The SIM file system resides in which type of memory?

Explanation:
SIM file system must persist data even when the device is powered off. That persistence is provided by non-volatile memory on the SIM card, such as EEPROM or flash. Volatile memory like RAM would lose the SIM data when power is removed, which would break access to essential information stored on the SIM. Cache memory is also volatile and designed for temporary, fast-access data, not for storing a persistent file system. Therefore, the SIM file system resides in non-volatile memory.
