Why is my Galaxy Z Fold not receiving calls?

Why is my phone not receiving calls but I can call?

One of the issues that you might experience with your Samsung Galaxy Z Fold 4 is when you are not receiving incoming calls. This can be a frustrating experience especially if you are waiting for an important call.

Here’s what you need to do to if your Samsung device can’t receive incoming calls.

Solution 1: Check cellular network signal

One of the most common reasons why you are unable to receive incoming calls is because the phone is not getting any signal from the network.

If the signal is weak or non-existent at all then you won’t be able to use some of the network services such as making or receiving voice calls or text messages.

Some of the places where the cellular signal might be weak are enclosed places such as in a building basement or in areas with no carrier towers available which will result in your phone not getting any service at all.

You can check your phone signal strength on the upper right part of the display. If it is weak then you might want to try to transfer to a different location as your current carrier might not have a good reception in your area.

If the phone has a strong signal and you can’t seem to be receiving any calls then here’s what you need to do.

Turn off the Wifi

Try turning off the WiFi switch of your Android phone and see if you can get at least a 3G signal. With the WiFi now off, try checking if you can receive calls.

Toggle airplane mode

Turning on airplane mode then turning it back off is another way of refreshing the Galaxy Z Fold 4 connection to the network towers.

  • From a Home screen, swipe up to access the apps screen.
  • Tap Settings.
  • Tap Connections.
  • Tap Airplane Mode switch to turn on.
  • Wait for a minute then tap Airplane Mode switch again to turn off.

Check if your Samsung phone is getting a signal from the network. If it is, try checking if you can receive calls.

Solution 3: Start the Galaxy Z Fold 4 in Safe Mode

Starting your Samsung Galaxy Z Fold 4 in Safe Mode is a good way to check if a third party app you downloaded is causing the incoming voice call issue you are experiencing .

When your phone runs in this mode only the pre-installed apps will be allowed to run making troubleshooting app related issues easy to do.

Solution 5: Try using a different SIM card
