I want to actively read data sent by or to a sim card. All I found talked about dumping sim cards or about cracking its password.
What I want to do is really very simple.
For example, I have an old phone with a sim attached to it, with all the pins already also connected to arduino.
Then I send it an sms and I want to capture the data when it receives the sms and save that data as is.
Finally, I want to use the same data to make the phone think it got the same sms.
Until now, what I know is that I need two pins from sim card (clock to "coordinate" the procesor, and IO port to listen to the data).
Any information will be helpful
Thanks in advance
