Abstract
Short message service (SMS) copy forward and carbon copy methods and systems are provided. An SMS message is received at a first network device and is delivered to a first mobile device. A copy indication associated with the sender or the first mobile device instructs the first network device to send a copy of the received SMS message to a second mobile device. Responsive to the copy indication, the first network device replaces a teleservice type identifier in a teleservice space of the received SMS message with a message copy indicator based on a predetermined mapping between the teleservice type identifier and the message copy indicator, to form a modified SMS message. The modified SMS message is sent to a second network device associated with the second mobile device. The second network device detects the message copy indicator to determine whether the modified SMS message is enabled for further copying.
