Voicemail is basically a digital fossil. Honestly, unless you're a real estate agent or a doctor, getting a notification that you have a new message is usually just a chore. Most of us just want to take voicemail off iPhone for good. But here is the thing: Apple doesn't actually give you a big red "Off" switch in the Settings app. It’s annoying. You look through the Phone settings, you check under General, and you find nothing. That's because voicemail isn't actually an iPhone feature; it’s a carrier service that your phone just happens to display.
Why it is so hard to just turn it off
Most people assume the "Phone" app controls everything. It doesn't. Your carrier—think Verizon, AT&T, T-Mobile, or Mint—is the one actually holding your messages hostage on their servers. When someone calls you and you don't pick up, the network diverts that call to a separate server before it even hits your device.
If you want to stop this, you have to talk to the network, not the software.
Sometimes people try to just "mute" it by not setting up the mailbox. Bad move. If you don't set it up, many carriers will just play a generic automated voice telling the caller that "the mailbox has not been initialized." It still wastes the caller's time. It still feels like 1998. To truly take voicemail off iPhone, you need to break the conditional call forwarding chain that links your number to the carrier's deposit system.
The Secret MMI Codes (The Techy Way)
You’ve probably never heard of MMI (Man-Machine Interface) codes. They are these weird strings of characters like #004# that you type into your keypad. Back in the day, this was how engineers tested networks. Today, they are the fastest way to disable your mailbox without waiting on hold for a customer service rep.
For most GSM carriers (like T-Mobile or AT&T), the magic string is ##004#. Open your Phone app, go to the Keypad, type that in, and hit the green call button.
You’ll see a gray screen pop up with some text about "Setting Erasure Succeeded." What you just did was tell the network to stop forwarding calls to the voicemail server when you're busy or don't answer. It’s a clean break. However, this doesn't work for every single carrier. Verizon, for instance, is notorious for blocking these codes because they'd rather you pay for "Premium Visual Voicemail." If you’re on a CDMA-legacy network, those codes might just give you an "Error Performing Request" message.

Calling the Carrier: The Last Resort
If the codes fail, you have to do the one thing we all hate: call support.
Ask for "Technical Support," not billing. Once you get a human, tell them exactly this: "I want to disable my voicemail feature entirely at the system level." Don't let them just "reset" it. Resetting just clears your messages. You want the feature removed from your account provision.
I've seen cases where people had to pretend they were traveling internationally just to get the rep to agree. Apparently, some carrier scripts make it hard for reps to just "delete" a free service. But if you insist that you are using a third-party service or that it’s for privacy reasons, they usually click the button. Once they do, your iPhone will basically just ring and ring, or it will eventually play a "number unavailable" tone. That is the goal. No more red badges. No more "transcription not available" nonsense.
The Problem with Visual Voicemail
Visual Voicemail was a revolution when the original iPhone launched in 2007. Steve Jobs spent a lot of time on it. But now, it’s just a graveyard of spam calls from "Scam Likely." Even if you turn off notifications, the iPhone still downloads the audio data in the background. This uses data. It uses battery.
Some users try to bypass this by using an "empty" greeting. You record five seconds of silence and save it. It’s a clever hack, but it doesn't actually take voicemail off iPhone. It just makes your callers think your phone is broken. Plus, they can still leave a message, and you'll still get that annoying little red dot on your Phone icon that refuses to go away until you listen to the silence.
Third-Party Apps: A Better Alternative?
If you want to keep the ability to see who called but hate the carrier's interface, look into apps like YouMail or NoPlum. These services use "Conditional Call Forwarding" to hijack your missed calls. Instead of going to the carrier, the call goes to their app.
The cool part? YouMail has a "Ditch Mail" feature. It plays a "Number Out of Service" tone to callers you've blacklisted. To the caller, it sounds like your phone is disconnected. To you, it’s just peace and quiet. This is a great middle ground if you are scared of completely deleting your mailbox but want to stop the influx of spam.
What about Live Voicemail in iOS 17 and later?
Apple recently introduced "Live Voicemail." This changes the game a bit. With this turned on, your iPhone handles the recording locally. You see a live transcript as the person is speaking.

If you want to stop using your carrier's old-school system and use Apple's new one, you actually need to keep your carrier voicemail active but let the iPhone intercept it. To manage this:
- Go to Settings.
- Tap Phone.
- Look for Live Voicemail.
- Toggle it Off if you want absolutely nothing to happen when a call is missed.
Keep in mind, if Live Voicemail is off, and your carrier voicemail is still on, the call will just fall back to the carrier's server. It’s a layered system. You have to peel back both layers to get total silence.
A Warning for International Travelers
Be careful. If you successfully disable your voicemail using MMI codes and then fly to another country, your "Call Forwarding" settings might get wonky. Roaming networks sometimes force-enable voicemail to prevent "ghost calls" from looping endlessly. If you’re traveling, it’s often safer to just put your phone in "Do Not Disturb" mode and deal with the messages when you get home rather than messing with the network settings in a foreign land.
Final Steps to Sanity
To make sure your efforts stuck, have a friend call you and let it ring out. If they hear "The person you are calling is unavailable" followed by a hang-up, you’ve won. If they still hear your voice or a beep, the carrier override didn't take.
Actionable Checklist:
- Try the code first: Dial
##004#and see if the network accepts the command. - Check iOS Settings: Ensure "Live Voicemail" is toggled off if you want to prevent the phone from recording locally.
- Contact Support: If the badge persists, tell your carrier to "Remove the Voicemail Provision" from your line.
- Clear the Badge: Sometimes the red dot stays even after the service is dead. To kill it, go to Settings > General > Transfer or Reset iPhone > Reset > Reset Network Settings. You’ll lose your saved Wi-Fi passwords, but that persistent voicemail notification will finally vanish.
Stop letting a 90s technology dictate how you use your $1,000 smartphone. Take control of your dialer and kill the mailbox.
