About S4 sending and receiving short messages?

According to the situation you described, since the mobile phone can send messages normally, there is no problem with the model of the mobile phone. I suggest you:

1. To eliminate the problem of SIM card, I suggest you change to another SIM card to see if there is any phenomenon that you can't receive information on time. If you can receive it, there may be something wrong with the original SIM card. I suggest you change your card in the business hall of the network operator.

2. If you still can't receive it normally, I suggest you check whether the mobile phone has downloaded third-party security software recently. It may be because of the compatibility problem between the software and the mobile phone that the mobile phone can't receive normally. It is recommended that you uninstall the software and check whether it is back to normal (Settings-More-Application Manager-Select Download-Uninstall).

3. If it doesn't return to normal, I suggest you back up your mobile phone data (phone book, SMS, multimedia files, etc.). ) and try to restore the factory settings (Settings-Account-Reset-Restore Factory Settings);

4. If the problem still exists, it is suggested that you take the three-guarantee certificate of your mobile phone to the nearest Samsung service center for testing. Please visit the specific service center address:
