable state and can't be received, and the SMS transmission fails after more than 24 hours, the fee deducted before this SMS will be refunded. In this respect, you can manually check the SMS list in the mobile phone list. If-1 is displayed in the expense item, the fee will be refunded. That's about it. I hope I can help you.
