| What Is... | Signing In to Chat | Sending a Text Message | Switching Between Texting, Chat, and Email |
Your online chat availability determines whether you can send text messages to your contacts. If you’re signed in to AT&T Mail’s chat feature (that is, online), you can initiate text messaging; if you’re signed out of chat (offline), you can’t.
If you’re signed out of chat, you’ll see a gray circle (
) and "Offline" next to your name at the top of the Mail page.

Just sign in to get started text messaging.
Tip: For text messaging, it doesn’t matter what your online status is, as long as you’re signed in. You can be available (
), busy (
), or even invisible (
) and still be able to send and receive text messages. See the Chatting With Your Contacts tutorial to learn more about different chat statuses and how to create your own status messages.
