Key Takeaways
There could be several reasons why you can’t make or receive calls on your Samsung Galaxy S7. It may be due to a network issue, a problem with your SIM card, a software glitch, or a hardware issue. Try restarting your phone, checking your signal strength, ensuring that airplane mode is off, and verifying your SIM card is properly inserted. If the problem persists, contacting your service provider or visiting a technician for further diagnostics may be necessary.

Check Network Connectivity

First, make sure that your Samsung Galaxy S7 is connected to a stable and strong network signal. Try moving to a different location or stepping outside to see if your signal improves. If you are using Wi-Fi calling, ensure that your Wi-Fi connection is strong and stable. You can also try toggling airplane mode on and off to reset the network connection.

Next, check your network settings to ensure that data and calling features are enabled. Go to Settings > Connections > Mobile networks and make sure that the “Mobile data” and “VoLTE calls” options are turned on. Additionally, ensure that the network mode is set to the appropriate option (e.g., LTE/3G/2G). If you are in an area with poor network coverage, switching to a different network mode may help improve your connectivity.

If you are still unable to make or receive calls after checking these network connectivity factors, contact your mobile service provider to verify if there are any network outages or issues in your area. They may also be able to assist you with troubleshooting specific to their network and services.

Restart Your Phone

If you are experiencing difficulty making or receiving calls on your Samsung Galaxy S7, the first troubleshooting step to try is to restart your phone. Restarting the device can resolve various temporary issues related to call connectivity.

To restart your Samsung Galaxy S7, simply press and hold the power button located on the right side of the device. After a few seconds, a menu should appear on the screen. Tap on the “Power off” option and wait for the phone to completely shut down. Once the phone is off, press and hold the power button again until the Samsung logo appears, indicating that the device is restarting.

If you have tried restarting your phone and are still unable to make or receive calls, it may be necessary to proceed to the next troubleshooting steps. However, in many cases, a simple restart can resolve the issue, so it is always a good initial step to take when experiencing phone call problems on your Samsung Galaxy S7.

Verify Airplane Mode Status

To troubleshoot your Samsung Galaxy S7’s calling issues, the next step is to verify the Airplane Mode status. Airplane Mode disables all wireless signals, including cellular, Wi-Fi, and Bluetooth connections. To check if Airplane Mode is enabled, swipe down from the top of the screen to access the Quick Settings panel. Look for the Airplane Mode icon – a small plane – and ensure it is not highlighted. If it appears pressed, tap it once to deactivate the mode.

Enabling Airplane Mode can often be accidental, especially if you use the Quick Settings panel frequently. Once Airplane Mode is turned off, try making a test call to see if the issue is resolved. If the call is successful, then the problem was likely caused by Airplane Mode. If not, move on to the next step in the troubleshooting guide to continue investigating and resolving the calling problem on your device.

Ensure Call Settings Are Configured Correctly

When troubleshooting issues with making or receiving calls on your Samsung Galaxy S7, it’s important to ensure that the call settings are configured correctly. Start by checking the call forwarding settings to ensure that calls are not being redirected to another number, which can cause issues with receiving calls. You can access call forwarding settings by navigating to the Phone app, selecting the More option, and then locating the Call settings where you can verify and adjust call forwarding options.

In addition, verify that the call barring settings are not enabled for the types of calls you are trying to make or receive. These settings can block calls to certain numbers or from certain types of services, so it’s essential to review and adjust them as necessary. You can access call barring settings within the Phone app’s More menu, under Call settings, to ensure they are not hindering your ability to make or receive calls. By double-checking these call settings, you can troubleshoot potential issues and ensure that your Samsung Galaxy S7 is configured correctly for making and receiving calls.

Update Your Phone’S Software

To ensure that your Samsung Galaxy S7 is functioning at its best, regularly checking for software updates is crucial. New software updates often contain bug fixes and improvements that can help resolve issues related to call connectivity. To update your phone’s software, go to Settings, then scroll down and select About Device. From there, tap on Software Update and then select Update.

If an update is available, follow the on-screen instructions to download and install it. Keep in mind that it’s important to have a stable internet connection and sufficient battery life before initiating a software update. After the update is complete, restart your phone and check if the issue with making or receiving calls has been resolved. If the problem persists, consider contacting Samsung support for further assistance or visiting a certified service center for a thorough diagnosis and potential resolution. Keeping your phone’s software up to date not only helps in resolving existing issues but also enhances overall performance and security.

Remove And Reinsert Sim Card

To troubleshoot call-related issues on your Samsung Galaxy S7, removing and reinserting the SIM card can be an effective solution. A faulty connection between the SIM card and the phone’s reader can lead to call disruptions. To address this, power off your device, locate the SIM card tray, and use the eject tool to remove the SIM card. Inspect the SIM card for any damage or debris, and carefully reinsert it back into the tray.

Once the SIM card is reinserted, power on your device and check if the call issues have been resolved. This process can help establish a secure and stable connection between the SIM card and your phone, potentially resolving any call-related problems. If issues persist after reinserting the SIM card, consider contacting your service provider to verify if the SIM card itself is functioning properly, or if there are any network-related issues affecting your device.

Check For Hardware Issues

If you’ve gone through the software troubleshooting steps and are still unable to make or receive calls on your Samsung Galaxy S7, it’s time to check for hardware issues. Start by inspecting the physical condition of your phone, ensuring that there are no visible damages to the screen, buttons, or ports. If you notice any physical damage, it may be affecting the phone’s ability to function properly, and you may need to seek professional repair services.

Additionally, consider testing the phone with different accessories, such as headphones or a Bluetooth headset, to see if the issue is related to the phone’s built-in speaker or microphone. Furthermore, checking the signal strength in different locations can help determine if the issue is related to the phone’s antenna or network connectivity. If you have access to a spare SIM card, try inserting it into your phone to rule out any issues with the SIM card slot. If none of these steps resolve the problem, contacting Samsung’s customer support or visiting an authorized service center may be necessary to diagnose and address any underlying hardware issues.

Contact Samsung Support

For more complex issues or persistent problems with your Samsung Galaxy S7, it may be best to contact Samsung support directly. Their customer service team can provide personalized assistance and troubleshooting guidance tailored to your specific situation.

To get in touch with Samsung support, you can visit their official website and access the support section, where you’ll find options for live chat, email support, or phone assistance. You can also visit a Samsung service center in person if there’s one available in your area.

When contacting Samsung support, be sure to have your device’s information, such as the model number and software version, ready to provide the support team. This will help them better understand your device’s specifications and quickly address any technical issues you may be experiencing.
