The Hide SIM & operator info privacy option hides a whole range of personal information from cloned apps: your SIM card’s serial number (SSN), your SIM card’s phone number (some SIM cards still allow this to be read), your carrier / operator identifier, the operator name and country as well as neighbor cell tower information and current cell tower location. Basically it covers a good proportion of information provided by the Android telephony provider, including the very latest Android 9 Pie APIs.
