Being able to manage the usage on your account is important, Nancy36. I am happy to inform that you may view text messaging history such as number the line sent/receive a text message to, date, and time of the message. For directions on how to view your text messaging usage online click: http://spr.ly/66091Ai9F
From a computer, login to your account. Choose usage then usage overview, scroll down choose device you need and you will see text and phone numbers info. I recently had to do this and it helped a lot. Hope this helps you as well.
