you, for example, unlock your phone, change
security settings, or buy an app in Store. You
can define this PIN yourself.

separate from your phone.

recover or reset it in any way, your phone will
require service. Additional charges may
apply, and all the personal data on your
phone may be deleted.
For more information, contact the nearest
care point for your phone, or your phone
dealer.
