Hello
Are you trying to locate your phone records at MyAT&T online access? Once logged in (Site Link), click on "Billing, Usage and Payments" on the top of the page, then select a "Usage" tab. Scroll down to Basic Usage details and you will see the number of text and minutes, as well as data used, for each line. If you click on the number for minutes you will see the full phone calls log. You can do the same for text messages. In there you'll be able to change your billing dates, sort order and even download the logs to your computer.
Please let us know if you have any other questions.
Thanks,
Dmitriy
