Learn how to protect your phone, and keep your data secure.

Set your phone to lock automatically

Want to protect your phone against unauthorized use? Create a security code, and set your phone to lock itself automatically when you're not using it.

  1. Select > Settings > Phone > Phone management and Security settings > Phone and SIM card.

  2. Select Phone autolock period > User defined, then set how long before the phone locks itself.

  3. Create a security code using at least 4 characters. You can use numbers, symbols, and upper and lower case letters.

Keep the security code secret and in a safe place separate from your phone. If you forget the security code and your phone is locked, your phone will require service. Additional charges may apply, and all the personal data in your phone may be deleted. For more info, contact Nokia Care or your phone dealer.
