I need a GSM modem that supports openAT. I want to change the Originator Address (OA) when sending an SMS data packet. I need to be able to specify the exact data packet that gets sent to the carrier network.
If you have knowledge and have accomplished this task before, please contact me.
You must supply me a proper developers manual and proper instructions on how to do this. I also require the gsm modem model name for this task.
If you also have experience in making custom gsm modems, that would also be beneficial, but you must be able to do the task above.
