Disconnecting a voicemail service is not a universal toggle switch found in a single menu. Because voicemail is a service managed primarily by your mobile carrier's network rather than your phone's hardware, the most reliable and permanent way to disable it is to contact your service provider directly by dialing 611 from your mobile device.

While contacting a representative is the gold standard for removal, there are several secondary methods involving device settings and short codes that can effectively bypass or silence the service.

Contact Your Carrier for Permanent Deactivation

Voicemail exists as a feature on your cellular account. Even if you turn off settings on your iPhone or Android, the carrier’s server will still attempt to intercept unanswered calls and record messages.

To ensure the service is fully removed from the network level:

  1. Call Customer Service: Dial 611 from your phone. This is a free call to your carrier’s support team in most regions.
  2. Request Feature Removal: Speak to a representative and explicitly ask them to "remove the voicemail feature" from your service plan.
  3. Confirm Plan Compatibility: Some bundled plans require a voicemail box to be active. In these cases, ask the representative to set your "ring time" to the maximum duration or to disable "conditional call forwarding" so calls ring indefinitely without hitting a mailbox.

This method is the only way to prevent callers from hearing your greeting or leaving a message once your inbox is officially "disconnected" from the carrier side.

Disable Voicemail via Call Forwarding Settings

Voicemail works through a process called "Conditional Call Forwarding." Your phone is programmed to send a call to a specific carrier number if you don't answer, if your line is busy, or if you are out of reach. Disabling these forwarding rules can stop calls from reaching the voicemail server.

Steps for Android Devices

Android menus vary by manufacturer, but the core settings are generally found within the Phone app:

  1. Open the Phone app.
  2. Tap the three-dot menu (usually in the top right corner).
  3. Select Settings and then navigate to Calling Accounts or Supplementary Services.
  4. Tap on Call Forwarding.
  5. You will see three main options: "Forward when busy," "Forward when unanswered," and "Forward when unreachable."
  6. Select each one and tap Turn Off or Disable.

Note that some carriers "lock" these settings, preventing you from changing them manually. If the options are greyed out, you must use the carrier contact method mentioned above.

Steps for iPhone (iOS)

Apple provides a straightforward toggle for general call forwarding, though it may not catch every "conditional" scenario:

  1. Open the Settings app.
  2. Scroll down and tap Phone.
  3. Select Call Forwarding.
  4. Toggle the switch to Off.

If you still find that calls are going to voicemail after this, it is likely because the carrier’s network-level forwarding is still active, overriding the local device preference.

Turning Off Built-in Smartphone Software Features

Modern smartphones often have local software features that mimic or enhance traditional voicemail. Even if you disconnect your carrier's service, these local features might still prompt callers to leave a message.

Disabling Live Voicemail on iPhone

Introduced in iOS 17, Live Voicemail allows the phone to transcribe messages in real-time on your screen. This is a local device feature, not a carrier feature.

  1. Go to Settings.
  2. Tap on Apps (or search for Phone in older iOS versions).
  3. Tap Phone.
  4. Select Live Voicemail.
  5. Toggle the switch to Off.

Disabling Google Call Screen on Android

Pixel and some other Android devices use "Call Screen" or "Take a Message" features where the Google Assistant answers for you.

  1. Open the Phone app.
  2. Tap the three-dot menu and select Settings.
  3. Tap Spam and Call Screen.
  4. Select Call Screen.
  5. Ensure that the settings are adjusted so the Assistant does not automatically answer or offer to take a message for your calls.

Using MMI and USSD Short Codes

Many carriers allow users to communicate directly with the network using short codes (Man-Machine Interface codes). These can be used to disable call forwarding rules instantly.

To use these, open your phone's dialer, enter the code, and press the "Call" button.

Common Global Deactivation Codes

  • Deactivate all forwarding: ##002# or ##004#. These are universal GSM codes intended to reset all call diversions to the default "off" state.
  • AT&T Specific: Many users report that dialing ##004# successfully disables the forwarding path to the voicemail system.
  • Verizon Specific: Dialing *73 is the standard command to deactivate all call forwarding on the Verizon network. You will usually hear a short tone or a quick message confirming the change.
  • T-Mobile Specific: Similar to AT&T, ##004# is the primary command for cancelling the forwarding rules that lead to voicemail.

Warning on Codes: These codes are highly dependent on your specific network technology (GSM vs. CDMA). While they work for most modern LTE and 5G networks, they may fail or return an "Invalid MMI Code" error on certain prepaid plans or legacy networks. If a code fails, it will not damage your phone, but it simply means the network did not accept the command.

Reasons Why Users Disconnect Voicemail

Understanding why people move away from voicemail helps in deciding if a total disconnect is right for you.

Avoiding Spam and Robocalls

Automated dialers often leave silent or pre-recorded messages in your inbox. Disconnecting the voicemail prevents your storage from filling up with hundreds of "dead air" recordings, which can be a significant administrative burden to clear.

Enhanced Privacy and Security

Voicemail systems are historically vulnerable. If a voicemail box has a weak or default PIN, hackers can sometimes access messages remotely using "social engineering" or by spoofing the owner's phone number. For high-security professionals, removing the possibility of a recorded message reduces the "attack surface" of their personal data.

Preference for Asynchronous Text Communication

In a digital-first environment, many find checking voicemail to be time-consuming compared to reading a text or an email. By disabling voicemail, you force callers to use more efficient channels like SMS, WhatsApp, or Slack, where information is searchable and easier to manage.

Troubleshooting After Disconnecting

Once you have performed the steps to disconnect your voicemail, it is essential to verify that the changes have taken effect.

How to Test Your Setup

  1. Call from another number: Use a landline or a friend's phone to call your number.
  2. Let it ring: Do not answer the call.
  3. Monitor the result:
    • Success: The phone should ring for a long period (usually 30-60 seconds) and then give a signal that the subscriber is unavailable, or simply disconnect without a greeting.
    • Failure: If you hear your recorded voice or a generic "Please leave a message" prompt, the network is still forwarding calls to a mailbox.

Common Mistakes to Avoid

  • Trying to "Fill" the Inbox: Some users try to block new messages by letting their inbox reach capacity. This is ineffective because most carriers automatically purge old messages after 14 to 30 days, which eventually re-opens the box for new spam messages.
  • Relying on "Do Not Disturb": DND mode silences your ringer, but it actually forces calls to voicemail faster because the phone tells the network the line is "busy" or "rejected." If you want to stop voicemail, DND is the opposite of what you should use.
  • Ignoring Third-Party Apps: If you have ever used apps like YouMail or Google Voice, they might have set up their own forwarding rules on your line. You must log into those specific apps to "Deactivate" their service before the carrier settings can return to normal.

Alternatives to Traditional Carrier Voicemail

If your goal is to manage calls better rather than simply silencing them, consider these alternatives:

  • Visual Voicemail: Instead of calling a number and listening to audio, Visual Voicemail (built into iPhone and many Androids) lets you see messages as a list. You can delete them without ever listening to them.
  • Third-Party Call Blockers: Apps can be configured to "pick up and hang up" on known spam numbers, preventing them from ever reaching the stage where they could leave a message.
  • Google Voice: You can port your voicemail to Google Voice, which provides superior transcription and better tools for blocking specific callers while allowing family members to still leave messages.

Summary of Voicemail Disconnection

To stop voicemail from intercepting your calls, follow this priority list:

  1. Direct Carrier Contact: Dial 611 and ask for the "Voicemail Feature" to be removed from your account. This is the only 100% effective method.
  2. Reset Forwarding Rules: Use MMI codes like ##004# (for GSM) or *73 (for Verizon) to tell the network to stop diverting missed calls.
  3. Adjust Device Software: Turn off "Live Voicemail" in iOS settings or "Call Screen" in Android settings to prevent your phone from answering on your behalf.
  4. Verification: Always call your own number from a different device to ensure no greeting or recording prompt remains active.

Frequently Asked Questions

What is the code to turn off voicemail?

For most GSM carriers (like AT&T and T-Mobile), the code is ##004#. For Verizon, the code is *73. These codes must be entered into the phone's keypad followed by the call button.

Can I turn off voicemail on a prepaid phone?

Yes, but prepaid carriers often have more restrictive systems. You may find that the MMI codes do not work. In these cases, you must use the carrier’s mobile app or call their specific support number to request deactivation.

Will turning off voicemail delete my saved messages?

If you ask the carrier to "remove the feature," it will typically delete the entire mailbox along with any saved messages. It is highly recommended to save any important audio files before requesting a total disconnect.

Does disconnecting voicemail cost money?

No, disabling a feature typically does not incur a fee. In fact, some international travelers disable voicemail specifically to avoid "roaming" charges that occur when a call is diverted to a mailbox while they are abroad.

Can I re-enable voicemail later?

Absolutely. You can call your carrier (611) at any time to have the voicemail feature added back to your plan. You will likely need to set up your greeting and PIN from scratch as if it were a new account.

Why is my phone still going to voicemail after I turned it off?

This usually happens because "Conditional Call Forwarding" is still active at the network level. Even if your phone is "off," the carrier's computer knows to send the call to the voicemail server. You must ensure the carrier has truly disabled the feature or that you have successfully run the reset codes.

Is there a way to stop voicemail without calling the carrier?

You can try the ##004# code or manually disabling call forwarding in your phone's "Supplementary Services" menu. However, if the carrier has these settings "hard-coded" into your SIM profile, a phone call to support is the only remaining option.
