Samsung SMS Not Sending: Troubleshooting Tips for Android Users

Many Samsung users have reported issues with sending SMS messages on their devices. These issues can range from slow message delivery to complete inability to send messages. There are a variety of reasons why Samsung SMS messages may not be sending, including network issues, message center number settings, and iMessage configuration.

One common cause of Samsung SMS issues is network problems. Poor signal strength or network outages can result in messages being delayed or not sent at all. Users can use apps like Open Signal to locate nearby towers and improve their signal strength. Additionally, users should contact their carrier to ensure their account is in good standing and there are no service outages in their area.

Identifying the Issue

If you are experiencing issues with sending SMS messages on your Samsung device, there could be several reasons why. By identifying the cause of the problem, you can take the appropriate steps to resolve it.

Network Related Issues

One of the most common reasons why SMS messages fail to send is due to network-related issues. This could be due to poor network coverage or a network outage. To check if this is the case, look at the signal indicator on your device. If it is weak or non-existent, this could indicate a network issue.

Another possibility is that your network operator is experiencing technical difficulties. You can check if this is the case by contacting your network provider or checking their website for information on network services.

Phone and Software Related Issues

If the problem is not related to the network, there could be an issue with your phone or software. One possibility is a system glitch, which can cause various issues with your device, including problems sending SMS messages.

Exploring Solutions

If you are experiencing issues with Samsung SMS not sending, there are several solutions you can try. These solutions fall into three main categories: Messaging App Solutions, Service Provider and Carrier Solutions, and Phone Settings and Reset Options.

Messaging App Solutions

One of the first things to check is the messaging app you are using. Make sure it is the default messaging app and that it is compatible with the current software version. If you are not sure, try changing the default messaging app to see if that resolves the issue. You can also try clearing the cache for the messaging app or updating the app to the latest version.

Service Provider and Carrier Solutions

Another possible cause of SMS not sending is a network issue. Check for possible causes of SMS and MMS message errors, such as low signal strength or network congestion. You can use an app like Open Signal to find nearby towers and move closer to get a better signal. If you stopped receiving messages after a software update, functionality may also be restored by changing the default messaging app. You can also try resetting the network settings or the APN settings.

Phone Settings and Reset Options

If none of the above solutions work, you can try resetting the phone settings or performing a factory reset. Before doing so, make sure to backup your data as a factory reset will erase all data on the phone. You can also try putting the phone in airplane mode for a few seconds, and then turning it off to reset the network connection.

Dealing with Specific Cases

If you are still experiencing issues with Samsung SMS not sending, there may be specific cases that are causing the problem. This section will cover some of the most common cases and provide possible solutions.

Issues with iMessage

If you recently switched from an iPhone to a Samsung device, you may be experiencing issues with sending and receiving SMS messages. This is because your phone number may still be registered with Apple's iMessage service. To fix this, you will need to unregister your phone number from iMessage.

To unregister your phone number from iMessage, follow these steps:

  1. Go to the Apple website and navigate to the "Deregister iMessage" page.
  2. Enter your phone number in the "Phone Number" field.
  3. Click on "Send Code" to receive a verification code via SMS.
  4. Enter the verification code on the website and click on "Submit".
  5. Your phone number is now unregistered from iMessage.

Issues with Third-Party Apps

If you are using a third-party messaging app on your Samsung device, it may be causing issues with SMS messages. Try switching to the default messaging app and see if that solves the problem.

To switch to the default messaging app, follow these steps:

  1. Go to "Settings" on your Samsung device.
  2. Navigate to "Apps" and select the messaging app you want to disable.
  3. Tap on "Disable" to disable the app.
  4. Go back to the home screen and open the default messaging app.

Issues with SIM Card

If your SIM card is damaged or not inserted properly, it can cause issues with sending and receiving SMS messages. Try removing and reinserting the SIM card to see if that solves the problem.

To remove and reinsert the SIM card, follow these steps:

  1. Turn off your Samsung device.
  2. Locate the SIM card slot on your device (usually located on the side or back).
  3. Use the SIM ejector tool (or a paperclip) to eject the SIM card.
  4. Inspect the SIM card for any damage or debris.
  5. Reinsert the SIM card into the slot and turn on your device.

If none of these solutions work, you may want to consult a troubleshooting guide or contact Samsung support for further assistance.
