How to fix Galaxy S10 5G won’t send MMS | troubleshooting MMS not working

If your Galaxy S10 5G won’t send MMS and you can’t figure out what’s causing it, follow the troubleshooting steps below.

S10 5G won’t send MMS fix #1: Enable mobile data

In order for MMS to work, a device must have a working cellular data connection. So, the very first thing that you want to do in this case is to ensure that mobile data is enabled. Mobile data is enabled by default but it won’t hurt if you can quickly pull down the notification bar and tap on Mobile data. If it’s your first time to send and receive MMS on this device, you want to make sure that this important step is done. However, if MMS was previously working but now stopped for some reason, there’s probably an account or device issue causing it. You should continue with the troubleshooting steps below.

Keep in mind that MMS won’t work with wifi. If you don’t have an active mobile data subscription, talk to your carrier on how to enable it.

S10 5G won’t send MMS fix #2: Check for errors

Developers include errors when  building their products to aid in troubleshooting. If there’s any error that shows up when sending of MMS fails, you should take note of that. Then, be sure to do a quick Google search about the error to see if there’s any online solution that you can try. Most MMS errors are carrier-specific. If you’re lucky and the error you’re getting is a known one, there may be a handy solution that you can try.

S10 5G won’t send MMS fix #3: Force quit messaging app

If your S10 5G still won’t send MMS at this point, there may be an issue with the messaging app. Try to force quit your messaging app and see if that will fix the problem. Below are the two ways to force quit an app:

Method 1: Close an app using Recent Apps key

  1. On your screen, tap the Recent Apps soft key (the one with three vertical lines on the left of the Home button).
  2. Once the Recent Apps screen is shown, swipe left or right to look for the app. It should be here if you managed to run it previously.
  3. Then, swipe up on the app to close it. This should force close it. If it’s not there, simply tap the Close All app to also restart all apps.

Method 2: Close an app using App Info menu

Another way to force close an app is by going within the app’s settings itself. It’s a longer way compared to the first method above but it’s equally effective. You want to use this method if you plan on doing other troubleshooting for the said app like clearing its cache or data. Here’s how it’s done:

  1. Open Settings app.
  2. Tap Apps.
  3. Tap the More settings icon (three-dot icon, upper right).
  4. Tap Show system apps.
  5. Find and tap the app.
  6. Tap Force Stop.

S10 5G won’t send MMS fix #4: Perform soft reset

If you know for a fact that cellular or mobile data works, then the next step that you want to do is to restart the phone. While restarting your S10 normally should be fine, it’s better if you can simulate the effects of a “battery pull,” also known as soft reset. This clears the RAM so if a temporary bug is tied to the current Android OS session, this might help. In older Galaxy S devices, this type of restart is easily done by removing the battery. Since the Galaxy S10 does not have a removable battery pack, you want to do a combination of hardware buttons to restart it. Here’s how to do that:

  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.

S10 5G won’t send MMS fix #5: Refresh system cache

If your Galaxy S10 5G still won’t send MMS, the next thing that you should do is to ensure that the system cache is refreshed. Android uses a special cache called system cache to load apps quickly. Sometimes, updates or system-wide changes may make this cache outdated or corrupted. This can result to a variety of  problems. To ensure that you have a refreshed system cache, make sure to do the steps below:

  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.

S10 5G won’t send MMS fix #6: Keep the software and apps updated

An outdated Android OS can also cause problems with other apps. Make sure that you install any available software update there is. To check for Android or system update:

  1. Open Settings app.
  2. Tap Software update.
  3. Tap Download and install.
  4. Wait for the device to check for updates.
  5. Install the update. If there’s no new update, your phone should tell you so.

Just as important is updating apps. Some apps may affect other apps if they’re not working properly, or if they’re outdated. You can manually check for new updates in Play Store app. Here’s how:

  1. Open Play Store app.
  2. Tap More settings icon (at the upper left).
  3. Tap My apps & games.
  4. Tap Update all button.

  1. From the Home screen, swipe up on an empty spot to open the Apps tray.
  2. Tap General Management > Reset > Reset network settings.
  3. Tap Reset settings.
  4. If you have set up a PIN, enter it.

S10 5G won’t send MMS fix #8: Check for bad third party app

Sometimes, a bad or poorly coded app may prevent MMS from working on Android. To check if that’s the case, try to restart the phone to safe mode then send an MMS. If it works fine, you can bet a bad app is behind the trouble. Here’s how to restart your device to Safe Mode:

  1. Press and hold the Power button until the Power off window appears then release.
  2. Touch and hold Power off until the Safe mode prompt appears then release.
  3. To confirm, tap Safe mode.
  4. The process may take up to 30 seconds to complete.
  5. Upon reboot, “Safe mode” appears in the lower-left of the home screen.

Don’t forget: safe mode blocks third party apps but it won’t tell you which of them is the real cause. If you think that there’s a rogue third party app in the system, you must identify it. Here’s what you need to do exactly:

  1. Boot to safe mode.
  2. Check for the problem.
  3. Once you’ve confirmed that a third party app is to blame, you can start uninstalling apps individually. We suggest that you begin with the most recent ones you added.
  4. After you uninstall an app, restart the phone to normal mode and check for the problem.
  5. If your S10 5G is still problematic, repeat steps 1-4.

S10 5G won’t send MMS fix #9: Clear messaging app cache

  2. Tap Apps.
  3. Find and tap the messaging app.
  4. Tap Storage.
  5. Tap Clear Cache button.

S10 5G won’t send MMS fix #11: Reset messaging app

Should nothing happen after clearing an app’s cache, the next good thing that you can do is to clear the app’s data. Unlike the previous procedure, this one might delete important information or data within the app. For example, if you’re trying to address an issue with a messaging app, clearing its data will delete all your messages.
