How to Fix iPhone 13 Cutting Out During Calls

Now that we've looked at the possible reasons why your iPhone 13 is cutting out during calls, it's time to move on to the practical solutions. In most cases, this issue can be resolved with a few simple troubleshooting steps related to your network, SIM card, or system settings. Below, we'll walk you through the most effective methods to help restore stable and uninterrupted call quality on your device.

Fix 1: Enable LTE on Your iPhone

LTE is an important feature on iPhone that can improve voice quality and data connections. Thus, when your iPhone cuts out during calls, you are suggested to enable the LTE following the detailed steps below.

Step 1. Open the Settings app and tap on Cellular.
Step 2. Tap on Cellular Data Options. If you have multiple lines (like an eSIM and a physical SIM), you will need to select the specific line first to see these options.
Step 3. Select Voice & Data.
Step 4. Choose LTE from the list.

Note

If you see "5G On" or "5G Auto" selected, switching to LTE can often stabilize your connection if you are in an area with weak 5G coverage, which helps prevent those frustrating call cut-outs.

Fix 2: Use Voice Isolation Mode

Voice Isolation Mode on your iPhone 13 helps reduce background noise and focus on your voice, making calls clearer and more consistent. By filtering out sounds like wind, traffic, or surrounding conversations, it improves audio quality and can prevent your voice from sounding like it is cutting in and out, especially in noisy environments.

Step 1. Initiate a standard phone call or a FaceTime audio call to activate the hidden microphone menu.
Step 2. Access your system shortcuts by swiping down from the top-right corner of the screen to open the Control Center.
Step 3. Locate the Mic Mode button (indicated by a microphone icon) at the top right of the Control Center and tap it.
Step 4. Select Voice Isolation from the list of available modes to enhance your voice clarity and reduce call cut-outs.

Note

This setting is "sticky," meaning once you enable it for a contact or call type, your iPhone will remember to use it for future conversations.

Fix 3: Reset Network Settings

If your iPhone 13 is experiencing call dropouts or audio cutting out during calls, the issue may be related to corrupted or misconfigured network settings. Resetting the network settings can restore default connectivity configurations (Wi-Fi, cellular, VPN, etc.) without deleting your personal data, and often resolves persistent call stability problems.

Step 1. Open the Settings app on your iPhone.
Step 2. Tap General. Scroll down and select Transfer or Reset iPhone.
Step 3. Tap Reset at the bottom of the screen.
Step 4. Choose Reset Network Settings. Enter your passcode if prompted and confirm the action.

After the reset, your iPhone will restart, and you may need to reconnect to Wi-Fi networks and re-enter passwords.

Fix 4: Check for Carrier Updates

In some cases, if you meet this calling issue, there is something wrong with the carrier. To avoid such issue from happening again, updating your carrier can be a good choice for you.

Step 1. Launch Settings on your iPhone and then choose About.
Step 2. Wait for a while and you will see a message showing Carrier Settings Update.
Step 3. After that, choose Update from the pop-up window.

Fix 5: Reinsert SIM Card

If your iPhone continues to experience call dropouts or intermittent audio issues, the SIM card may be loose, improperly seated, or experiencing a temporary connection glitch. Reinserting the SIM card can help re-establish a stable connection to the carrier network and resolve calling interruptions.

Step 1. Turn off your iPhone. Eject the SIM card tray using a SIM tool or paperclip.
Step 2. Remove the SIM card, then place it back into the tray correctly.
Step 3. Reinsert the tray and turn your iPhone back on.
Step 4. Check if the issue is fixed after restart.

FAQs About iPhone 13 Cutting Out During Calls

Why is my iPhone 13 cutting out when I have full bars?
Even with a strong signal, audio can cut out if your phone is struggling to switch between 5G and LTE networks. This is known as a "handover" issue. Modern iPhones often try to maintain a 5G connection even if the signal is unstable, which can lead to momentary gaps in voice data.
Will a new SIM card fix call cutting out?
It might. If you are using an older physical SIM card from a previous phone, it may not be fully compatible with the latest 5G protocols on iOS 26. Switching to an eSIM or requesting a 5G-ready SIM from your carrier can often resolve persistent connection drops that software resets cannot fix.
Can "Attention Aware" features cause audio issues?
While rare, some users report that the iPhone's sensors can dim the screen or change audio behavior if they don't detect you are looking at the device. If you hold the phone at an unusual angle during a call, the proximity sensor might glitch, causing the audio to clip.
Step 1. Go to Settings and select Face ID & Passcode.
Step 2. Locate Attention Aware Features and toggle it off to test if the sensor interference is causing the audio drops.

Conclusion

All in all, we have listed 6 viable ways for you if your iPhone cuts out during calls. You can try these methods and fix your problem easily in no time. If you want to use a professional app to solve this problem, TunesKit iOS System Recovery is your best choice. It's easy to use and won't cause data loss.
