A system and method for providing a user-accessible Internet-based mobile messaging log that records messages communicated between an Internet-based sending device and an SMS-capable mobile device. An SMS messaging log is created for each Internet-based user that sends messages to SMS-capable mobile devices. The mobile user is then able to access their SMS messaging log via the Internet and view the SMS messages sent to the SMS-capable device. The message log also records and displays replies sent by the SMS-based user in response to the sent message. The system and method utilize a unique tracking identification number to match original messages to replies in the mobile messaging log.
