Unable to sign in using MyAT&T app Care code: 600
For the last few days, whenever I attempt to use the MyAT&T app I am unable to login. I open the app, select sign in, select my user id, it buffers for quite a while, then I receive a pop-up message saying, “Hmm, looks like there’s an issue with either the network connection or the server. Try signing in again later. Care Code: 600.” I have reinstalled the app, turned my phone off/on, checked for both app and iPhone updates and both are up to date, and I’ve tried multiple wifi networks and cellular connections with none of these working to resolve the issue. I’m able to log in using a browser with no problems whatsoever. Please advise as this is incredibly annoying. I thought having to sign in multiple times per session was annoying…

Thank you for letting us know what troubleshooting steps you have already attempted. The error code 600 simply means that there isn't a network connection, we recommend signing in later.

This is unacceptable to just “try again later” I am having the exact same issue all day long. Except when I try to log in via a web browser ATT says that I don’t even have an internet account. That’s strange since I just signed up and haven’t even had the service for 30 days. How about y’all keep you servers running? I think 6 hours is enough time for someone to figure out the problem.

@tomresz Your issue doesn't sound like it's anything wrong with "servers." Have you created your online account yet? Are you able to access your account through the app?
