Hi, thank you for contacting JustAnswer.com. My name is Russell. I will do my best to provide the right answer to your question.
I think that, if your password ***** wrong might be the issue, or the device not being authorized to work or to deliver internet might be the issue, you would do well to call ATT support about it, just to do some basic checks on the matter.
If you find it really is nothing more nor less than the password, then you should have ATT Support reset it for you, then change it - carefully! - to your preference of passwords.
Let me know if that sounds right, if you need further information, etc. I'm ready to help.
The amount of time you have spent online with JustAnswer (that I can see) is only 7 minutes so far, or perhaps 10 minutes.
I am sorry to see that other efforts have used up so much time.
Will you need the ATT Customer Support number?
