Names for phone numbers on bill?

myphone54

Is it possible to find out the names of incoming and outgoing calls that appear on my bill. When I review my bill online, it just lists the phone numbers. I can't remember 1 month back of who called and it drives me bonkers.  I don't have all of  them saved in my phone. Any help would be appreciated. Thanks.

Have you tried looking them up online?  Search for a "Reverse Phone Directory."  If you don't have their numbers saved in your contacts, and they aren't listed in the directory, I don't think you'll be able to find a name for them.
