How to Fix iPhone Dropping Calls After Updating to iOS 13: 7 Ways

1. Reboot Your Device.

We will assume that you have the latest version of your iOS since the dropping calls issue started after the update. But if you’re not sure about it, you can always check for any pending iOS updates right on your iPhone. If you wish for a full backlog of every iOS update released by Apple to keep track of changes and updates then this is what you’re looking for.

Let’s check if there are any latest, pending updates on your iPhone:

  1. Simply go into your Settings app, General, and then tap on Software Update.

  1. If there are any pending updates waiting to be installed, simply Download and Install them and wait for the installation process to restart your iPhone. Please be aware to not turn off your iPhone midway as it updates as this could wipe out all of the data on your iPhone.

Now that you have the new updates and settings applied, your calls should work properly now.

2. Disable Possible Settings Conflict.

There is a feature on your iPhone that blocks all unregistered numbers so that they will not be able to disturb you. Apparently, some users have discovered that turning off this feature have somehow stopped their calls from dropping. To do that, you just need to open your iPhone’s Settings, then Phone option, and then tap Silence Unknown Callers option to disable it.

Another feature that is possibly causing the issue is the Wi-Fi Calling option. This could sometimes cause your iPhone to route from Cellular to Wi-Fi network. Technically, if this happens during a call, it will be disconnected (which could be the reason why your calls get dropped). So try to disable the feature by going to the Settings, then Phone option and tap on Wi-Fi Calling.

If disabling these features have stopped your calls from dropping, it will need to stay disabled for now. But if you need these features, we advise that you file a bug report to Apple Support. It is crucial that they gather information about the bugs so they can release a fix for it.

However, if you are still experiencing the same issue, proceed to the next method.

3. Check for Carrier Update.

It is possible that your iPhone does not have the latest, updated settings with your carrier network. Carrier updates often get forgotten by us, iPhone users since they usually get updated on their own in the background of our iPhones. However, it is important to go into your carrier settings on your iPhone and check if it is up-to-date since carriers often release updates to maintain the network and fixing issues such as the one you’re having now.

Here’s how you check if you have the updated configuration of your carrier network on iPhone:

  1. First, connect your iPhone to the internet via Wi-Fi.
  2. Then tap the Settings on your iPhone, then General option and then the About option.
  3. Now find the Carrier on the screen and give it a few seconds to check for new updates.

  1. Tap on the Update and follow the instructions to complete the update process.
  2. Finally, after the process, reboot your iPhone to make sure that your device has applied the new settings.

Now that you have updated your iPhone’s carrier settings, you will be able to make calls with a more stable connection.

4. Remove and Re-insert the SIM Card.

Sometimes we just assume that everything is fine when we drop our iPhone. But the impact might have misaligned the SIM card and caused this issue. It’s important to make sure your SIM card is securely in place to function properly. This is usually the root cause of issues like the SIM card not being detected, no cellular data connection, and the famous No Service indicator on the iPhone.

Here’s how you remove and reinsert your SIM card properly:

  1. Go ahead and turn off your iPhone by going to Settings, then General and then Shutdown.
  2. Then, insert the SIM Eject tool (this is usually included in your iPhone box) or a paper clip into the small hole on the right side of your device (as shown below). Check out the SIM tray location of the different iPhone versions.iPhone Dropping Calls After Updating to iOS 13
  1. Push it in slightly to eject the SIM card tray and completely remove it from the iPhone slot.
  2. Now, remove the SIM card from the tray and place it again with the metal chip facing downward.
  3. Re-insert the SIM card tray into the iPhone slot and push it in towards the device until it clicks into place.
  4. Finally, start up your iPhone and make sure you don’t get any SIM Card error. If there is an error, repeat the process from Step 1.

Now that you are able to secure your SIM card inside your iPhone, you can now make your calls with no issues. But if you are still experiencing the call drops, proceed to the next method for the next possible fix.

5. Reset Network Settings

It is possible that the network settings on your iPhone have been corrupted. To fix this issue, you usually have to restore the network settings to its default values to remove conflicts.

Here’s how you reset network settings on your iPhone:

  1. Go ahead and open your iPhone’s Settings, then tap General, and then tap Reset option.
  2. Next, find and choose Reset Network Settings.

  1. If you are asked for the device passcode, provide it in the space provided.
  2. Finally, Confirm to finalize the process.

Now that you have removed the conflicts of the network settings on your iPhone, you will be able to make calls without any interruptions. But if you are still having the same issues, check out the next method.

6. Contact Carrier for Support

There is a possibility that your network settings on your SIM card are already outdated, especially if you are using it for a very long time. Since your carrier constantly upgrades the network, your SIM will need to catch up with the settings. You may have updated your iPhone’s carrier settings but apparently, you do not have control over your SIM Card settings.

To make sure, you need to contact your carrier’s support to check on the settings on your SIM Card.

We have listed down all the major carrier’s support pages here below for you to use:

Verizon Support

If they have successfully updated it, try it on other phones and make sure it does not drop the calls. But there is a possibility that your SIM card may be really old and needs to be replaced. Depending on your account, you still may be able to retain your number even if they provided you with a new SIM card.

Getting a new SIM card has been found to have helped many of our readers here on Saint and it could possibly be the solution for you. Again, it’s important to consult with the carrier support first to diagnose whether the issue really lies with the SIM card before switching to a new SIM card.

7. Reset iPhone and Setup as New

It is also possible that there is an untraceable corrupted file or setting on your iPhone that is causing this issue. There are a lot of causes as to why this happens but one way to fix this problem is to restore your device to its default factory settings. Before doing this, make sure you have a backup of your iPhone’s data. Here’s how you can do it:

  1. Go ahead and open the Settings of your iPhone, then tap on General option, and then tap the Reset option.
  2. Then, choose and tap Erase All Content and Settings option.


  1. Next, you will be seeing a message to create a backup and then erase the device or erase it right away, select Erase Now.
  2. If asked, provide the passcode of your iPhone for process confirmation.
  3. Now, wait for the Apple logo to show and to finish the reset process.
  4. After that, wait for the screen to show ‘Hello‘ message.
  5. Finally, wait for your iPhone to sync in and set it up as new.

Now that you have restored your iPhone to the factory default state, all possible conflicts are removed and your iPhone is as good as new similar to when you first got it.

Additionally, be sure to check Method 2 for a possible conflict, just in case. Try giving a test call with someone to see if the issue persists. You should be able to call now without any drops.

8. Contact Apple for Support

It is possible that your iPhone has conflicts and corrupted files that needed advanced troubleshooting steps. There is another way to restore your iPhone on a firmware level but only Apple-certified technicians are allowed to do it. This is to preserve the warranty that you have on your iPhone. They can also check the hardware part of your device and have it replaced. All of these services are available at your nearest Apple Store. Be sure you know your warranty options before you go there.
