Hello, I have connected ST4SI2M0020TPIFW chip to my Quectel EC25 modem, but I'm not able to add,switch,delete profiles on that eSIM, I gather logs and asked Quectel itself what's wrong with it.

From the log, it seems the card didn't recognize the command "8x E2 91", the card return 0x69 0x85 when the above command sent to the eSIM card

So something is wrong with eSIM itself, why it does not recognize command?
