Voicemail is a handy feature that allows you to receive voice messages from callers when you’re unable to answer the phone. It’s like an answering machine for your smartphone, providing a convenient way to stay connected and never miss important calls.

When it comes to Samsung Galaxy Z Flip 4, users have reported that they experience voicemail issues, which can be frustrating when expecting important messages. Causes of this issue include incorrect settings, software glitches, or network provider issues. 

This guide offers six (6) comprehensive solutions to fix the voicemail not working issue. Whether you just started using the device or are a pro, these step-by-step instructions will help troubleshoot and resolve the issue.

Fix 01: Activate the Voicemail Service First

Before moving on to more serious solutions, the simplest solution is to ensure that you have activated the voicemail service. Even if you’ve previously enabled this feature, it’s worth checking to make sure it’s still active, as settings can sometimes change without your knowledge. This is particularly true after software updates or when switching network providers.

By doing this, you can see if voicemail is activated:

  1. Open the Phone app on your Samsung Galaxy Z Flip 4.
  2. Tap on the Keypad at the bottom of the screen.
  3. Dial *#61# and press the “Call” button.

  1. If you see a message saying Voicemail Forwarding When Unanswered is Enabled this means your voicemail service is active.

If your voicemail service is not activated, follow these steps to enable it:

  1. Open the Phone app.
  2. Tap on the Keypad at the bottom of the screen.
  3. Dial 61123**30# and press the “Call” button. This code is for activating voicemail service, with 123 being the voicemail number and 30 being the delay time in seconds before the call is forwarded to voicemail.

  1. You should receive a confirmation message saying “Voicemail Forwarding When Unanswered is Enabled”.

Try receiving a voicemail after making sure your voicemail service is operational to determine whether the issue has been fixed.

Fix 02: Force Stop and Clear the Cache of the Visual Voicemail Service

Visual Voicemail is a service that allows you to listen to your voicemails without having to dial into your voicemail inbox. It displays your voicemails in a list, much like emails, so you can choose which ones to listen to and in what order.

Over time, this service accumulates temporary files, known as cache, leading to glitches and issues. Clearing the cache can resolve these issues by removing temporary files and starting the service fresh.

Force stopping and clearing the cache of Visual Voicemail service can be done by going through the following steps:

  1. Open the “Settings” app on your Samsung Galaxy Z Flip 4.
  2. Scroll down and tap on “Apps”.

 Fix 03: Set Up Call Forwarding

Call forwarding is a crucial telecommunication feature that redirects incoming calls to another destination, especially in voicemail services. It ensures that calls are forwarded to the system when the caller is unable to answer.

If call forwarding is not set up correctly, your voicemail might not work as expected. Therefore, appropriately configuring call forwarding might aid in resolving the voicemail not working issue on your device.

Here are the steps to set up call forwarding:

  1. Open the “Phone” app on your Samsung Galaxy Z Flip 4.
  2. Tap on the “Keypad” at the bottom of the screen.
  3. Enter “*#21#“ and press the “Call “ button. This will display the current call forwarding status for all voice calls.

  1. If call forwarding is disabled, you can enable it by going back to the “Keypad” and entering “*21*1#” and then pressing the “Call “ button.

  1. To set up call forwarding to voicemail, go back to the “Keypad” and enter “*21*YOUR VOICEMAIL NUMBER#” and press the “Call” button. Replace “YOUR VOICEMAIL NUMBER” with the actual number provided by your network provider.

Try leaving a voicemail to your number from another device after setting up call forwarding to see if the issue is fixed.

Fix 04: Reset Network Settings

Correct network settings are a must for the smooth functioning of the voicemail service on your Samsung Galaxy Z Flip 4. Your voicemail will not be functioning if these settings are wrong or have been altered.

The “Reset Network Settings” option on your device restores all network settings, including Wi-Fi, mobile data, and Bluetooth, back to their factory defaults. By doing this, any improper settings that cause the root of the issue are removed, and ideally, your voicemail service will once again function.

Here is how you can reset network settings:

  1. Open Settings.
  2. Tap on General management.

  1. Confirm.

Please note that this action will erase all network settings on your device, including saved Wi-Fi networks and Bluetooth pairings. Make sure you have these details saved somewhere else if you need them.

Fix 05: Contact the Network Provider

In some cases, the problem with your voicemail service might not be with your Samsung Galaxy Z Flip 4, but rather with your network provider. The network provider is responsible for transmitting your calls and messages, including voicemails. If there’s an issue on their end, it could prevent you from receiving voicemails.

For instance, your voicemail service should have unintentionally been turned off on their system, or there should be a network outage in your region. You must contact the network provider’s customer service.

Fix 06: Do a Software Update

Updating Samsung Galaxy Z Flip 4 software can resolve voicemail issues by introducing new features and fixing bugs, addressing potential issues and ensuring smoother device performance.

If you haven’t updated the device in a long time, do it as follows:

  1. Head over to Settings.
  2. Tap on Battery and device care.
