Preventing SMS message forwarding loops

A device may be configured to receive a message from a user device; and determine whether the message includes a parameter. When the message does not include the loop indicator parameter, the device may add the loop indicator parameter to the message to generate a first modified message, and output the first modified message toward an intended recipient of the message. When the message includes the loop indicator parameter, the device may determine whether a value of the loop indicator parameter exceeds a threshold value. When the value of the loop indicator parameter does not exceed the threshold value, the device may discard the message. When the value of the loop indicator parameter exceeds the threshold value, the device may modify the value of the loop indicator parameter value to generate a second modified message, and output the second modified message toward the intended recipient of the message.
