Xiaomi's text message keeps showing that it is being sent. What if I can't send it out?

Open Settings ~ Application ~ Information ~ Clear Data to see if it is normal. If it still doesn't work, please put your mobile phone card into other mobile phones to see if you can send and receive short messages normally. If you can't send and receive SMS normally, please contact the network operator to see if it's a sim card problem. 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. If the number is correct, please temporarily uninstall your system security software. If it still can't be solved, please back up the data, enter the recovery to clear the cache, user data and all data, and don't restore the system settings after entering the system.

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

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

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

4. Some software will intercept short messages.

5. Whether the cell phone signal is not strong enough.
