In a previous guide, we discussed solutions on how to fix a Samsung Galaxy S21 that cannot make calls. However, we have noticed a significant number of users reporting that they are also unable to receive calls. This has led us to create this comprehensive guide to help you resolve this issue.

There are a few possible reasons why your Galaxy S21 is not receiving calls. The common culprits include poor network coverage, temporary network problems, and issues with the device’s configuration. 

No matter the cause, this guide is created to help you troubleshoot and fix the problem. So, let’s get started!

Note: Solutions in this guide will work on any Samsung Galaxy S21 model (S21, S21 Plus, S21 Fe, and S21 Ultra models.) 

Editor’s note: We created these instructions using a Samsung Galaxy S21 running Android 13. Depending on your device’s software version, some steps and menu positions may look slightly different.

Fix 01: Restart the Device to Refresh Network

When you restart your Galaxy S21, it also refreshes the cellular network automatically, and it can fix the issue if it was caused by a temporary connection glitch.

Here’s how to restart your Galaxy S21:

  1. Press and hold the power key + volume down key together until you get the power menu.
Force restart samsung
  1. Tap on the Restart button.
Restart phone
  1. Confirm by tapping on the restarting button again.

Try making a call to your number from another device to check if you can now receive calls.

Fix 02: Turn Off Do Not Disturb Mode

The Do Not Disturb (DND) mode is another reason that prevents the device from notifying you of incoming calls. This is because, by default, this mode mutes all calls and notifications to avoid disturbances. 

If you haven’t changed the default behaviour of this mode and it’s currently enabled, it’s likely the reason why you’re not receiving calls.

To check if the DND mode is turned on, swipe down from the top of your screen to open the notification bar. Look for the Do Not Disturb icon (it looks like a circle with a line through it). If it’s highlighted, that means the mode is active.

Turn off do not disturb

However, if you can’t find the DND icon in the notification bar, you can also check it in the settings. Here’s how:

  1. Go to Settings.
  2. Tap on Notifications.
  3. Then, select Do Not Disturb.
Do not disturb
  1. If it is toggled on, tap on the toggle again to turn it off.
Turn off do not disturb

Fix 03: Check the Blocked List

If you’re unable to receive calls from certain contacts or unknown numbers, it’s possible that these numbers may have been accidentally added to your blocked list. 

Like any other Android smartphone, the Galaxy S21 has a feature that allows users to block calls and messages from specific contacts or unknown numbers. This is a useful feature for avoiding spam calls, but it can also lead to missed calls if used incorrectly.

To check your blocked list, follow these steps:

  1. Open the Phone app.
  2. Tap on the three-dot menu icon located at the top right corner of the screen.
  3. From the drop-down menu, select Settings.
Call settings
  1. Scroll down and tap on Block numbers.
Block numbers
  1. Here, you’ll see a list of all the numbers you’ve blocked.

If you find any numbers that you don’t want to block, you can easily remove them from the list. To do this, simply tap on the minus (-) icon next to the number you want to unblock. This will immediately remove the number from your blocked list and allow you to receive calls from it again.

Fix 04: Turn Off Call Barring

Call barring is another feature that can prevent your Galaxy S21 from receiving calls. Call barring is often used to block incoming calls from certain numbers or all numbers, depending on the configurations. 

If you have accidentally enabled this feature, it is the reason why you are not receiving calls.

Here’s how you can check and turn off call barring on your Galaxy S21:

  1. Open the Phone app and go to Settings.
  2. Scroll down and tap on Supplementary services.
Supplementary services
  1. Here, you’ll find the Call Barring option. Tap on it.
Call barring
  1. You’ll see several options like “All incoming calls”, “All outgoing calls”, etc. If any of these options are enabled, that means call barring is active.
  2. To disable call barring, tap on the option that is enabled. You will be asked to enter a password. If you haven’t changed it, the default password is usually “0000” or “1234”.
  3. After entering the password, the call barring will be turned off.

Fix 05: Reset Network Settings

Misconfigurations within the network settings of your Samsung Galaxy S21 also prevent incoming calls. These can be anything from incorrect APN settings to disabled options that should be enabled. 

Verifying each and every setting to identify the root cause can be a daunting task, especially if you’re not familiar with network settings.

Therefore, the most effective solution to address this is to reset your Galaxy S21’s network settings. This will revert all network-related options back to their factory defaults and fix any misconfigurations that have been preventing receiving calls.

To reset network settings:

  1. Go to Settings.
  2. Tap on General management.
  3. Then, tap on Reset.
Reset option samsung
  1. Select Reset network settings.
Reset network settings
  1. Confirm.

Fix 06: Try a Different SIM Card From Another Provider

Re-inserting the sim card

So far, we discussed software-related fixes to address the problem you are having. However, there are instances where the problem is with the device but with the network provider. 

Issues like network overloads, service interruptions, or even account-related problems can prevent you from receiving calls. To rule out these possibilities, it’s a good idea to try a different SIM card from another provider.

Follow the steps below:

  1. Power off your device.
  2. Use the SIM eject tool (or a small paperclip) and take the SIM tray out.
  3. Remove the current SIM card from the tray and replace it with the new one.
  4. Reinsert the SIM tray back into the device.
  5. Power on your device.

Once you’ve switched SIM cards, try to see if you can now receive calls. If you can, this means the problem was with your previous network provider and you should contact them for further assistance.
