Call history for a discontinued cell number

Question

I changed service provider on one of our cell phones last year so that number no longer appears in my ATT account. How can I access the call history on that number while it was serviced by ATT?

I will answer my own question in case any ever needs to know.

If you still have online access to the AT&T account, you can obtain usage information for the prior 18 months. These can be downloaded as 'csv' or 'Excel' files. Information older than that must use the method described in the next paragraph.

From talking with customer service, you can order a "full bill" for the month for which the call logs are desired. Each year, AT&T will provide one bill statement for free. During that same year, each additional statement costs (as of today) $5. The statements are mailed and require 7-10 days to arrive.

I hope this helps.
