PHONE IS NOT ABLE TO SIGN IN TO INTERNET

Been trying for 3 days to use my Smart Home App on my phone (Galaxy S21 5G)--every time I sign in I get: UNABLE TO SIGN IN Uh.Oh. You need AT&T Internet Service to sign in. If you are an AT&T internet customer, you may need to sign in with a different user ID or link you account to your User ID. (403.400)...what does this mean??? I have both my phone and internet through AT&T and was working jsut fine...now I cannot use it?  And I am also having issues with my phone staying on and keeping internet service--it is dragging and buffering all the time--HELP????

We're here to help with your Smart Home Manager app, @sdillenschneider!

 

Have you attempted to reset the password to your account? Going this can resync your account and correct any errors. 

 

Give this and try and let us know if it helps!

No--I already reset the password online (instead of my phone-since it states that I may need to sign in with a different user ID or link your account.  Waht am I supposed to Link my account to--I only have one account.  AT&T for my  phone and my internet and our TV-UVerse...having problems with the DVR systems as well....not doing well overall with AT&T....was hoping it would be better than Sprint but not yet..... :(

Hi there, sdillenschneider! Let's break this down even further. 

 

Ok, after looking at the current interactions, we may not be asking the right questions. So let's look at this from a different angle.

  • Is you cell phone connected to the same Wi-Fi network that is being broadcasted by your AT&T equipment? The reason why we are asking this, is that for your phone needs to be running off the Wi-Fi instead of a carrier data connection. 
  • Are you able to replicate the problem that you are having on another device, such as another phone or tablet? The reason for this question is, that mirroring the problem can determine if the problem is account or device related. 

So in troubleshooting, let's step away from the app for just a moment. 

 

The Smart Home Manager app has a direct site that we can look at. By using the aforementioned link, you will be directed to log into your account by using your AT&T username and password. Test your information on that site. Please be very careful as, if you try to many times with the incorrect information, you can lock the account out and you will have to wait a full 24 hours before attempting to log in again. 

 

Here is a tip for you. Most AT&T usernames are full email addresses. If you are unable to remember the username, you can use the "Forgot User ID" link you can send yourself an email, to the contact email address on file, with your AT&T user id. 

 

Try these tips and tricks and let us know if they set you up for a successful log-in. 

 

Thank you for reaching out to the AT&T Community Forums.
