12306 What the hell is it that the SMS verified by the mobile phone can't receive a reply?

If Samsung's mobile phone can't receive short messages of certain numbers, it is suggested that:

1. If it's an official SMS from an operator, a bank or a group purchase, please try to resend it, check the status of the sim card, and restart your phone later to receive it again.

2. If it is a verification code, it is recommended to change to another location and try to send and receive it again to rule out whether it is caused by network reasons.

3. Change other time periods to receive again.

4. Verify whether the SMS blacklist function is set in the mobile phone. It is recommended to open the phone settings-Call/Message Interception-Message Interception List-Remove All.

5. Check whether the mobile phone has downloaded the latest third-party software (security guards, system management). It may be that the software intercepted the short message, so it is recommended to uninstall it.

6. Try to replace another SIM card.

7. If not, please back up your mobile phone data (phone book, SMS information, multimedia materials, etc.). ) and restore the phone factory settings.

If the problem still exists, it is recommended to bring the purchase invoice, maintenance card and mobile phone to the local Samsung service center for engineers to solve.
