Why do old people's mobile phones receive short messages intermittently?

The reasons why mobile phones of the elderly intermittently accept short messages are as follows:

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 your sim card, and restart your mobile phone to receive it again later.

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.

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 message, so I suggest you try 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.

8. Check whether the SMS center number is correct.
