How To Fix The LG G8S ThinQ Can’t Send Text Messages Issue

You should make sure that your phone is running on the latest software version before doing the recommended troubleshooting steps listed below. If an update is available then I suggest that you download and install it first. This will minimize the possibility of the problem being caused by an outdated software version.

Verify that your area has a good network signal

If you are in an area that does not have any network signal then you won’t be able to send or receive a text message. To verify if this is a coverage related issue you can check if other devices under the same network are also having the same problem in your immediate vicinity. 

Perform a soft reset

Your device will usually store temporary data to help improve its performance. There are times when this data  can get corrupted which in turn can cause issues to occur on the phone. If this is what’s causing the problem you will need to refresh your phone software. This can be done by restarting the phone which should eliminate any corrupt temporary data in the device. This step will also reset the phone connection to the network which is needed in this case.

  • Press and hold the Power and Volume down key for up to 45 seconds.
  • Wait as the device restarts.

Check if the LG G8S ThinQ can’t send text messages issue still occurs.

Check your SIM card

Sometimes the problem is caused by an issue with the phone SIM card. If this is a SIM card related problem then this can be fixed by turning off the phone and removing the SIM card. Wait for a few minutes before reinserting the SIM card back then turn on the phone. Check if the issue still occurs.

You should also try using a different SIM card in your phone to eliminate the possibility of the problem being caused by a defective SIM card.

Clear the cache and data of the messaging app

Sometimes the data stored in the messaging app can get corrupted and can cause messaging problems. To make sure that this isn’t what’s causing the problem you will have to clear the cache and data of the messaging app.

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

Check if the LG G8S ThinQ can’t send text messages issue still occurs.

Check if the problem occurs in Safe Mode

Sometimes an app you downloaded can cause this problem. To check if this is what’s 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.
  • After your device restarts, it displays Safe mode at the bottom of the screen.

If you are able to send and receive a text message in this mode then the problem could be  caused by an app you downloaded. Find out what app this is and uninstall it.

Reset the network settings

There are instances when the problem is caused by a wrong network settings on your phone. To eliminate this possibility you should reset your phone network setting.

When you reset your phone network settings the following will apply:

  • Stored Wi-Fi networks will be deleted.
  • Stored tethered connections will be deleted.
  • Paired Bluetooth devices will be deleted.
  • Background data sync settings will be turned on.
  • Data restrictive settings in applications that were manually turned on/off by the customer will be reset to the default setting.
  • Network selection mode will be set to automatic.
  • Preferred mobile network type will be set to best.

You can do the reset by following the steps listed below:

  • From any home screen, swipe left to locate and tap Settings.
  • Select the General tab or scroll to and tap Reset.
  • Tap Network settings reset > RESET SETTINGS > Reset Settings.
  • A ‘Network settings have been reset’ message briefly flashes to indicate the reset is complete.

Check if the LG G8S ThinQ can’t send text messages issue still occurs.

Wipe the cache partition

Your phone will store temporary data in a dedicated partition in its storage space which helps the device run apps smoothly. If this data gets corrupted then issues can occur on the device. To make sure that this is not what’s causing the problem you will have to clear the cache partition of the phone.

  • 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

One last troubleshooting step you can perform if the phone is still unable to send a text message is a factory reset. Take note that this will erase your phone data so it’s best to backup the phone data before proceeding.

  • Back up data on the internal memory before performing a factory reset.
  • From the Home screen, Settings.
  • Tap the ‘General’ tab.
  • Tap Restart & reset.
  • Tap Factory data reset.
  • If desired, tap the Erase SD card checkbox.
  • Tap RESET PHONE – Delete all – RESET

You can also perform the factory reset using the hardware keys.

  • Backup all data on the internal memory before performing a master reset.
  • 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.
  • Press the Power button to reset the device

If the issue still occurs after the reset you should contact your service provider regarding this issue.
