If the message received by the old machine is pulled out, is the message still there?

Please put the card down, put it on another mobile phone, and try to receive SMS. No, it means there is nothing wrong with the card. If you can't get it, it's the card. This situation can be handled through the manual service desk. Now you can receive ordinary short messages on your mobile phone. If you can't receive it, it should be that there is something wrong with your mobile phone software. Just brush the software in a repair shop.
