Today I went to this site. It refused to take my phone number ID or email ID. I have had the same phone number since 1984. It refused my password although I tried to enter it three different ways because over time I have had more than one service with AT&T. That 'time' would be since 1967. It showed me a bill for a phone # I haven't had since 2011. It showed me a bill from 2018. So I'm not wild about this app. Usually, if I want to access my bill, I use Google because this app sucks.
