REDMI Note 9 Pro: How to Fix SMS Sending Issues

Initial Troubleshooting Steps

• 💡 Restart your phone by holding the power button and tapping reboot; this can resolve temporary glitches.
• 🔍 Check your SIM card and network range to ensure you have service, as this is essential for sending SMS.
• 💰 Verify that your carrier services are paid and active to rule out carrier-related issues.

Advanced SMS Settings and App Fixes

• 🎯 Access SMSC (SMS center number) settings by opening the dialer, calling a number, then navigating to Messages > Settings > Advanced.
• ⚙️ Force stop the Messages app via Settings > Apps > Manage apps > Messages to fix temporary application issues.
• 🧹 If force stopping doesn't work, clear all data for the Messages app, but be aware this will delete your SMS conversations.

SIM Card and Network Troubleshooting

• ☁️ Back up important SMS conversations before clearing app data, using tools like Mi Mover or cloud export.
• 📱 Test your SIM card in another phone to determine if the issue lies with the SIM card itself.
• 📶 Reset your phone's network settings by going to Connections and sharing > Reset Wi-Fi, Bluetooth, and mobile networks.

Final Steps and Carrier Contact

• 📞 If the problem persists after trying all previous steps, contact your carrier for further assistance.
• 🔄 As a last resort, consider performing a factory reset on your REDMI Note 9 Pro.
