If you are trying to unlock your phone and have the unlock code try the following:
blackberry 9520 invalid sim
Turn OFF your BlackBerry 9520 & insert a SIM card to the Sim slot.

Turn ON your BlackBerry 9520 & Go to "Manage Connections" > "Turn All Connections Off" to set all the connections (WIFI and Radio) off

Go to "Options" and select "Advanced Options"

On the "Advanced Options" menu select and press on "SIM Card".

Hold your BlackBerry 9520 horizontally and click on the BlackBerry button to show keyboard

Type "MEPD" (The letters will not appear). and a menu will appear on screen (or try to type "MEPPD" instand).

Type "MEP2" and it will ask you to "Enter network MEP code". in case you dont get this screen repeat step 6 and on step 7 try "MEPP2" or "MEP4".

Type the unlocking code and Press "Enter".

You will see a message says "Code accepted", in case you get an error message - try to use the other code(s) in the same way.

Restart your BlackBerry 9520 and turn ON the connctions - your BlackBerry 9520 is now unlocked!

Good Luck hope this helps.
