Why does the short message show that it was sent successfully, but the other party can't receive it?

The mobile phone can't receive SMS for the following reasons:

1, mobile phone arrears

Nowadays, mobile phones are generally used to evaluate credit rating. If the credit rating is high, the amount owed will be larger, which is linked to the credit rating according to whether the payment is timely. Now, if you are in arrears, you will not directly cut off the phone and SMS functions. Therefore, when you can't receive the SMS, please consider whether the operator has sent a SMS to urge you not to pay the phone bill.

2. The storage of the mobile phone is full.

This situation is usually more common in non-smart phones. I believe that the storage of non-smart phones is usually limited. By default, many short messages are stored in the stored mobile phone card, which has a small storage capacity and is usually easy to fill in. At this time, you need to delete some short messages or other contents that occupy memory.

3, the position difference of the signal

In tunnels, tunnels, deep mountains and sparsely populated places, the signal is generally poor, and mobile phones can't receive short messages. Or other places, but the instrument with signal shielding shields the cell phone signal, so it is temporarily unable to receive information.

4. Set the blacklist and block it by software.

Another possibility that the mobile phone can't receive the verification code is that it was intercepted by security software. Just find the software, open and view the intercepted SMS, and delete the corresponding number from the blacklist.

5. The mobile phone network is in poor condition and the signal is poor, so the mobile phone can't receive the signal.

Observe whether the signal is full. If the cell phone signal is weak, you can try to go outside. Try to turn it off and restart, take out the SIM card and change to a mobile phone.
