Carrier Outage: Sometimes, the problem can be with your service provider. Power outages or maintenance work that is being carried out on the network may impede the service temporarily.
SIM Card Problems: If the SIM card is defective or not inserted correctly, it might lead to making calls being impossible.
2. Software Problems
Software Glitches: Temporary issues or bugs in the software can stop a phone from executing calls. Usually, these problems can be solved by a simple phone restart or update of the software.
Outdated Software: Using a non-updated version of the operating system or firmware may cause incompatibility between network services and device.
Third-Party Apps: Some applications that are not part of the operating system can disrupt the cell phone’s call-making ability, especially if they are apps related to communication or network management.
3. Hardware Issues
Microphone Problems: In case the microphone does not function properly, the person on the opposite side of the call might not hear you, thus resulting in failed calls.
Antenna Damage: Impact on the signal reception and transmission due to damage to the mobile phone off the internal antenna can result in making or receiving calls being difficult.
4. User Settings
Airplane Mode: Wireless communication, including phone calls, becomes disabled if Airplane Mode is on.

Troubleshooting Steps

1. Check Network Signal and Carrier Service
Signal Strength: Ensure that your network signal is good enough. Check the signal bars on the status bar of your mobile phone. In the case of weak signal, try to change your position to some better coverage area.
Carrier Status: Get in touch with your carrier and inquire if they are experiencing any outages or are doing any maintenance work in your vicinity. Alternatively, you can check their website or social media pages for such information.
2. Inspect the SIM Card
Reinsert the SIM Card: Switch off your mobile phone, take out the SIM card, and put it back in its place correctly. Check that the SIM card is not scratched or has dirt on it.
Test with Another SIM Card: If you can, use another SIM card to find out if the problem still exists. This way you will know whether the SIM card is faulty or your phone is the cause of the trouble.
3. Restart Your Phone
Soft Reset: A simple restart can take care of numerous temporary software problems. Hold down the power button then pick “Restart” from the dropdown.
4. Update Software
Check for Updates: Make sure your device has the most recent software version. Go to Settings > Software Update > Download and Install to search for any available updates and install them.

Network Reset: One of the solutions to connectivity problems is to reset network settings. Go to Settings > General Management > Reset > Reset Network Settings to do so. All Wi-Fi, Bluetooth, and mobile data settings will be reset, but no personal data will be removed.
6. Check for Third-Party App Interference
Safe Mode: The first thing you should do is check by booting your phone into Safe Mode if a third-party app is responsible for the problem. To do this, press and hold the power button, then tap and hold the “Power Off” option until you see the Safe Mode prompt. Choose the “Safe Mode” option. If your phone produces no problems during calls in Safe Mode then a third-party app is the one causing the issue. To find out which one, uninstall the apps that you have installed most recently.

Call Barring: Make sure that the call barring settings that are blocking calls are not activated. Open the Phone app > More options (three little dots) > Settings > Supplementary services > Call barring.
8. Factory Reset
Backup Data: It is wise to take factory reset as the last alternative only after all other options have been exhausted. The process wipes out all files, apps, and settings on the device so be sure to copy over your important files beforehand.
Factory Reset: Navigate to Settings > General Management > Reset > Factory Data Reset. Then follow the instructions to finalize the reset.
