first and second quotes are the same thing written differently(that's what i'm currently able to do with the ethernet shield and one of the goals of my project, the last quote is the actual information i need from this thread.
I'm not asking HOW to do it, what i'm asking if it's possible to do it similarly as the ethernet shield with the SIM800L shield.
this is my current code using the ethernet shield.
