Is your iPhone going to voicemail if you don’t answer a call but won’t send notifications or leave a message in your voicemail box? Or have you tried to set up a voicemail password and greeting but instead get the message, “Voicemail Unavailable, could not authorize access.”? Your iPhone voicemail isn’t working, and it may be due to an iOS update or poor network connectivity. Luckily, below are easy fixes to the issue. Let’s get right into it.
Method 1. Empty Your Voicemail Box
