How to Fix Samsung Galaxy S20, S20+, S20 Ultra Not Sending Texts or SMS

Fix, Galaxy S20 won’t send Texts or SMS not working problem

Check the Error

Error codes or messages are usually key to solving problems. If your messaging app displays an error every time it fails to send texts, be sure to take note of it. Then, do a Google search about the exact message or code and see if there’s any available online solution.

Force Quit Messages app

This is usually recommended to fix minor app bugs. There are two ways to do this.

Method 1: Close an app using Recent Apps key

• On your screen, tap the Recent Apps soft key (the one with three vertical lines on the left of the Home button).
• 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.
• 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

• Open the Settings app.
• Tap Apps.
• Tap the More settings icon (three-dot icon, upper right).
• Tap Show system apps.
• Find and tap the app.
• Tap Force Stop.

Simple Reboot or Forced reboot

Well, I think you already know how to restart your phone. So just restart the device and see whether it solves the issue or not. Restarting a device is always an ultimate solution for any issue. Not only Pixel but this applies to each and every electronic device. I used to tell my mom to restart her device if she faces any issue with her smartphone.

Well if you still need to know how to restart then, here is it: Press your phone’s power button. On the screen, tap Restart.

The other way of the reboot is as follows:

• Press and hold the Volume Down button.
• While holding it down, press and hold the Power key.
• Keep the button held for 10 seconds, it will be restarted automatically.

If this doesn’t work then head to the next method.

Rebooting your device regularly at least once every week can be beneficial. If you tend to forget things, we suggest that you configure your phone to reboot on its own. You can schedule it to do this task by doing these steps:

• Open the Settings app.
• Tap Device Care.
• Tap the 3-dot at the top.
• Select Auto restart.

Verify signal strength

In a lot of network issues, poor or weak signal is to blame. If your Galaxy Note10 is showing No Service all the time recently, be sure to check how the signal bars are showing on your device. Anything lower than 3 bars is not good and can indicate a network issue.

If you are inside a building, try to go out and see if No Service goes away. If you are traveling by car, it’s possible that you may be transiting a dead spot. What you want to do is to move a known well-covered area. If No service remains, there may be an issue with your Galaxy S20/S20+/S20 Ultra. Continue troubleshooting it by following the steps below.

Check if voice calling works

Some carriers may have 4G LTE issues which can also affect other network services. Try checking if texting or voice calling is intermittent or having random issues. If they do have a problem even if there are excellent signal bars, there may be an issue with your network. You must contact your network operator for help.

Delete old conversations

Sending and receiving texts may become problematic if the Messages inbox is full. Try to delete some old conversations that have lots of attachments. They tend to eat up a huge portion of your messaging app’s inbox.

Remove and Reinsert SIM card

I don’t think you need another tutorial to reinstall a sim card in your device. Just remove the sim tray from the device and restart the device and then reinsert it to the device.

• Activate the flight mode.
• Push Sim eject tool into the circular opening on the SIM card tray to remove it.
• Power off the device.
• Remove the Sim card from the Sim tray then place it back in.
• Push the tray back into the slot.
• Boot the device.

Once you’ve removed the SIM card from the device, wait for a few moments before re-inserting it. This has the effect of refreshing the system without the old cellular settings. Once the SIM card is re-inserted and the phone restarted, your network’s configuration should be added automatically.

If you have another phone that can work with your network, you can also try to insert the SIM card to it. This will help you check if there’s an issue with the SIM card itself. If the problem returns when you use the SIM card in the second device, you either have an issue with the SIM or with the network. Try getting a new SIM card to see if it’s the SIM or the network.

Reset Network Settings

• Open Settings from either the Quick Nav menu or the launcher.
• Scroll down and tap on General management.
• Then tap on Reset.
• Finally, tap on Reset network settings.
• Then tap on Reset settings.
• Confirm with your lock screen password when prompted.

Clear app cache

• Open Settings from either the Quick Nav menu or the launcher.
• Tap Apps.
• If you’re looking for a system or default app, tap on More settings at the upper right (three-dot icon).
• Select Show system apps.
• Find and tap the appropriate app.
• Tap Storage.
• Tap the Clear Cache button at the bottom.

Delete app data

• Open Settings from either the Quick Nav menu or the launcher.
• Tap Apps.
• If you’re looking for a system or default app, tap on More settings at the upper right (three-dot icon).
• Select Show system apps.
• Find and tap the appropriate app.
• Tap Storage.
• Tap the Clear Data button.

Troubleshoot apps in Safe Mode

In case you don’t know what is safe mode, in safe mode, the system temporarily disables all third-party applications you installed on your device. By doing this we can figure out which app is occurring the problem. Follow the below step to turn Safe Mode on:

• Turn OFF the device.
• Press and hold your device’s Power button till the model name screen.
• When the SAMSUNG logo appears on the screen, release the Power key.
• Immediately after releasing the Power key, press and hold the Volume down key.
• Continue to hold the Volume down key until the device finishes restarting.
• Safe mode will display in the bottom left corner of the screen.
• Release the Volume down key when you see Safe Mode.

After figuring out the apps which are creating the problem, follow the below steps to uninstall it(if required):

• Open Settings from Launcher.
• Tap on Apps.
• Tap See All Apps.
• Tap an app that you want to uninstall
• Tap Uninstall.
• Tap OK to confirm.

Clear Cache from Recovery Mode

In case you don’t know what is recovery, the first thing the bootloader rings up is recovery. Recovery Mode refers to a special bootable partition, which contains a recovery application installed in it. And you can fix some problems with your phone. Follow the steps to clear cache from recovery mode:

• Turn off your phone.
• Once it is turned off. Press and hold the power/Bixby and volume down button simultaneously until the Android logo pops up.
• When the green Android logo displays, release both buttons.
• The Recovery screen menu will now appear
• Use the Volume button to go to Wipe Cache Partition then press the Power button to confirm the selection.
• Wait until your device wipes out all cache or temporary data from the system partition.
• Press the Power button again to reboot the device.

This clears all the temporary data from the device. And then it works like new.

Factory Reset

From the Settings menu:

• Open the Settings from the launcher.
• Scroll to and tap General management.
• Tap Reset.
• Select Factory data reset.
• Tap Reset to continue.
• Tap Delete All to confirm the action.

From Recovery:

• Turn off your phone.
• Once it is turned off. Press and hold the power/Bixby and volume down button simultaneously until the Android logo pops up.
• When the green Android logo displays, release both buttons.
• The Recovery screen menu will now appear
• Use the Volume Down button until you are highlighting ‘Wipe data/factory reset.’
• Press the Power button to select ‘Wipe data/factory reset.’
• Use Volume Down to highlight Yes.
• Press the Power button to confirm the action to clear your phone data.

Contact your carrier

No Service bug can be caused by an issue from your network operator so you won’t be able to fix it on your end at all. Talk to your carrier and let them check the problem if nothing is fixed after a factory reset.

Visit the Service Centre

Although it’s rare, some cases of overheating issues on Samsung Galaxy devices may have bad hardware as the origin. If a factory reset won’t help in fixing your issue, visit your local Samsung store or Service Center so a qualified Samsung technician can examine the hardware. If needed, they may send it in for repair or replacement.
