But fret not. In this guide, we’ll help you troubleshoot voicemail issues on your iPhone so you can start using it again.

What to do if iPhone voicemail is not working

There could be several reasons why voicemail is not working on your iPhone correctly. It might be due to incorrect settings, a software glitch, or an issue with your carrier. 

In most cases, simply restarting your iPhone can resolve the problem. But if it doesn’t, you can follow the troubleshooting steps below to fix it.

  1. Ensure voicemail is set up correctly on your iPhone
  2. Force close and relaunch the Phone app
  3. Turn cellular data off and on again
  4. Make sure call forwarding is turned off
  5. Check for iOS software updates
  6. Check for a Carrier Update
  7. Reset iPhone’s network settings
  8. Contact your phone carrier

1. Ensure voicemail is set up correctly on your iPhone

If you’re unable to access or use voicemail on your iPhone, the first thing you need to do is ensure that you’ve set up voicemail correctly. Sometimes, you may need to set up voicemail all over again if you’ve recently installed an update, switched carriers, or changed your cellular plan.

To check if the voicemail is set up correctly on your iPhone, open the Settings app and tap on Phone. If you’re able to locate the Change Voicemail Password option at the bottom, then voicemail is already set up, and you’re good to go.

If you can’t find the Change Voicemail Password option, then you must set up voicemail on your iPhone from scratch.

  1. Open the Phone app and go to the Voicemail tab.
  2. Tap on Set Up.
  3. Create a voicemail password and record your custom greeting to complete the setup.

2. Force close and relaunch the Phone app

If voicemail seems non-functional, even if it’s set up correctly, it could be that you’ve run into a temporary software issue related to the Phone app. Force-closing and relaunching the Phone app can help in this case.

  1. Access the app switcher on your iPhone.
  2. Swipe up on the window for the Phone app to close it.
  3. Then, open the Phone app and check if voicemail is working.

3. Turn cellular data off and on again

Sometimes, turning cellular data off and back on again can resolve problems related to voicemail. Although it may seem rudimentary, this process refreshes your device’s cellular connection, which may clear up any temporary glitches or connectivity issues that could be interfering with the voicemail functionality. Here’s what you need to know:

  1. Swipe down from the top-left corner of the screen to bring up the Control Centre.
  2. Tap the green Cellular Data icon to turn off data.
  3. Tap the icon again to turn it back on.
Turn off cellular data from control center or from settings

Alternatively, you can open the Settings app, tap Cellular, and use the Cellular Data toggle.

4. Make sure call forwarding is turned off

If you’ve enabled call forwarding on your iPhone, it can prevent your calls from going to voicemail. To ensure that this isn’t the reason why voicemail isn’t working on your iPhone, ensure that call forwarding is turned off, like so:

  1. Open the Settings app on your iPhone.
  2. Navigate to PhoneCall Forwarding.
  3. Then, toggle off Call Forwarding.

    Tap phone tap call forwarding toggle on call forwarding in settings

5. Check for iOS software updates

If call forwarding is already turned off, but you still can’t use voicemails on your iPhone, you may have run into a software bug and need to update your iPhone. Software updates often include bug fixes or improvements that can resolve various problems on iPhone, including those related to voicemail.

  1. Open the Settings app on your iPhone. 
  2. Navigate to General Software Update.
  3. Tap Update Now if an update is available.

  4. Enter your iPhone passcode when prompted, and let the device update.

6. Check for a Carrier Update

Besides installing the latest version of iOS, installing the latest carrier settings update can also help you fix issues related to voicemails. Carriers occasionally roll out carrier settings updates to enable new features and resolve network-related issues on iPhones. Updating your device to the latest version ensures everything keeps working smoothly.

  1. Open the Settings app on your iPhone. 
  2. Navigate to General.
  3. Tap About.
  4. If a Carrier Settings Update dialog pops up, tap Update.

    Check for carrier updates

7. Reset iPhone’s network settings

Misconfigured network settings can often lead to unusual issues on iPhones. If your iPhone’s voicemail is not functioning, resetting the network settings can help. This action will remove all saved Wi-Fi networks, as well as any Bluetooth connections on your device, and revert the APN settings to the default state. 

  1. Open the Settings app on your iPhone. 
  2. Go to General and tap Transfer or Reset iPhone.
  3. Tap Reset and select Reset Network Settings.

  4. Enter your iPhone’s Lock Screen passcode.
  5. Tap Reset Network Settings again.

8. Contact your phone carrier

If you’ve tried everything, but nothing seems to work, it’s a good idea to contact your carrier for assistance. It’s possible that your iPhone’s just fine, but there’s an issue on the carrier’s end that needs to be addressed.

Depending on the phone carrier, you can use the following customer helplines:

  • T-Mobile: 1-800-937-8997
  • Verizon: 1-800-922-0204
  • AT&T: 1-800-331-0500
Is voicemail on iPhones available worldwide?

All iPhones support voicemails, irrespective of their region. However, whether you can use this feature worldwide or not depends on the cellular providers in your region. Moreover, you must subscribe to the feature before you can use it.

How do I delete voicemails on my iPhone?
