How to Fix Failed Text Messages on a Xiaomi Phone: A Complete Guide

Experiencing failed text messages on your Xiaomi device can disrupt communication and cause frustration. This guide provides a comprehensive set of troubleshooting steps to resolve this issue and restore your messaging functionality.

1. Check Network Connectivity

A weak or unstable network connection can prevent text messages from sending or receiving. Verifying your network status is a fundamental troubleshooting step.

1. Ensure your phone has a strong signal.
2. Try toggling airplane mode on and off.
3. If using Wi-Fi calling, verify a stable Wi-Fi connection.
4. If using mobile data, check your data plan and signal strength.

2. Restart Your Xiaomi Phone

A simple restart can often resolve minor software glitches that may be interfering with messaging. Refreshing the operating system can fix temporary errors.

1. Press and hold the power button.
2. Select “Restart” from the power menu.
3. Wait for your phone to reboot.

3. Verify the Recipient’s Number

An incorrect or improperly formatted phone number will result in failed messages. Double-checking the number ensures accuracy.

1. Confirm the recipient’s phone number is correct.
2. Ensure the number is in the correct format (including country code if necessary).
3. Try manually entering the number instead of selecting it from contacts.

4. Clear the Messaging App Cache and Data

Corrupted cache or data within the messaging app can cause sending failures. Clearing these files can restore app functionality.

1. Open the Settings app.
2. Tap on Apps or Manage apps.
3. Find and select your messaging app (e.g., Messages, Mi Messages).
4. Tap on Storage.
5. Tap on Clear cache and then Clear data.
6. Restart your phone.

5. Check the SIM Card

A loose or damaged SIM card can disrupt network communication and message delivery. Ensuring proper SIM card installation is crucial.

1. Power off your phone.
2. Remove and reinsert the SIM card.
3. Ensure the SIM card is properly seated.
4. If possible, try using a different SIM card to test.

6. Update the Messaging App

Outdated messaging app versions may contain bugs that cause sending failures. Updating the app ensures you have the latest fixes.

1. Open the Google Play Store or Xiaomi GetApps.
2. Search for your messaging app.
3. Tap Update if an update is available.

7. Update MIUI/Android

Outdated system software can lead to compatibility issues and message failures. Keeping your system updated is vital for stability.

1. Open the Settings app.
2. Tap on About phone.
3. Tap on System update.
4. Download and install any available updates.

8. Check SMS Center Number

An incorrect SMS center number will prevent messages from being sent. Verifying and correcting this number is essential.

1. Open the phone dialer.
2. Dial *#*#4636#*#*. (This code may vary depending on MIUI version. If it does not work, check your carriers website for the proper code.)
3. Select Phone information.
4. Scroll down to SMSC.
5. Verify the SMSC number with your mobile carrier.
6. Enter the correct SMSC number and tap Update.

9. Check for Carrier Outages

Sometimes, network outages or maintenance can affect messaging services. Checking with your carrier can rule out network issues.

1. Contact your mobile carrier’s customer support.
2. Check your carrier’s website or social media for outage announcements.
3. Ask if there are any known issues affecting SMS services in your area.

10. Check for Third-Party App Interference

Some third-party apps, especially those related to messaging or security, can conflict with the default messaging app. Disabling or uninstalling these apps can resolve the issue.

1. Boot your phone into Safe Mode.
2. Check for failed messages in Safe Mode.
3. If messages send successfully in Safe Mode, a third-party app is likely the culprit.
4. Uninstall recently installed or suspicious apps.

11. Reset Network Settings

Resetting network settings can resolve issues related to network configurations that may be affecting messaging. This is a common solution to network related issues.

1. Open the Settings app.
