Abstract
The subject matter described herein includes methods, systems, and computer program products for providing a bi-directional data path to a SIM containing an executable program. According to one system, a subscriber identification module (SIM) is provided that includes a memory configured to store one or more executable instructions and a processor configured to execute the one or more executable instructions to generate one or more commands for controlling a device. At the SIM, a bi-directional data communications link, such as a serial communications link to the SIM processor, is simulated in software. The simulated communications link provides for bi-directional data communications between a customer application which is executed on the SIM and an external device which is not executed on the SIM, such as a microprocessor or cell module.
