A SIM PIN protects your SIM card from unauthorized and unintentional communication or internet browsing. Plus, whenever you restart your phone or remove the SIM card, your SIM card will automatically lock, showing "Locked SIM" in the status bar. To unlock it and restore your access, you’ll need the SIM PIN.

What You Should Know about a SIM PIN

  1. It’s optional; you don’t have to have one if you don’t want one.
  2. Your default SIM PIN is 1234.
  3. You’ll need the SIM PIN whenever you:
  • Reboot or turn off your phone
  • Change your SIM PIN
  • Want to restrict call capabilities
