This quoted from Verizon's FAQ's on testing:
Can I view and/or print my text messaging content?
- Users who login to the Verizon Wireless text messaging website to send/receive text messages can view/print content and corresponding replies for 120 hours after the original message is sent.
- Messages sent from or received on your device cannot be viewed in any other medium. You can, however, forward text messages to an email address, and then view/print them just like any other email.
- Text messaging content is not available through My Verizon.
