How do I get copies of old cell bill no loger in service "2001"

You could try writing to the company and requesting them, or call them?

The procedures are different for each cell carrier. When I worked for Verizon you would have to call in and request an Archived bill from that year. If the bill was older than 3 years we would have to put in a special request to have the bill pulled from the archives and mailed out. The process takes 6 to 8 weeks. The very first step is calling the company that you need the bill from. And it doesn't matter if the account is no longer in service. As long as you know the name it was under and the social security info they can find it, even in deactivated accounts.

You can't get the phone records that fare back. The most I have seen go fare back is 5 years and that's as fare as it can go. Something along the lines as for tax purposes.
