Nokia Lumia 2520 - Access codes

Ever wondered what the different codes on your tablet are for?

PIN code

(4-8 digits)

This protects your SIM card against unauthorized use or is required to access some features.

You can set your tablet to ask for the PIN code when you switch it on.

If not supplied with your card or you forget the code, contact your network service provider.

If you type in the code incorrectly 3 times in a row, you need to unblock the code with the PUK code.


This is required to unblock a PIN code.

If not supplied with your SIM card, contact your network service provider.

Security code (lock code, password)

This helps you protect your tablet against unauthorized use.

You can set your tablet to ask for the lock code that you define.

Keep the code secret and in a safe place, separate from your tablet.

If you forget the code and your tablet is locked, your tablet will require service. Additional charges may apply, and all the personal data on your tablet may be deleted.

For more information, contact Nokia Care or your tablet dealer.
