How to fix Samsung Galaxy S10e that can’t send MMS [troubleshooting guide]

Troubleshooting this kind of issue requires a number of steps. That’s because there’s no single reason for it. Below are the order of steps that you can try to figure out where the problem comes from.

Refresh the device. Before doing any drastic action, it’s not a bad idea to refresh the system. Restarting your Galaxy S10e can be a good simple way to fix the problem. Some network troubles have actually simple causes, such as a temporary bug or error in the software or app. By restarting the device and clearing the RAM, you may be able to address the problem without doing any more drastic steps.

In your case, we recommend that you simulate the effects of a “battery pull” to fully refresh the system. Here’s what to do:

  1. Press and hold the Power + Volume Down buttons for approximately 10 seconds or until the device power cycles. Note: Allow several seconds for the Maintenance Boot Mode screen to appear.
  2. From the Maintenance Boot Mode screen, select Normal Boot. Note: Utilize the volume buttons to cycle through the available options and the lower left button (below the volume buttons) to select. Also, allow up to 90 seconds for the reset to complete.

Take note of error. The next good troubleshooting step for your case is to be aware of whatever error showing on the device. Usually, a device will display an error or show some indicators of the problem. Once you’ve secured the error, do a Google search for it to know the causes. From there, you can then find your own solutions. If the error is unique to your device and no other user posted it online, you can also talk to your network operator.

Confirm mobile data is working. MMS requires cellular data to work. If you’re having trouble with mobile data or cellular data on your S10e, your MMS issue must be tied to it. Try to toggle mobile data on and off and see if that will help. You can also check if you have the correct APN settings. If you’re getting an error when using mobile data, or when there’s incorrect APN settings, you should talk to your carrier about it. Majority of mobile data problems are related to billing or account issue. These are usually beyond your ability to fix so you must let your carrier’s support team to figure it out.

The easiest way to know if mobile data is working is by using an app that requires internet to work like YouTube or Netflix. These streaming apps constantly need internet connection so if you’re having trouble using them, that’s a telltale sign of a mobile data problem.

Check voice calling is working. If mobile data works but voice calling does not, that’s another sign of a possible issue that only your carrier can address. Report the problem to them and your MMS issue will most likely fade away with it.

Toggle Airplane Mode. In some cases, toggling Airplane Mode on and off also helps. An enabled Airplane Mode can sometimes be the reason why mobile data is not working. By default, Airplane Mode turns off cellular connections. If you’ve been travelling lately and you suddenly realize mobile data is not working, it’s probably because you forget to turn Airplane Mode off.

Reset network settings. Clearing the current network settings may also help. This troubleshooting step is usually effective in fixing problems related to cellular or Bluetooth troubles. Here’s how it goes:

  1. From the Home screen, swipe up on an empty spot to open the Apps tray.
  2. Tap General Management.
  3. Tap Reset.
  4. Tap Reset network settings.
  5. Tap Reset settings.
  6. If you have set up a PIN, enter it.
  7. Tap Reset settings. Once complete a confirmation window will appear.

Clear messaging app cache. Another possible point of failure in this case is the messaging app. To troubleshoot it, there are four things that you can try: clear the cache, delete conversation threads, clear the data, or use a different one. The first step is to clear the app’s cache. Here’s how to do it:

  1. Open Settings app.
  2. Tap Apps.
  3. Find and tap the messaging app.
  4. Tap Storage.
  5. Tap Clear Cache button.
  6. Restart the device and check for the problem.

Delete old conversations. If you’re having trouble sending MMS to one contact only, it’s possible that the cause is a buggy conversation thread. Delete the old conversation and create a new one. If MMS sends successfully, this can be the solution you’re looking for.

Clear messaging app data. If nothing has worked so far, the next troubleshooting step involves resetting the messaging app to its default state. This step will erase all messages so be sure to back them up ahead of time. Once you’ve secured your messages, follow these steps to clear the data of the app:

  1. Open Settings app.
  2. Tap Apps.
  3. Find and tap the messaging app.
  4. Tap Storage.
  5. Tap Clear Data button.
  6. Restart the device and check for the problem.

Try another app. Using another app can also be a good way to resolve this issue, especially if you suspect that it’s app related. There are many messaging apps that you can use for this troubleshooting in the Play Store. Make sure to use trusted ones only. Google’s own Android Messages is a good app to try first.

Clear cache partition. Android uses system cache to load apps and services quickly. This cache can sometimes get corrupted resulting to problems. To ensure that your S10 uses fresh cache, don’t forget to clear the cache partition. Here’s how to do that:

  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 Android logo displays, release all keys (‘Installing system update’ will show for about 30 – 60 seconds before showing the Android system recovery menu options).
  4. Press the Volume down key to highlight “wipe cache partition.”
  5. Press the Power key to select.
  6. Press the Volume down key to highlight “yes” and press the Power key to select.
  7. When the wipe cache partition is complete, “Reboot system now” is highlighted.
  8. Press the Power key to restart the device.

Factory reset. Should none of the suggestions above work, wipe the phone and reset it to its defaults. Don’t forget to back your personal data up first to avoid losing them. Once you’ve done that, follow these steps to factory reset your phone:

  1. Back up data on the internal memory. If you have signed into a Google account on the device, you have activated Anti-theft and will need your Google credentials to finish the Master reset.
  2. Turn off the device.
  3. Press and hold the Volume Up key and the Bixby key, then press and hold the Power key.
  4. When the Android logo displays, release all keys (‘Installing system update’ will show for about 30 – 60 seconds before showing the Android system recovery menu options).
  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.

Talk to your carrier. If wiping your phone won’t help or make any difference, that means that either the issue originates deeply in the software (programming issue), or there’s a network problem that we’re not aware of. Let your network operator figure out the cause for you.
