The reason why the text message cannot be sent.

1.The other party has set up a firewall, and your text message has been successfully sent, but the other person's mobile phone refuses to receive it. The billing is still the same, and the delivery is successful, but the receipt received is a failure.

2.The other party's mobile phone is turned off, or there is no signal, and the other party does not receive the text message you sent, but if the time exceeds the validity period of the text message set by the other party, it will also prompt that the delivery of the spring model is successful, but the receipt received is a failure.

3.Communication problems, that is, they have nothing to do with the mobile phones of both parties, may be caused by a bad signal or a communication error.

Secondly, as long as your mobile phone shows that the sending is successful, it will be billed. It doesn't matter if the other party receives it or not. That is, if you send an SMS to a down number, you will be charged as long as it is successfully sent.

Also, mobile phone SMS is not like mobile phone communication, it is not a long-distance and roaming slowly, no matter how much information is sent to **, the fee charged is the same, so compared to calling, SMS is a more cost-effective way of communication.

If the signal in your location is normal and the number status is normal, we recommend that you check the location as follows:

1. Check whether one number is given, or all numbers cannot be sent;

2. Check whether the mobile phone has blocked the function of sending and receiving SMS;

3. Check whether the SMS mailbox is full, if so, please delete part of the information;

4. Check whether the SMS center number is set correctly, for example, the SMS center number of China Unicom Beijing is: +8613010112500.
