Turning on airplane mode on your iPhone disables all wireless connections, including cellular data and Wi-Fi, which can help force a sync between your iPhone and your carrier’s voicemail server, allowing you to delete voicemails that weren’t previously deleted due to syncing issues.

By turning off airplane mode, your iPhone re-establishes its connection to the carrier’s voicemail server, which should resolve the “Voicemail is Full” error message on your iPhone.

Fix 3 – Check Messages and Change Voicemail Password

One effective method to fix the voicemail full error on an iPhone is to check messages and change the voicemail password.

  • To do this, first, go to Settings and select Phone.
  • Then, choose the option “Change Voicemail Password” and enter your new PIN twice.
  • After this, return to the Home screen and dial your voicemail.
  • When prompted for your voicemail PIN, simply hang up without entering anything.
  • Check to see if the problem still persists.

Some users may need to enter their new password to access their voicemail. The service will then notify you that your voicemail is full.

Hang up, wait for thirty seconds, and then dial again. Experiment with both options to find the best solution. This approach can help to clear up any voicemail full errors on your iPhone.

Fix 4 – Delete Voicemails from Mobile Carrier

Even if you’ve deleted all your voicemails from the Phone app, your iPhone may still say voicemail is full.

This means that the voicemails are stored directly on your cell phone carrier server, and your iPhone only downloads and stores them for your convenience.

Your cell phone carrier provides limited storage capacity for your voicemails, so you need to delete them from there.

The steps will be different depending on your cell phone carrier. Here are the instructions for the four major US carriers:

  • Verizon – To retrieve and delete your voicemails, dial *86 on your phone. If you’re calling from another number, call your phone number and press # to cut through the greetings. Follow the prompts to access and delete your messages.
  • AT&T – Press and hold 1 to access your voicemail. When prompted, enter your password. If you are using a different phone, dial the 10-digit mobile phone number. When you reach the voicemail system greeting, press the Star key (*), and then enter your password to log into your voicemail account. Listen to your messages; then erase them.
  • T-Mobile – Call your own number or long-press 1 or dial 123 on your dialer to access your voicemail. Alternatively, call 1-805-637-7249, enter your 10-digit number. When you hear the voicemail greeting message, press the star key (*) and enter your password. Then, use the appropriate keypad number to delete your voicemails.
  • Sprint – Call your phone number or long-press 1, wait until the call goes to voicemail. When the greeting message starts playing, press the star key (*), then enter your passcode. From there, you can listen and delete your voicemails.
