Set up Advanced Messaging

Make sure you and the person you’re messaging are both in our owned and operated domestic coverage area and have:

• AT&T postpaid wireless accounts with HD Voice (not available for AT&T PREPAID^SM)
• Android smartphones that support Advanced Messaging¹ from AT&T
• Advanced Messaging turned on
• Up-to-date software installed on your smartphone
  

Good to know: If you’ve blocked your line’s text or data, Advanced Messaging won’t work. Be sure to disable any blocks to use this feature. Have an unlocked device? Find out if it’ll accommodate Advanced Messaging (PDF, 150KB)

Advanced Messaging varies by smartphone and software version of both the sender and the recipient. The newest version of Advanced Messaging, RCS Universal Profile (UP) 1.0, is available for a growing list of popular smartphones. Look for more phones to be added in the future.
