If you set up SBCGlobal on your Android phone before 2023, there is a good chance it simply stopped working at some point — probably asking for your password repeatedly or showing authentication errors. This is not an Android problem or a phone problem. AT&T changed how it handles third-party email apps. Your old password no longer works in email apps. An App Password is now required.
This guide covers the fix for existing broken setups and fresh setup from scratch — including Gmail app, Samsung Email and Outlook for Android.
Setting up SBCGlobal email on Android in 2026 is different from how it worked in 2018 and earlier. AT&T now requires an App Password for all third-party email apps — including Android mail apps — and the server settings have changed to AT&T Mail infrastructure. If you set up SBCGlobal on your Android phone years ago and it suddenly stopped working, this guide explains exactly what changed and how to fix it.
What Changed — SBCGlobal on Android in 2026
| What Changed | Before (2018-2022) | Now (2023-2026) |
|---|---|---|
| Password type | Regular AT&T/Yahoo password worked | App Password required — regular password blocked |
| Incoming server | imap.att.yahoo.com or mail.att.net | imap.mail.att.net (updated) |
| Outgoing server | smtp.att.yahoo.com | smtp.mail.att.net (updated) |

| Why it changed | Basic security | AT&T enhanced security — blocks basic auth in apps |

How to Fix Existing Broken SBCGlobal Account on Android
If SBCGlobal was working on your Android before and suddenly stopped — do not delete the account yet. Try this first:
- Go to your email app Settings — find your SBCGlobal account
- Tap the account — find Incoming Settings or Server Settings
- Update the password field with your new App Password
- Do the same for Outgoing Settings
- Save and test by sending a test email
- If still failing — verify server is imap.mail.att.net not an old Yahoo address
- Last resort — delete account and re-add from scratch with correct 2026 settings
Android setup steps verified against Google’s official Gmail IMAP setup guide and AT&T email client configuration documentation. App Password requirement confirmed from AT&T support pages.
First generate an App Password at signin.att.com under Profile — Sign-in info — App passwords. In your Android email app go to Settings — Add Account — Other. Enter your full @sbcglobal.net email and the App Password. Set incoming server to imap.mail.att.net port 993 SSL and outgoing to smtp.mail.att.net port 465 SSL. This works for Gmail app, Samsung Email, Outlook for Android and all other Android email clients.
The most common reason SBCGlobal stopped working on Android is the App Password requirement introduced by AT&T in 2023. Your regular AT&T account password no longer works in third-party email apps. Generate an App Password at signin.att.com under Profile — Sign-in info — Manage app passwords. Update the password in your Android email app account settings. Also verify your server settings are imap.mail.att.net port 993 and smtp.mail.att.net port 465 — old Yahoo server addresses no longer work.
SBCGlobal IMAP settings for Android 2026: incoming server imap.mail.att.net port 993 SSL/TLS encryption authentication required. Outgoing SMTP server smtp.mail.att.net port 465 SSL/TLS authentication required. Username for both is your full @sbcglobal.net email address. Password for both must be an App Password generated at signin.att.com. These replace the older att.yahoo.com server addresses that no longer work.
Open Gmail app — tap the menu — Settings — Add account — Other. Enter your full @sbcglobal.net email and tap Next. Select Personal IMAP. Enter your App Password generated from signin.att.com. Set incoming server to imap.mail.att.net port 993 SSL and outgoing to smtp.mail.att.net port 465 SSL. Tap Next to verify and complete setup. Your SBCGlobal inbox will appear alongside your Gmail in the same app.
An App Password is a separate password generated specifically for third-party apps like Android email clients. AT&T required App Passwords for all third-party email apps starting in 2023 as a security measure. Your regular signin.att.com password only works in a browser — it will not work in Android email apps. Generate an App Password at signin.att.com under Profile — Sign-in info — Manage app passwords. Each device or app should have its own App Password.
Yes. SBCGlobal email works on Samsung phones in 2026 using the Samsung Email app or Gmail app. Open Samsung Email — Settings — Add account — Other. Enter your full @sbcglobal.net email and App Password from signin.att.com. Set server to imap.mail.att.net port 993 SSL for incoming and smtp.mail.att.net port 465 SSL for outgoing. Use Manual setup to enter these settings — auto-detection may not work correctly for SBCGlobal accounts.
If SBCGlobal stopped syncing on Android, first check your internet connection. Then go to your email app account settings and update the password to an App Password generated at signin.att.com. Check that your sync frequency is not set to Manual — change it to every 15 minutes. Verify server settings are imap.mail.att.net port 993. If still not syncing, delete the account and re-add it with fresh App Password and 2026 server settings.
Yes. Open Chrome browser on your Android phone and go to signin.att.com. Sign in with your full @sbcglobal.net email and your regular AT&T password — not an App Password, as browser login uses your regular password. Tap the Mail icon to access your inbox. For easier access, tap the three dots menu in Chrome — Add to Home screen — this creates a shortcut on your Android home screen for one-tap access to your SBCGlobal inbox without any app setup.
