Red bean telecom card, others can't receive my message. What's the matter?

1. Please check whether the mailbox is full first. If it is full, please delete some information.

2. If it is still not received after deletion, you can change the machine or card to see if it is a hardware factor;

3. 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.

Solution:

1. Please put your mobile phone card in another mobile phone to see if you can send and receive short messages.

2. If you can't receive the short message, please contact the network operator to see if it's the sim card.

3. If you can send and receive short messages, I suggest you plug the card back into your mobile phone and send yourself a short message to see if you can receive it.

Please enter the SMS center and contact your mobile operator to check your SMS center number.

5. If the number is correct, please uninstall your system security software temporarily.
