Hello there, katrinalitty!
Thanks for reaching out to the Apple Support Communities! It sounds like you're having an issue with your voicemail being locked out. Voicemail is a carrier function and, with what you have going on, it would be best to reach out to the carrier you use for further assistance with your voicemail. You'll find additional information about voicemail in this article to Set up Visual Voicemail on your iPhone:
If you can't set up Visual Voicemail, contact your carrier to make sure that your plan supports the feature.
If you need help, try these steps. Check your Visual Voicemail after each step:
- Make sure that you have the latest version of iOS.
- Check for a carrier-bundle update: Go to Settings > General > About. If an update is available, a message will ask you to update.
- To check your cellular network connection, try to call someone.
- Make sure that you set up your voicemail. To check, dial your own phone number from your iPhone and leave yourself a message.
- Call your iPhone from another phone and try to leave yourself a voicemail.
- Go to the keypad and press and hold on the 1, or press the Call Voicemail button. This dials voicemail. Check if you have any missed messages.
- On the Voicemail screen, tap Greeting. Then change your greeting to either custom or default.
- If you have more than one cellular plan on your iPhone, try switching to the other plan. Call the first number and try to leave a message.
- Go to Settings > General > Reset and tap Reset Network Settings.
- If you still need help, contact your carrier."
Cheers!
