I am interested in ST4SI2M0020TPIFW product, however I have questions about it. I have some experiences with eSIM-enabled consumer LTE modems, like DW5821e-eSIM & FM350 which have built-in eUICC. But using them is impractical due to their cost and other factors. Now I am looking to use GSM modules like simcom SIM900/800, paired with a 3rd party eSIM chip and a little research revealed that most if not all eSIM chips in the world are manufactured by ST. The usual eSIM provisioning workflow involves downloading a profile from carrier's SM-DP+ server and installing it on the eUICC. The communication with the eUICC is done through APDU commands. I have developed my own LPA solution, though some open source software like LPAC already exists and with consumer grade eSIMs it works fine, as long as the cellular module supports necessary AT commands. But I can see that the chip in question is meant for M2M usage and industrial scenarios. So the main question is whether it supports same APDU command sets and an eSIM profile could be provisioned the way I described, rather than 'pushed'. I have seen that those ST products come with a Truphone profile which I don't care much about and would probably like to remove, but I also read that profile management is done through Truphone's platform, which is not something I am looking for. Thus, will I be able to install/activate/remove profiles independent of Truphone system the way I did it on consumer eSIM chips, does the ST4SIM-200M confirm to the same standards? Will it act like any other SIM/smartcard with regards of APDU commands? Also, since this MCU is a 'system-in-chip' with its own CPU, does it by chance have its own AT command set or any interface other than APDU commands (if those are indeed supported)?
