Combine your AT&T wireless and Unified Messaging voicemail boxes

Add your AT&T wireless number to your Unified Messaging voicemail box and receive voicemail messages for both in one voicemail box.

Get wireless and home phone messages in a single voicemail box

Before you begin

This service is only available when your wireless service is provided by AT&T and is not a prepaid number. Unified Messaging works with most wireless phones from AT&T, but not all.

Before combining your mailboxes it’s important to be aware of the following:
  • Once combined, your wireless voicemail box will be eliminated and any existing messages will be lost. Review and document any new, existing, or saved messages in your wireless voicemail. 
  • Messages won’t transfer to your Unified Messaging mailbox.
  • Both services must originate within the same service area, or the combined mailbox may not work properly and you may incur additional charges. 
  • If your wireless device has visual voicemail, the email-like inbox will no longer receive new messages. 

When your mailboxes are combined, the greeting on your home phone mailbox becomes the greeting for both home phone and wireless. To create a different greeting for when your wireless number is called, press and hold the 1 key on your wireless phone. Follow the directions to record your greeting. Your home phone greeting will not be changed.
