The phone is indispensable in our daily life. So, if you receive the voice message "the wireless customer is not available," you may feel worried. In this post, MiniTool Partition Wizard provides the reasons why this issue occurs and solutions for you to fix this issue.

Why the Wireless Customer Is Not Available?

Mobile phones can help us keep in touch with important people in real time. No matter where you are, you can contact other people easily by dialing their phone numbers.

However, you may also have received a voice message “the wireless customer you are calling is not available” when you call someone.

Why do you receive this kind of voice message? Here’re the reasons:

  • The person’s phone that you called is off. One situation is a phone off caused by no battery. The other is the person’s phone being off intentionally.
  • The phone’s battery is loose. (This usually occurs on an old phone model with a removable battery.)
  • You’ve been blocked.
  • The person you’re trying to call is in an area with no network coverage.
