Why can't Xiaomi 2S send short messages, and it always fails to send them?

1, open the SMS settings.

2. Find the information center in SMS settings.

When you open it, you will see the number of the information center. If it's not a string of numbers of +86, that's one of the reasons why you failed to send a text message.

4. The key step is to enter +86 13800***500 in the number field of the information center, and click OK.

5. Then click resend on the message that failed to send.

6. After modifying the correct information center number, you can send short messages immediately.

7. If you don't understand the operation, you can directly dial 10086 to check the corresponding information center number.

8. If the above operation still doesn't work, it may be your network. You can't send text messages if you owe money. Pay the phone bill and then try restarting the phone.
