Fix Unable to Make Or Receive Phone Calls on Samsung Galaxy S21
Check the Signal Strength
Have you checked the signal strength? Normally it should be at least two bars to make or receive calls and use internet services without worry. You might find it hard to make or receive calls if you’re in Basement, Lift, etc.
Restart the Device
Force rebooting the app has a considerable effect on the device and firmware. If the software is crashing and causing random errors, you should first restart the Samsung S21.
Press and hold the Power button and Side button until the SAMSUNG logo appears.
Force Close Phone App
Another worth trying workaround is to force stop the Phone App that is performing irregular activities while receiving or making the calls. Doing this will completely shut down the phone app from the background.
- Go to the Settings app on your device.
- Tap on Apps.
- Scroll down to Phone App.
- Tap on Force stop.
Clear Phone App Cache
The cache is the supportive files that make the operations on the phone easy, however, it’s not always true. Besides, it’s great if you periodically clear the cache of apps.
- Open the Settings app.
- Go to Apps.
- Select Phone App.
- Tap Storage > Clear cache.
- And then Clear data.
Toggle Airplane Mode
While the Airplane Mode is enabled, your device disconnects from all the Wireless Connections including Cellular network, Wi-Fi, and more. All you can do is, tap on the Airplane mode or Flight mode button, and after 2-3minutes disable the Airplane Mode. Also, it can be done from the Settings > Connections > Airplane mode.
Most of the time, resetting settings on the device fixes many problems that can’t be identified. It won’t delete the personal data, but the customized settings will be reset to default.
- Navigate to the Settings app.
- Tap General management.
- Tap Reset.
- Again select Reset.

Make Sure Do Not Disturb Mode is Disabled
Galaxy S21+ Can make calls but can’t receive them?
