You’re staring at your screen, waiting for that little red dot to tell you someone actually left a message. Then it happens. You tap the greeting, and suddenly, iOS demands a PIN you haven't thought about since the Obama administration. It’s annoying. Most of us set these codes when we first unbox the phone and then let them rot in the back of our brains because, let’s be honest, FaceID usually handles the heavy lifting. But knowing how to change voicemail password on iphone is one of those "boring but essential" tech skills that saves you from a total communication lockout when the network glitches.
Modern iPhones are smart, but the voicemail system is actually a weird hybrid. It’s half Apple software and half carrier infrastructure (think Verizon, AT&T, or T-Mobile). Because of this split personality, there isn't just one way to fix a forgotten password. Sometimes the Settings app works like a charm. Other times, you have to go "old school" and call a robot.
The Settings Method: The Path of Least Resistance
If your phone is behaving, you can handle this in about twenty seconds. You don't need to call anyone. You don't need your old password (usually). Open up that grey Settings icon. Scroll down past the big hitters like Notifications and Screen Time until you find Phone. It’s usually tucked between FaceTime and Messages.
Once you’re in the Phone menu, look toward the bottom. You’ll see a button labeled Change Voicemail Password. Tap it. Your iPhone will prompt you to enter a new PIN. This needs to be between four and fifteen digits. Pro tip: Don't use "1234" or your birth year. Carriers have gotten surprisingly picky about "weak" passwords lately, and they might reject a sequence that's too obvious. After you type it once, you’ll have to type it again to confirm. Hit "Done" in the top right corner.

If that button is greyed out or just plain missing, don't panic. You aren't crazy. This usually happens because your carrier hasn't "pushed" the visual voicemail credentials to your device correctly, or you’re currently in a dead zone. Sometimes a simple toggle of Airplane Mode forces the phone to reconnect to the server and brings that option back to life.
When the Settings App Fails You
Hardware is fickle. Sometimes you tap "Done" and get an error message that says "Voicemail Unavailable" or something equally vague. This is where most people give up and head to the Apple Store, which is a waste of a Saturday. If the on-device method fails, you have to talk to the carrier's automated system directly.
Think of it as bypassing the iPhone's skin and touching the nervous system of the cellular network. Open your Phone app and go to the Keypad. Hold down the 1 key. This is the universal shortcut for calling your voicemail box.
You’ll likely hear an automated voice asking for your password. If you don't know it, don't just keep guessing. Too many wrong attempts will lock your mailbox entirely, and then you’re stuck in "customer service purgatory" on a Friday night. Instead, look for an option to "Change Personal Options" or "Administrative Settings." The prompts vary. For Verizon users, it’s usually option 4, then 2, then 1. T-Mobile users often have to hit the star key (*) during the greeting to get to the main menu.
The Carrier "Secret Codes" Shortcut
If you’re a fan of those hidden features that make you feel like a hacker, you can use MMI codes. These are short strings of numbers and symbols you type into the dialer to talk to the network. They aren't widely advertised because, frankly, carriers would rather you use their bloated apps.
- AT&T: Call 611 from your phone or use the myAT&T app. They actually removed many of the manual dialer overrides for security reasons.
- T-Mobile: Dial #PWD# (that's #793#) and press call. This resets your voicemail password to the last four digits of your phone number. It’s a lifesaver.
- Verizon: You can dial *611 and say "Reset voicemail password" to the robot. It’s surprisingly effective.
Why Does My iPhone Keep Asking for My Password?
There is this specific, localized hell where your iPhone asks for your voicemail password every single time you open the app. It's maddening. You enter it, it goes away, and then ten minutes later—pop—it’s back.

This usually isn't a password problem. It’s a synchronization error. Your iPhone is trying to "check in" with the carrier’s server to download new messages, but the "handshake" is failing.
Try this: Go to Settings > General > Transfer or Reset iPhone > Reset > Reset Network Settings.
Warning: This will wipe out your saved Wi-Fi passwords. You'll have to log back into your home internet. However, it forces the iPhone to rebuild its relationship with the cell towers from scratch. Nine times out of ten, this stops the constant password prompts. It’s like a forced therapy session for your antenna.
Dealing with Visual Voicemail Glitches
Visual Voicemail is that fancy list where you can see who called and read a transcript without listening to the audio. It’s great when it works. When it doesn't, it’s often because your Cellular Data is turned off.
Voicemail data doesn't travel over Wi-Fi in the same way your iMessages do. It needs a cellular handshake. If you’re traveling abroad or you’ve turned off data to save money, you might find that you can't change your password or even access your inbox. Make sure you see "LTE," "4G," or "5G" at the top of your screen before you try to fiddle with the settings.
Security and the "Stupid Password" Problem
We all use the same five passwords for everything. We shouldn't, but we do. However, your voicemail PIN is surprisingly vulnerable to "spoofing." In the early 2010s, there were several high-profile scandals involving people hacking into voicemails just by guessing 0000 or 1234.
When you change voicemail password on iphone, pick something random. Don't use the last four of your SSN. Don't use your address. Use something that has no connection to your public identity. Also, keep in mind that if you ever swap SIM cards or move your eSIM to a new iPhone, you’ll probably have to re-enter this password. Write it down in a secure note or a password manager like Bitwarden or 1Password.
What if I'm on a Prepaid Plan?
Prepaid carriers like Mint Mobile, Cricket, or Visible handle things a bit differently. They often use the "parent" network's infrastructure but have their own proprietary apps. If you're on Mint, for example, the iPhone settings menu might not always work perfectly.
In these cases, your best bet is the carrier's specific app. Log in, go to "Account" or "Plan Settings," and look for a "Reset Voicemail PIN" option. They’ll usually text you a temporary code.
Troubleshooting the "Saving Password" Infinite Loop
Sometimes you enter the new password, the little loading wheel spins forever, and then... nothing. The old password remains. This is common if your iPhone's software is out of date. Apple occasionally updates the carrier settings—literally called "Carrier Settings Updates"—independently of the main iOS updates.
Go to Settings > General > About. Stay on that screen for about 30 seconds. If an update is available, a pop-up will appear out of nowhere asking if you want to update your carrier settings. Tap "Update." This often fixes the backend communication issues that prevent password changes.
Moving Forward: Your Action Plan
Don't let a locked voicemail box prevent you from hearing that important call from the doctor or your boss. If you've been putting this off, take five minutes right now to get it sorted.

- Try the easy way first: Go to Settings > Phone > Change Voicemail Password.
- Use the "Force" method: If Settings fails, dial 1 on your keypad and follow the voice prompts to the "Administrative" or "Personal Options" menu.
- Reset the Network: If you’re getting constant, annoying pop-ups, use the "Reset Network Settings" option in your General settings.
- Update Carrier Settings: Check the "About" section of your phone to see if a carrier update is pending.
- Record the PIN: Store the new number in a password manager immediately so you don't have to do this again in 2027.
If none of these steps work, it’s a high probability that your account has a "feature block" at the carrier level. This happens sometimes during plan migrations. At that point, you’ll need to contact your carrier’s technical support department and ask them to "re-provision" your visual voicemail service. It sounds technical, but it basically just means "turn it off and back on again" at the server level. Once they do that, the standard iPhone settings will suddenly start working again.
