Old voicemails pile up quickly, and the day a new one fails to arrive is usually the day you notice. How to delete voicemail on iPhone is easy once you know there are really three jobs: removing messages you received, changing the greeting callers hear, and dealing with a message you already left on someone else’s phone.
Our guide covers where voicemail is stored, the steps in the Phone app, the greeting, sent messages, and what to do when the mailbox stays full.
1. Where iPhone Voicemail Is Stored Before You Delete It?
With Visual Voicemail, messages appear in the Phone app, although the voicemail service itself depends on your carrier and region. This distinction matters for how to delete voicemail on iPhone, since removing a message from the visible list may not erase it immediately.
When you delete a voicemail, it can move to Deleted Messages, where it may remain until permanently cleared.
How long deleted messages remain available can depend on your carrier. Voicemail behavior may also change when you switch carriers, SIMs, or voicemail services, so save any important messages before making account or service changes.
2. How to Delete Voicemail on iPhone From the Phone App?

Delete One Voicemail
- Open the Phone app and tap Voicemail.
- Tap the message you want to remove.
- Tap the Delete (trash) button.
The message disappears from your list and moves to the Deleted Messages folder.

3. How to Delete Your Voicemail Greeting on iPhone?
An iPhone has no button that deletes a greeting outright, so how to delete your voicemail greeting on iPhone really means replacing it. You either go back to the standard greeting or record a new one. Greeting options depend on your carrier and region.
Switch Back to the Default Greeting
- Open the Phone app and tap Voicemail.
- Tap Greeting.
- Tap Default.
Callers then hear the standard greeting instead of your recording. Use this when you want your own message gone without recording a replacement.
Record a New Custom Greeting
- Open Voicemail and tap Greeting.
- Tap Custom, then tap Record.
- Speak your message, then tap Stop.
- Tap Play to check it, then tap Save.
Keep it short and include your name, so callers know they reached the right person. If the Default option does not stick, the setting may be controlled by your carrier.
4. Can You Delete a Sent Voicemail on iPhone?
How to delete sent voicemail on iPhone has a short and honest answer: you cannot. A voicemail you leave is stored on the recipient’s mailbox, which your iPhone cannot reach. Once the call ends, the message is delivered.
Some carriers let you re-record or discard a message while you are still on the line, so listen to the prompts after the beep.
Because how to delete voicemail on iPhone only works on your own mailbox, these options help once you have hung up:
- Leave a follow-up voicemail: Say you left the message by mistake and ask the person to disregard it.
- Send a text: A short note often reaches them before they listen.
- Ask them to delete it: They are the only one who can remove it from their mailbox.
5. Why Voicemails Will Not Delete or the Mailbox Stays Full
If you followed how to delete voicemail on iPhone and the mailbox still reports full, one of these usually explains it:
- Deleted Messages was never cleared: The deleted messages still count. Open Deleted Messages and tap Clear All.
- The carrier mailbox is separate: Voicemail is managed by the carrier, so clearing the phone may not free the carrier’s copy. Contact your carrier if the mailbox stays full.
- A SIM change or carrier cleanup: Messages can disappear after a SIM change or when the carrier erases deleted ones. If something is missing, check with the carrier.

6. FAQs
Can I get back a voicemail I deleted?
Yes, if you have not cleared it. Open Voicemail, tap Deleted Messages, select the message, and tap Undelete. After Clear All it is gone from the phone. In some regions the carrier may also erase deleted messages, so restore anything you need soon.
Does deleting a voicemail on my iPhone also clear my carrier’s mailbox?
Not always. Voicemail is managed by the carrier, so a full mailbox can persist after you delete messages on the phone. Clearing Deleted Messages is the step that matters, and if the mailbox still reports full, your carrier can check its side. This is also part of how to delete voicemail on iPhone when space is the real problem.
Can I remove my custom greeting without recording a new one?
Yes. Open Voicemail, tap Greeting, and tap Default. Callers then hear the standard greeting. You can return to Custom and record a new message later, and the options you see depend on your carrier.
Final Thoughts
For messages you received, delete them in the Phone app, then open Deleted Messages and tap Clear All. For the greeting, switch to Default or record a new Custom one. A voicemail you already left cannot be removed, so follow up with the person. You are finished when Deleted Messages is empty and the mailbox no longer reports full. If it does, contact your carrier.
With those steps, how to delete voicemail on iPhone takes only a few minutes.
