If you’re facing the issue where your Android phone can send text messages but cannot make calls, you’re not alone. This problem can stem from various issues ranging from network settings to hardware malfunctions. This article provides a comprehensive guide to help you troubleshoot and resolve this issue effectively.
Understanding the Problem
Differentiating Between Call and Text Issues
Before diving into solutions, it’s essential to understand the difference between call and text functionalities. Text messaging relies on different protocols compared to voice calls. SMS (Short Message Service) uses a different part of the network compared to voice calls, which typically involve cellular voice services or VoIP (Voice over Internet Protocol) systems. Therefore, if texts are working but calls aren’t, it suggests a specific issue with the voice service or settings on your device.
Potential Causes of Call Issues
Several factors could cause your Android phone to have issues with making calls while still being able to send texts. These include problems with your network service provider, incorrect network settings, issues with your SIM card, or software glitches. Understanding these potential causes will help in diagnosing and fixing the problem effectively.
Checking Network Signal and Coverage
Verifying Signal Strength
A common reason for being unable to make calls is poor network signal. Check the signal strength indicator on your phone. If it shows weak or no signal, try moving to a different location where the signal might be stronger. Also, check if there are any known outages or maintenance work in your area that might be affecting network services.
Restarting Your Phone
Sometimes, simply restarting your phone can resolve network issues. Turn off your phone, wait for a few seconds, and then turn it back on. This action can reset your network connections and might resolve temporary glitches affecting your ability to make calls.
Inspecting SIM Card and Network Settings
Checking SIM Card Functionality
A malfunctioning or improperly inserted SIM card can cause issues with making calls. Ensure that your SIM card is correctly inserted into the SIM slot. If you have a spare SIM card or another phone, test the SIM card in a different device to see if the problem persists.
Verifying Network Settings
Incorrect network settings can also affect call functionality. Go to your phone’s settings and check if the network mode is set correctly (e.g., 4G/LTE or 3G). Ensure that the settings are configured to connect to your carrier’s network properly. Sometimes, resetting network settings can resolve connectivity issues.
Examining Account and Carrier Issues
Checking for Service Disruptions
Contact your network carrier to ensure there are no disruptions or issues with your account. Sometimes, account-related problems such as unpaid bills or service suspensions can prevent you from making calls. Confirm that your account is active and in good standing with your carrier.
Updating Carrier Settings
Carrier settings updates are crucial for ensuring your phone works correctly with your network provider. These updates can fix bugs and improve connectivity. Check if there are any updates available for your carrier settings by going to your phone’s settings and looking for system updates or carrier settings updates.
Investigating Software and App Conflicts
Updating Your Phone’s Software
Software bugs can sometimes interfere with call functionality. Ensure that your phone’s operating system is up to date. Go to Settings > System > Software Update to check for any available updates. Installing the latest software updates can fix bugs that might be affecting your ability to make calls.
Disabling or Uninstalling Problematic Apps
Certain apps, particularly those related to call blocking or security, can interfere with your phone’s call functionality. If you’ve recently installed any new apps, try disabling or uninstalling them to see if this resolves the issue. Additionally, check your phone’s permissions to ensure that no app is restricting your call functionality.
Performing a Factory Reset
When to Consider a Factory Reset
If all else fails, performing a factory reset may be necessary. A factory reset will restore your phone to its original settings, which can resolve persistent software issues affecting call functionality. However, this should be a last resort as it will erase all data on your phone. Ensure you back up your important data before proceeding.
How to Perform a Factory Reset
To perform a factory reset, go to Settings > System > Reset options > Erase all data (factory reset). Follow the on-screen instructions to complete the process. After the reset, set up your phone again and check if the issue with making calls has been resolved.
Seeking Professional Help
When to Consult a Technician
If you’ve tried all the above troubleshooting steps and still cannot make calls, it may be time to seek professional help. There could be an underlying hardware issue or more complex software problem that requires expert attention. Visit an authorized service center or contact the manufacturer’s support team for further assistance.
Preparing for a Repair or Replacement
Before taking your phone for repair, make sure to back up all your data and remove any SIM cards or external memory cards. This ensures your data is safe and that the technician can work on your phone without any complications.
Exploring Advanced Troubleshooting Options
Checking for Interference
Sometimes, electronic interference or physical obstructions can affect your phone’s ability to make calls. Ensure that there are no other devices or electronic equipment near your phone that might be causing interference. Additionally, make sure there are no physical obstructions or damage to the phone’s antenna or SIM card slot that could impact call functionality.
Testing in Safe Mode
Booting your phone in Safe Mode can help determine if third-party apps are causing the issue. Safe Mode disables all third-party apps temporarily, allowing you to see if the problem persists. To enter Safe Mode, press and hold the power button, then long-press the “Power off” option until the Safe Mode prompt appears. If calls work in Safe Mode, a recently installed app might be the culprit.
Advanced Network Troubleshooting
Resetting Network Settings
If network-related issues persist, consider resetting your network settings. This action will restore all network settings to their default values, which can resolve problems with connectivity. Go to Settings > System > Reset options > Reset Wi-Fi, mobile & Bluetooth. Be aware that you’ll need to reconnect to Wi-Fi networks and reconfigure Bluetooth devices afterward.
Checking VoLTE and Call Settings
Voice over LTE (VoLTE) can impact call functionality if not properly configured. Ensure VoLTE is enabled in your phone’s settings if your carrier supports it. Go to Settings > Network & Internet > Mobile Network and check if VoLTE is turned on. Also, verify that call settings are properly configured and not set to restrict calls under any specific conditions.
Dealing with Hardware Issues
Inspecting for Physical Damage
Physical damage to your phone can affect its call functionality. Inspect your device for any visible damage, such as cracks or dents, especially around the areas where the microphone, speaker, and SIM card slot are located. If you suspect physical damage, you may need to visit a repair center for a thorough inspection.
Checking Internal Components
Internal component issues, such as a malfunctioning antenna or damaged circuitry, can affect call performance. If you’re comfortable with hardware troubleshooting, you can open the phone to check for loose connections or damaged parts. However, this should be done cautiously or by a professional to avoid further damage.
Addressing Carrier-Specific Issues
Verifying SIM Card Compatibility
Ensure that your SIM card is compatible with your phone model and network. Some phones may not support certain types of SIM cards or network bands. If you’re using a SIM card from a different carrier or region, compatibility issues could arise. Check with your carrier for compatibility information.
Updating or Replacing Your SIM Card
If your SIM card is old or damaged, it might be worth updating or replacing it. Visit your carrier’s store to get a new SIM card or check if they offer an online replacement service. New SIM cards can resolve issues related to outdated technology or physical damage.
Conclusion
Recap of Troubleshooting Steps
In summary, if your Android phone can send texts but cannot make calls, there are multiple potential issues to investigate. Start by checking your network signal, inspecting your SIM card and network settings, and examining account or carrier issues.
