Information
Lock SIM card.
Rationale:
If your device uses a SIM card(s), enable SIM card lock. A SIM card PIN locks the SIM and
prevents anyone from removing the SIM card from your device and use it on any other
device without knowing the PIN. Also, you might choose to store your contacts and
messages on the SIM card and thus it is highly recommended that you safeguard this
valuable personal data by setting a custom PIN on the SIM card(s).
Note - Only phones that are not locked by the service provider can lock the SIM card.
