So eSIMs are not stored in the user data partition? (That's what I thought, but I just made an assumption) Are they stored somewhere deeper in the hardware?

eSIM profiles are not stored in the user data partition. Instead, they reside in a dedicated secure area of the device's internal hardware, specifically on the eUICC chip.
Wow, did not know that. But just to confirm, would they still stay, even after wiping the bootloader? Or perhaps, I would just need to be careful not to use the stock factory reset option.
