Securing your personal digital media, like photographs, videos and text messages is important. As a result, almost all cell phone manufacturers install "locks" on their handsets to prevent unauthorised access to your data if your phone is lost or stolen. The Sony Ericsson K810i phone comes with a SIM card lock to protect information stored on your SIM card and a phone lock to protect the phone itself. You will need to enter a numeric code to unlock your K810i.
