What should I do if the secondary card of dual-card dual-standby mobile phone can't receive SMS?

You can check whether the mailbox is full first. If it is full, please delete some information. I still can't get it after deleting it. You can change the machine or card to see if it is a hardware factor. After eliminating the above reasons, you can try to test whether it can be received in other places to see if it is the reason for the weak local signal.

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. If it is a verification code, it is suggested to try sending and receiving again in another location to rule out whether it is caused by network reasons. Change other time periods to receive again.

Check whether the mailbox is full, if so, please delete some information; If you still can't get it after deleting it, I suggest you change the machine or card to see if it is caused by hardware; Check whether it is intercepted by mobile phone interception software; Check whether the cell phone signal is normal and try to test whether it can be received elsewhere.
