Hello, @chamblissfarm! We want to help you log in to your wireless AT&T account.

To start, based on the information provided, it sounds like you may be trying to sign in using the incorrect User ID, which is why the website keeps bouncing you back and forth. We recommend making sure your User ID is properly linked to your accounts. Please check the link here: https://www.att.com/support/article/my-account/KM1008925

How exactly are you trying to sign in to your AT&T account? We ask, as we have a few troubleshooting steps to help you get into the right account:

• If you're trying to sign in to your account using a browser, try clearing your cache and cookies, mentioned in the link here: https://www.att.com/support/article/u-verse-high-speed-internet/KM1010153/. This just may be a website glitch, which can be quickly fixed just by clearing your browser's cache and cookies, or even using a different browser.
• If you haven't done so already, try signing in through the MyAT&T app here: https://www.att.com/support/article/my-account/KM1066068/. This will help us narrow down the source of the issue, such as if this is the website or your login information.

Please let us know if this helps, so we can look into this further if needed.
