I am new to this forum. I am a system engineer who loves hardware (anything from a microprocessor, a sensor, an antenna... to a SIM card). And lately I am trying to get into the SIM development world but I find it very hard to find references, books, courses or any other resources for learning.
My question is: if I wanted to learn properly, what is the path to do it?
- Should I take a course? (Is there any?)
- Should I start with some sort of guide (which one?)
- What are the main references for learning (books, papers...)
Regards!
