Abstract
A monitoring application and method in a disabled telecommunication device for monitoring communication sessions initiated by the device and detecting an emergency communication session that is initiated by the device. If an emergency communication session is detected, the monitoring application generates and transmits a message to a rating engine over a non-voice channel. The non-voice channel may be an unstructured supplementary service data (USSD) channel, a short message service (SMS) channel, or other like messaging channel. When the message is received via the non-voice channel, various callback techniques may be implemented to allow the disabled device to receive communications after the emergency communication session, even though such communications would normally be prevented as a result of a service lock.
