MIUI_V4 10.15 SMS sending failed?

Hello,

1. SMS interface-menu key-settings-advanced settings-set SMS center number. For example, 8613800000000

2. Dial interface-*#*#4636#*#*-Mobile phone information-SMSC input: "SMS center number", 145

For example "8613800000000", 145

3. If you still cannot send text messages, take off the mobile phone card, insert it into another mobile phone, set the SMS center number, and insert the SIM card back into the mobile phone again.

4. Are there any optimization software such as power saving, optimization, assistant, and forced end of tasks installed? It is recommended to close or uninstall it.

5. Try installing third-party SMS software. If Third-party software can send and receive normally, please clear the text message data (method: Settings--Programs--All--Information--Clear data).

Thank you for your support and wish you a happy life!
