How To Fix the LG V40 ThinQ Can’t Send MMS Issue

Before performing any of the recommended troubleshooting steps for this problem on this phone it’s best to make sure that it is running on the latest software version first. If an update is available then I suggest that you download and install it first. Once the software has been updated then proceed with the steps listed below.

Your phone must first satisfy two conditions in order for it to successfully send and receive an MMS. First, it must have an active mobile data subscription and that it is getting a strong mobile data signal, preferably LTE. Second, it should have the correct APN settings. Each carrier has their own different APN setting. You should compare your phone APN settings to what your carrier is using and make the necessary changes if needed. You can get your carrier APN settings from their website or you can also get it from their customer service hotline.


You can access the APN of your phone by the following steps:

  • From the Home screen, Settings.
  • Tap the ‘Networks’ tab.
  • Tap More > Mobile networks > Access Point Names.

If your phone meets both conditions listed above and the issue still persists then you should proceed with the additional troubleshooting steps listed below.

Perform a soft reset

This action will refresh the phone software which will usually issues caused by a minor software glitch. To perform this procedure just press and hold the Power button and Volume Down until the device powers off, approximately 8 seconds, then release. Once this is done try to send and MMS.

Clear the cache and data of the messaging app

There are instances when corrupt data within the text messaging app can cause this problem. To eliminate this possibility you will need to clear the cache and data of the text messaging app.

  • From the Home screen tap Settings.
  • Tap the ‘General’ tab > Apps & notifications.
  • Tap App info.
  • Tap the filter to select  All
  • Tap the Messaging app, then Storage.
  • Tap Clear cache or Clear Data then YES

Check if the issue still occurs.

Check if the issue occurs in Safe Mode

There are cases when an app you downloaded will cause issues on the phone when they are installed. To check if an app you downloaded is causing the problem you will have to start the phone in Safe Mode as only the pre-installed apps are allowed to run in this mode.

  • With the screen on, press and hold the Power key.
  • In the options menu that displays, press and hold Power off.
  • When prompted to restart in Safe Mode, tap OK.
  • When the device restarts, it displays Safe mode at the bottom of the screen.

In case the issue does not occur in this mode then it is most likely caused by an app you installed. Find out what app this is and uninstall it.

Finding the app that’s causing this problem is going to be a trial and error method. Start the phone normally then uninstall an app. Check if the issue still occurs. Repeat this step until the issue no longer occurs after uninstalling an app. That app is most likely what’s causing the problem.

Wipe the cache partition of the phone

There are cases when the cached data stored in the dedicated partition of the phone can become corrupted. When this happens this this will usually cause certain issues to occur on the phone. To eliminate the possibility that this is what’s causing the problem you will have to wipe the cache partition of the phone from the recovery mode.

  • From the Home screen, tap Settings.
  • Tap the ‘General’ tab.
  • Tap Storage > Internal storage.
  • Wait for menu options to finish calculating.
  • Tap Free up space.
  • Tap Temporary files & raw files.
  • Select the following options: Cached data, Clip tray temporary files, Raw files from camera.
  • Tap Delete > DELETE

Check if the issue still occurs.

Perform a factory reset

In case the above steps fails to fix the LG  V40 ThinQ can’t send MMS issue then your last option is to do a factory reset. Make sure to backup your phone data before doing the reset as this will be deleted in the process.

  • Turn off the device.
  • Press and hold the Power and Volume down buttons.
  • When the LG logo appears, quickly release and then re-hold the Power button while continuing to hold the Volume down button.
  • When the ‘Delete all user data (including LG and carrier apps) and reset all settings’ message appears, use the Volume down button to highlight Yes.

Once the reset is complete setup your phone again making sure that the APN setting is correct then check if the issue still occurs.
