Troubleshooting Tips for iPhone Voicemail
Check Your Signal Strength
If your iPhone voicemail is not working, the first thing you'll want to check is your signal strength. A cellular data network connection is needed to access your voicemail. If your signal strength is low or not connected, it may be why your voicemail isn't working. To check your signal strength, look to see how many signal bars are displayed at the top left corner of the screen. If the signal is low, try checking your voicemail again when you have stronger signal. If you have no signal, you'll want to make sure airplane mode is turned off.
Verify iPhone Voicemail Setup
Make sure that iPhone's Visual Voicemail has been set up. You can find it in the "Phone" application. The last icon to the right across the bottom of the screen is the visual voicemail feature.
The first time the visual voicemail feature is accessed, you will be prompted to create a password and record a greeting. If you are unable to setup iPhone voicemail, contact your carrier to make sure that they offer the feature. They will also be able to help you determine if the voicemail has been configured properly.
Dealing with Voicemail Password Issues
Forgot your voicemail password? Or are you receiving a "Password Incorrect" notification? Password incorrect for iPhone voicemail can be addressed by contacting your wireless carrier for assistance.
Reset iPhone Network Settings
If you've tried all the options above and iPhone voicemail isn't working, try resetting the network settings. This will clear your current cellular and Wi-Fi network settings. To reset network settings, go to "Settings", then "General". Once inside the General settings menu, scroll all the way to the bottom and select "Reset". Then select "Reset Network Settings."
