What's wrong with Apple's mobile phone 6s not receiving SMS?

How to deal with Apple 6S not receiving SMS verification code;

1. When passing through the gateway, abnormal network communication may lead to the loss of short messages or delay in receiving short messages. Please be patient.

2. The mobile phone is not in good condition and the signal is poor. I suggest you try to turn off your phone for about 30 minutes, or take out your mobile phone card and install it on another mobile phone and try again.

3. Please verify whether the mobile phone has turned on the SMS interception system or installed some SMS interception software. It is suggested that the mobile phone with mobile phone card should try again, or open the SMS interception software to check the SMS interception.

4. As a security verification tool for accounts, mobile phones are not used for a long time or by themselves. It is recommended to replace the bound mobile phone. If the mobile phone is not around for the time being, it is recommended that family members (friends) return it. If you are in a hurry, you can ask your family (friends) to forward the verification code before operating.

5. You can't receive SMS when your phone is down or in arrears. If the mobile phone still works, it is recommended to recharge the phone bill before operation.

6. If fast payment is used for payment or contract signing, Alipay has changed its number, but the SMS is still sent to the previous mobile phone. Please contact the bank to modify the mobile phone number reserved by the bank and try again.
