How to troubleshoot Galaxy A6 2018 that can’t send MMS

Before you start troubleshooting, verify and ensure that MMS feature is enabled on your phone. You can check that through Apps-> Messages-> then tap More or three vertical dots icon located on the upper-right of the screen. A list of menu options will then show up. Scroll to and select Settings-> More Settings-> Multimedia messages. Make sure it’s turned on. If the problem continues with MMS enabled, then you can go ahead and try the following procedures.

First solution: Restart your Galaxy A6 2018

If you’re using cellular data, turn cellular data off shortly and then back on again. That’ll help refresh mobile data functions on your phone. After turning mobile data off and on, restart your Galaxy A6 2018 to dump cache files including corrupted data that might have caused conflict with the messaging tool, particularly MMS functions on your phone. Here’s how to restart or soft reset a Galaxy A6 2018 smartphone:

  1. Press the Power button until the menu appears.
  2. Then tap the option to Power Off.
  3. After 30 seconds, you can press the Power button again until the device restarts.
  4. Or you can do a force restart by simultaneously pressing and holding the Power button and the Volume Down button on the side until the phone restarts.

Let your phone reboot completely then relaunch the messaging app and retry sending and receiving MMS. if the problem persists, then try the next possible solution.

Second solution: Clear cache from the messaging app

Temporary data that are stored as cache in the messaging app can become corrupted due to certain factors and when this happens, there’s a higher chance for the messaging services to go wrong. To rule this out, clear app cache with the following steps:

  1. Go to Settings.
  2. Tap Applications.
  3. Tap Application manager.
  4. Navigate to Downloaded section.
  5. Then tap to select the Messaging app you’re using. Or to clear cache from all apps, tap All instead.
  6. Tap Clear cache.
  7. You can also Clear data if clearing the cache won’t help. Just follow the same steps then select the option to Clear data.

Clearing data however, deletes all your personal data stored within the messaging app including saved files, profiles and other information. Restart your phone then create a test MMS message to send and receive.

Third solution: Wipe cache partition on your Galaxy A6 2018

If clearing the app cache and data doesn’t help, then you can try wiping cache partition on your Galaxy A6 2018 next. This will clear cache files from the system folders including those that are causing conflict on your phone’s messaging functions, particularly MMS. Here’s how it’s done:

  1. Power off your device completely.
  2. Then press and hold the Power and Volume Up buttons simultaneously for a few seconds.
  3. Release the buttons when the Android screen appears and the phone loads in Recovery mode.
  4. Press the Volume Down button several times to scroll to and highlight Wipe Cache Partition from the given options then press the Power button to confirm selection.
  5. Wait until the phone has finished wiping cache from the system partition. You will then see the Reboot system now option highlighted.
  6. Finally, press the Power button to restart your phone.

Allow your device to finish booting up and then launch the messaging app to check and see if MMS sending and receiving functions are now back up and working as intended. If not, then you may have to consider performing resets.

Fourth solution: Reset network settings on your Galaxy A6 2018

To rule network and server settings errors out from the possible triggers, you can try performing a network settings reset to restore the default network configurations on your phone. This allows you to reconfigure necessary options accordingly. This can likely resolve the issue if MMS stopped working after making changes to the network settings or following a new software update installation. Some updates would automatically override network settings, which eventually led to errors. So here’s what you should do then:

  1. Tap Settings.
  2. Scroll to and tap General management.
  3. Tap Reset.
  4. Select Reset network settings from the given options.
  5. If necessary, enter the screen unlock PIN or password to continue.
  6. Then tap Reset settings to confirm action.

Your phone will restart automatically when the reset is finished. Just wait until it’s completely booted up then enable cellular data and Wi-Fi network. See if that fixes the MMS problem on your phone.

Fifth solution: Restore factory default settings on your Galaxy A6 2018

As your last resort, you can do a master reset or factory data reset to wipe everything out from your phone system including complex bugs and malware that caused MMS error to persist. This reset will also delete all saved data and personal information stored on the internal memory. Should you wish to continue, back up your critical data beforehand. Here’s how it works:

  1. Tap Settings.
  2. Go to Cloud and accounts.
  3. Tap Backup and restore.
  4. If you’d prefer, turn Back up my data and Restore options. You can turn it on if you want to back up data before the reset. Otherwise, leave them turned off.
  5. Then go back to Settings.
  6. Tap General management.
  7. Tap Reset.
  8. Select Factory data reset.
  9. Then tap Reset device to continue.
  10. Finally, tap Delete all to confirm action.

Usually, software errors are resolved after a master reset unless they’re attributed to hardware damage. To find out if the issue has been resolved, create a test MMS message then try send and receive it on your phone. If it works, then you’re good. Otherwise, consider other options.

Other options
