Several users are reporting this voice mail problem. It seems that iPhone 18 Pro displays a warning message saying voicemail is 95% or 100% full, even though there are no voicemail messages or there are just a few messages.
Are you also getting voicemail full notifications on your iPhone 18 Pro and deleting messages are not solving the problem? Then this article is for you.
Please try each step below until your issue is resolved:
Before you do anything, make sure that your iPhone is running the latest version of iOS.
- Go to Settings.
- Tap General.
- Tap Software Update. The currently installed version of iOS is shown, and whether an update is available.
1– Please make sure that you deleted voicemails completely. I say this because when you delete a message it’s removed from the visual voicemail list (looks deleted) but they are not really deleted. To see your voicemail messages, go to the Phone app. In the Unified layout, tap Calls, tap the Filter button, then tap Voicemails. In the Classic layout, tap Voicemail. In some countries or regions, deleted messages may be permanently erased by your carrier. And then check to see if you are still getting this warning messages. Before deleting messages, make sure that your wireless coverage signal is strong enough for your voicemail services to work.
2– If you still have this problem, now turn on Airplane Mode on your iPhone (Settings > Airplane Mode) and then delete the voicemails. And now turn off Airplane Mode.
3– On your iPhone, tap Settings > Apps > Phone and then tap Change Voicemail Password and change your password. Then Call Voicemail (dial *86 for Verizon for example) and before entering your password just hang up. And now check to see if your problem is resolved. Please note that there is no way to reset this password on your iPhone if you forget it. If you forget, you need to call your cellular carrier.
4- Carrier settings updates let your carrier provide updated carrier network and settings. To check, go to Settings > General > About. If there is an update, you will see a message. Follow the onscreen instructions to install your carrier update. If you do not see the update message, then go to the next step.
5– Reset network settings. On your phone, go to Settings > General > Transfer or Reset iPhone > Reset and tap Reset Network Settings. Please note that this action will erase your network settings like Wi-Fi settings and passwords etc.
6– On your iPhone, if you turned on Call Forwarding, turn it off and on again. Go to Settings > Apps > Phone > Call Forwarding.
If nothing above helps you, you may want to contact your cellular network provider (Verizon, AT&T, T-Mobile etc). Messages are saved until you delete them, or until your carrier erases them if they’re not stored in iCloud.
