Xiaomi's mobile phone can receive short messages, but it can't send them out. What happened?

Hello, there are several reasons why the information cannot be sent out. You might as well know about it, refer to it and see if there is such a thing.

Reason one: the number sent. Whether the number sent is correct, whether there is 86 before the information, etc. Some systems can't recognize these.

Reason 2: Telephone charges. Can the phone bill guarantee the cost of sending messages?

Reason 3: SMS center code. Check whether the SMS center code has been changed.

Reason 4: Some software intercepts SMS operations.

Reason 5: The cell phone signal is not strong enough?

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.

6. If it still can't be solved, please back up the data, enter Restore to clear the cache, user data and all data, and don't restore the system settings after entering the system.
