Troubleshooting Galaxy S9 that can’t send MMS

MMS is basically just a text message with some kind of an attachment which means to say that it’s transmission depends on whether your phone gets a good signal from the tower or not. Unlike ordinary texts, MMS needs to be transmitted over mobile data networks that allow internet connectivity since it’s bigger than SMS. Now, with that in mind, here’s what you need to do to fix this problem…

First solution: Force restart your Galaxy S9

If it’s the first time in months that your Galaxy S9 can’t send MMS, then it’s probably just a temporary issue that’s often caused by some minor firmware-related problems. Most of the time, issues like that can be fixed by doing the forced restart procedure or the simulated battery removal. It will refresh your phone’s memory as well as reload all its apps and services. Here’s how  you do it on your Galaxy S9:

  1. Press and hold the Volume Down button and don’t release it yet.
  2. While you’re holding the volume button, press and hold the Power key as well.
  3. Now, keep both keys held down together for 15 seconds or until the Galaxy S9 logo shows.

Once the phone has rebooted, try sending an MMS to your own number to see if it goes through and if you can receive it just fine. If your phone still can’t send MMS, then move on to the next solution.

Second solution: Disable and re-enable mobile data

There are times when services that usually run in the background would crash and may result to this kind of problem. If it is really the case, then you can fix it by simply disabling and enabling the mobile data. If you don’t know yet, you need to have this service enabled for you to be able to send and receive MMS. Here’s how you do it:

  1. Swipe down from the top of the screen using two fingers.
  2. Find the mobile data icon (an icon with arrows pointing up and down) and then tap on it to disable it. If, however, it’s disabled and then you enabled it, then that could be the solution to this problem. The mobile data may have been turned off that’s why you couldn’t send MMS.
  3. Now, enable it back.

After doing this, try to compose an MMS with just an emoji and not a picture or file. Send it to you own number and see if the message goes through. If your Galaxy S9 still can’t send MMS, then move on to the next solution.

Third solution: Reset the texting app you’re using

It is very much possible that this problem is just due to some issues with the texting app you’re using. If you use a third-party application for texting, please uninstall it first and use the native texting app or Messages. After that, try sending an MMS to your own number using Messages and see if it goes through and then proceed to the next procedure below to troubleshoot the problem if you still can’t send MMS. On the other hand, if you’re already using the native app, then here’s what you need to do…

  1. Swipe down from the top of the screen to pull the notification panel down.
  2. Tap the Settings icon on the upper-right corner of the screen.
  3. Find and then tap Apps.
  4. Find Messages among the list and then tap on it.
  5. Touch Storage.
  6. Now, tap Clear cache.
  7. Tap Clear data and then tap OK.

After this, reboot your phone and then try to send an MMS to your own number. If you still can’t send MMS after this, then try the next solution.

Fourth solution: Reset Network Settings

Regardless whether this phone of yours is provided by your service provider together with a plan or you’re using the unlocked version, this procedure will bring back the default values of the APN settings in your phone. If one of the values was changed, that could be the reason why you could no longer transmit MMS. Here’s what you need to do:

  1. Swipe down from the top of the screen to pull the notification panel down.
  2. Tap the Settings icon on the upper-right corner of the screen.
  3. Scroll to and then tap General management.
  4. Tap Reset.
  5. Touch reset network settings.
  6. Tap Reset settings.
  7. If prompted, enter your PIN, Password or Pattern.
  8. Finally, tap Reset.

After this, try sending an MMS to your own number again to see if the problem is fixed. If your Galaxy S9 still can’t send MMS, then it’s time for the factory reset.

Fifth solution: Backup your important files and reset your phone

At this point, a master reset is necessary, although there’s no guarantee that it will fix the problem. It will just rule out the possibility that it’s a firmware problem. Nevertheless, it’s a step you don’t want to miss. However, make sure to create a copy of your important files and data as they will all be deleted especially ones that are stored in your phone’s internal storage. After the backup, make sure to remove both your Google and Samsung accounts so that you won’t be locked out of your device after the reset. Once everything is in order, follow these steps to reset your phone:

  1. Turn off the device.
  2. Press and hold the Volume Up key and the Bixby key, then press and hold the Power key.
  3. When the Galaxy S9 logo shows, release all keys.
  4. Your phone will continue to boot up to the recovery mode. Wait until your phone reaches the black screen with blue and yellow texts on it before you proceed.
  5. Press the Volume down key several times to highlight ‘wipe data / factory reset’.
  6. Press Power button to select.
  7. Press the Volume down key until ‘Yes — delete all user data’ is highlighted.
  8. Press Power button to select and start the master reset.
  9. When the master reset is complete, ‘Reboot system now’ is highlighted.
  10. Press the Power key to restart the device.

After the reset and setup, don’t install anything yet. Instead send an MMS to you number to see if the problem is fixed by the reset. If your phone still can’t send MMS, then either call your service provider or bring the phone to the store. Your provider is the one that knows if it’s account or network issue.
