Common Causes

The typical way of resolving issues in mobile devices is to start by identifying the underlying cause. Outlined below are common causes of messaging problems in Xiaomi devices:

• Outdated firmware or messaging app
• Connectivity problems like no mobile data, Wi-Fi disconnects
• Issues with phone memory being overloaded
• Cellular network outages in your area
• Glitches following a device update or restore
• Blocked ports causing messaging interruptions
• Bugs in the Redmi 12 hardware or software

Troubleshooting Procedures

Troubleshooting messaging issues in mobile devices typically involves checking the basics including the SIM card and SMSC settings. Performing system restarts and resets are also deemed necessary when ruling out software-related causes.

Outlined below are useful methods that you can try to fix the problem on your end.

Step 1: Update Firmware and Apps

Outdated firmware is a prime suspect for messaging failures on the Redmi 12. Important bug fixes and compatibility changes in system updates often resolve sending issues.

To update software on Redmi 12, follow these steps:

1. Go to Settings > About phone > MIUI version.
2. If a new software update is available, tap Download and install.
3. Follow the on-screen instructions to download and install the latest firmware update for your region and carrier.

Make sure your phone has sufficient storage space and battery life to finish updating.

To update apps on Redmi 12, follow these steps:

1. Open the Google Play Store app.
2. Tap the Menu button (three horizontal lines) in the top left corner.
3. Select My apps & games.
4. Tap Update next to the apps you want to update.
5. You can also tap Update all to update all apps.

Keeping your Redmi 12 firmware up-to-date will ensure maximum messaging stability and fix bugs that may block sending.

Step 2: Verify Cellular and Wi-Fi Connectivity

Lack of mobile data or Wi-Fi connectivity when trying to send texts is an obvious culprit for messaging failures. Checking that you have an active connection is therefore imperative.

Here’s what you should do then:

1. Go to Settings > Connections > Wi-Fi and enable Wi-Fi if disabled
2. Check that you have sufficient cellular data available, if not on Wi-Fi
3. Try manually switching between 3G and 4G in network settings
4. Enable mobile data if mistakenly disabled under Settings > Network & internet > Mobile network. If disabled, toggle the Mobile data switch to the On position.

Confirm that your Redmi 12 has an active, stable internet connection when trying to send messages.

Step 3: Check for Insufficient Storage

If your Redmi 12 has critically low internal storage available, it can interfere with the system’s ability to send SMS text messages reliably.

To check the available storage on Redmi 12, you can follow these steps:

1. Open the Settings app.
2. Tap on Storage.
3. This will show you the total storage space on your phone, as well as the amount of space that is currently being used.
4. You can also see a breakdown of how the storage is being used, by apps, media, and other files.

To see more detailed information about how your storage is being used, you can tap on the More button. This will show you a list of all the apps and files that are taking up space on your phone.

If you are running low on storage space, you can try deleting unused apps, photos, or videos. You can also move some of your files to an external storage device, such as a microSD card.

Freeing up storage if your phone memory is nearly full may allow messages to send correctly again.

Step 4: Investigate Network Outages

Cellular network outages in your area can sometimes temporarily disrupt sending texts, though your Redmi 12 may still be able to receive them. If the problem suddenly occurs without altering your phone’s settings, check for known issues.

Here’s how:

1. Search online for your carrier’s network status page
2. Check if others are reporting messaging problems on social media
3. Try sending test texts to different networks like Verizon, AT&T
4. Wait a short time and retry as network issues are often resolved quickly

Rare carrier outages are usually restored relatively quickly, resolving messaging problems.

Step 5: Restore Redmi 12 to Factory Settings (optional)

If your issues began after a major firmware update or restore, resetting your device can wipe residual bugs or glitches.

Should you wish to proceed with a factory reset on your Redmi 12, backup important data then proceed with these steps:

1. Go to Settings > About phone > Additional settings > Backup & reset.
2. Tap Erase all data (factory reset).
3. Enter your PIN or password if prompted.
4. Tap Erase all data again to confirm.

Factory resetting your Redmi 12 will wipe any problematic settings that could be blocking sent texts.

After the factory reset, your phone will be restored to its original settings. By then, you can set up your device as new.

Step 6: Unblock Ports Used for Messaging

Your cellular provider may block certain connection ports used for sending messages by default. You may need to request they unblock ports.

Contact your carrier and do the following:

1. Ask to enable ports 80, 443, 5222 and 5228 for your account
2. Inform them you are unable to reliably send text messages
3. Request they remove blocks on the ports required for messaging
4. Test sending texts again once they confirm ports are opened

Unblocking the necessary network ports can resolve issues of texts getting stuck.

Step 7: Update Your SIM Card

In rare cases, an old or damaged SIM card may be the reason your Redmi 12 can’t send messages reliably. In this case, replacement may be needed.

So here’s what you should consider doing then:

1. Testing the SIM card in another unlocked device if available
2. Purchasing a new SIM card from your carrier
3. Activating the new SIM card in your Xiaomi account
4. Sending test texts to confirm the new card works in your device

If messaging problems disappear with a new SIM card, your original was likely defective.

Step 8: Perform a Repair Install of MIUI

For persistent issues, reinstalling the MIUI firmware using Xiaomi’s repair tool can refresh core system components.

MIUI firmware reinstallation is the process of flashing a new MIUI firmware onto your Redmi 12. This can be done for a variety of reasons, such as fixing a software problem, updating to a newer version of MIUI, or rooting your phone.

There are two ways to reinstall MIUI firmware on Redmi 12:
