When an iPhone user calls someone, the call may fail for various reasons. It could be due to a weak signal or lousy reception in the area, or problems with the other person’s phone. If a number is blocked, then it may also cause the iPhone call failed. Additionally, if you are trying to call international numbers, this can also cause issues. Other potential causes include incorrect contact information entered into your device or carrier-related problems such as network outages. If you’re having trouble making calls with your iPhone, check that all your contact information is correct and that there’s no issue with your carrier service. If these don’t help, try using Wi-Fi Calling or restarting both devices involved in the call attempt before reaching out to customer service for assistance.
Reasons for Call Failed iPhones

The most common reason for a call failing on an iPhone is network connection issues. It could be related to the phone’s SIM card not being inserted correctly, an incorrect APN setting, or inadequate coverage. Another common issue is hardware related and can involve damage to components such as the microphone or speaker, preventing calls from connecting. Similarly, it may also be caused by faulty accessories, such as headphones connected to your phone. Finally, check if any of the settings in your phone, such as Do Not Disturb mode, are enabled that could prevent calls from connecting. If all else fails, restarting your phone may help fix any temporary glitches in the system that could cause a call-failed iPhone issue.
Hardware Problem
Hardware problems can range from minor issues to severe damage. A typical hardware problem is a broken or cracked screen on a device, such as an iPhone. This type of issue usually results in the phone not working correctly and is easily recognizable by the black lines running across the display or a lack of responsiveness when trying to make a call. While this damage requires professional repair, other hardware problems can be fixed with basic troubleshooting. For example, if your Apple Watch isn’t sending notifications or messages, it may be due to low battery levels on both devices; simply charging your watch and reconnecting it to your iPhone should resolve this issue. Additionally, if you’re having trouble connecting Bluetooth headphones or speakers to your device, ensure they are correctly paired and check for any software updates, as outdated versions could interfere with the connection.
Software Issues
Software issues can be complex and challenging to diagnose. One common issue is associated with a call failing on an iPhone. It could be due to an outdated operating system or other conflicts with the phone’s software. To resolve this, users should first check that their phone has the most up-to-date version of iOS installed by going into their settings and tapping “General” followed by “Software Update” to install any available updates. If no updates are available, they should try restarting their device, which can often clear up any software issue.
Additionally, users should check for any open apps running in the background, as these can cause conflicts with incoming calls and negatively impact call quality. To do this, double-press the home button to view open apps and swipe them away if necessary. Taking these steps can resolve any software issues causing a failed call on an iPhone.
Network Issue
Network issues can appear in many different ways. One of the most common is when someone tries to make a call with their iPhone, but it fails to go through. The first thing to check is whether airplane mode has been activated on the phone, as this will prevent any calls from going through regardless of network connection. If airplane mode has been turned on, simply deactivating it should allow the user to make and receive calls again. Another networking issue could be that there needs to be more signal strength in an area for a call to go through, mainly if the user is in an area with limited reception or indoors where thick walls are blocking the signal. Moving closer to a window or outside often helps restore signal strength and allows the user to make and receive calls again.
Battery and Charging Problems
If you are experiencing battery and charging problems on your iPhone, there are a few things you can do to help resolve the issue. First, checking that the device has enough power to make or receive calls is essential. If your iPhone does not have sufficient power, it may fail to connect when attempting a call. You can check the power level of your phone by pressing the Home button and checking for an icon on the screen that shows the remaining battery life.
If you already have enough power but still experience issues making or receiving calls, try forwarding all incoming cellular calls directly to voicemail. To do this, go into Settings > Phone > Call Forwarding > Switch “Forward Calls” on and select “Forward All Calls” from the options given. Then save your changes by selecting “Done” in the top right corner of the screen. It will prevent incoming calls from connecting until you turn off call forwarding again.
Troubleshooting Steps
The first step to troubleshooting a failed call on an iPhone is to check the contacts list. Check if the person you are trying to call is in your contacts and that the phone number associated with them is correct. If they are not in your contacts list or the number needs to be corrected, add their contact information and try calling again.
Next, check all your settings related to calls. Make sure aeroplane mode is off. Also, check that Do Not Disturb mode isn’t enabled and that “Silence Unknown Callers” isn’t selected, as these can prevent incoming calls from coming through. Additionally, examine other applicable settings for phone calls, such as Wi-Fi Calling or 4G LTE Calling, so that they are turned on if needed for your carrier network. Restarting your device may help reset any potential problems with how it processes incoming calls. To do this,
- Hold down the power button (until you see the “Slide to Power Off” slider appear)
- Slide it across to turn off the device
- Wait a minute to turn it back on again(press and hold the power button until you see the Apple logo)
Update Software
Software updates are essential as they often contain improvements that enhance the user experience. For example, updating iOS software can provide bug fixes and new features such as FaceTime video calling. Updating your Apple device to the latest version of iOS is relatively simple and only takes a few steps. First, users should connect their devices to a secure Wi-Fi network and have a sufficient charge on the device’s battery. Then they must go to Settings > General > Software Update and tap “Download and Install” if an update is available. Some updates may require more than one step, so users must follow all onscreen instructions carefully while updating. Lastly, iPad owners must ensure their device is running iOS 13 to be compatible with FaceTime.
Restore iPhone as Last Resort
When all else fails, and you are left with no other option, restoring your iPhone can be done as a last resort. It is important to note that this process will erase all of the data on your phone, including contacts and photos, so it is wise to back up your device first. Connect your device to an iTunes computer to begin the iPhone restore process. Once connected, select ‘Restore’ from the Summary tab in iTunes and follow the onscreen instructions. If needed, turn off Find My iPhone before proceeding with the restore. With this option selected, you will be prompted to select either ‘Set Up as New’ or ‘Restore from Backup. Select Restore from Backup if you have a backup of your device before beginning the restoration process. Otherwise, select Set Up as New to start resetting your device.
Additionally, check available storage space on your device by navigating to Settings > General > About; if there is too little space available (less than 1GB), delete any unnecessary apps or files stored to free up more storage before attempting a restoration. Following these steps wholly and carefully restoring an iPhone as a last resort should help solve any call-failed issues experienced previously.
Contact Apple Support
Apple offers many avenues to get support and help with your iPhone. Calling Apple Support is one of the quickest ways to get an answer to any issue you may be having. To contact Apple Support, dial 1-800-MY-APPLE (1-800-692-7753). This pops up with a box to select your language, country, or region before reaching an Apple Support expert. Once on the phone with an agent, provide them with details about your issue so they can quickly assist you. Depending on the issue’s complexity, it may take more than one call for resolution. If this is the case, make sure that you note down any advice given by the representative so that you don’t have to start from scratch when calling back again.
Tips for Avoiding Future Issues
Be sure to back up your data regularly to prevent data. You should also use a secure passcode and avoid downloading suspicious apps or websites that could contain malware. Keep your software updated with the latest security patches, which will help protect your device from potential threats. Finally, always use a reputable repair shop when dealing with hardware issues to ensure quality repairs and parts.
Conclusion
In conclusion, you can take a few steps to troubleshoot the iPhone call failed issue. The first step is to check the device’s signal strength by looking at the bars in the iPhone’s upper-left corner. If it is low, try moving to a different location with better coverage. An outdated version of iOS could also cause it; updating iOS may solve this problem. Also, ensure to turn off Airplane mode and restart your phone to resolve any issues you might have. Lastly, contact your carrier or Apple Support for further assistance if all else fails.
