iPhone Voicemail Full? Here’s The Real Fix!

Voicemail is full on your iPhone and you’re not sure why. The voicemail menu is empty in the Phone app, but your inbox is still full. In this article, I’ll explain why your iPhone voicemail is full and show you how to fix the problem!

Why Is My Voicemail Full?

Most of the time, your iPhone voicemail is full because the voicemails you deleted on your iPhone are still being stored somewhere else. Most of the time, those voicemails are still being stored with your carrier.

Call into your voicemail on your iPhone and play your voicemails. At the end of each voicemail, press the number designated for deleting voicemails. This will erase the messages saved by your carrier and free up space in your voicemail inbox.

If your voicemail is still full, follow the step-by-step guide below!

How To Delete Voicemail On Your iPhone

If you haven’t already, delete the voicemails currently stored on your iPhone. To do this, open Phone and tap Voicemail. Then, tap Edit in the upper right-hand corner of the screen. Tap on the voicemails you’d like to delete.

Tap Delete in the lower right-hand corner of the screen when you’ve selected all the voicemails you’d like to erase.

Clear All Deleted Messages

Even when you delete a voicemail on your iPhone, it’s not necessarily erased entirely. Your iPhone saves your recently deleted messages, just in case you’ve made a mistake and erased an important one. However, this means a lot of deleted messages can pile up and fill your voicemail inbox.

Open Phone and tap on the Voicemail icon in the lower right-hand corner of the screen. Scroll down and tap Deleted Messages. Tap Clear All in the upper right-hand corner of the screen. Tap Clear All again to permanently erase your deleted messages.

Clear All Blocked Voicemails

Voicemails from blocked numbers can take up space in your inbox too. Many iPhone users don’t realize that blocked numbers can still leave messages. These types of messages won’t show up in your list of voicemails, but they can still take up space without you knowing it!

To delete block messages, open Phone and tap Voicemail. Tap on Blocked Messages, then delete the ones you don’t want.

Contact Your Wireless Carrier

If your voicemail inbox is still full, it’s time to contact your wireless carrier for help. You may need to call in and reset your mailbox.

Here are the customer support numbers for the top 4 wireless carriers:

  • Verizon: 1-800-922-0204
  • AT&T: 1-800-331-0500
  • T-Mobile: 1-800-937-8997
  • Sprint: (888) 211-4727

Just let them know that your iPhone voicemail is full and they’ll help you fix the problem!

My iPhone X has a full voicemail box when someone tries to leave a message but I can’t find any voicemails to delete. There is no Edit button on the top right corner of the screen. I’ve reset the phone and upgraded to iOS 15. What shall I do?

Sorry, take out the “didn’t receive” part. My phone often types words that I don’t say or think even. LOL, it can get me in a lot of trouble. Thank you.

How do I restore, as in Save? I didn’t receive a voicemail that’s on the deleted list?

Hi Michael! To clear out space in your Voicemail inbox, open the Phone app and tap Voicemail. Then, tap Edit in the top-right corner. Then, tap the circle next to any voicemail you would like to delete. Once you’ve selected every voicemail you would like to get rid of, tap Delete in the bottom-right corner and that should free up some storage in your Voicemail. Hope this helps!

You should reach out to your cell phone carrier to see if they can help you recover your voicemail password. I hope this helps! ?

It’s amazing and frustrating that such a simple issue requires such a convoluted process. 1970s tape-based answering machines called and what their problem back. Is there really no way to get notified that your voicemail is full or close to full? Not even a way to see how full your voicemail is? It’s a problem that could easily be solved if Apple and/or wireless companies gave a hoot.

Can confirm that this issue has frustrated me from time to time. It’s up the mobile networks to sort that issue out, as Apple only is responsible with the hardware and software of the phones themselves. Fortunately this issue isn’t debilitating, but that’s probably the reason why they are dragging their feet to provide a solution ?

What about the issue of not getting warnings of how full your voicemail is? I don’t get warnings any more that tells me it’s 90% or more full. I don’t know it’s full until someone tells me.

This may depend on your carrier. Try reaching out to your carrier to see if they know what’s wrong
