How to enter the Unlocking Code for a BlackBerry Model

General Information about the BlackBerry unlocking codes
When you receive your code it will be in one of two formats (depending on your model) 

1: A single string of 4 or 5 long numbers or
2: Again a string of numbers, but with some identifying letters between them (EG MEP/NCK etc) 

If you receive format 1, then these are simply 4 or 5 codes that need to be tried. (So when you are asked to enter the unlocking code, you need to try each one, starting with the 1st). 

If you receive format 2, then please refer to the table below for your code. 

Here's an example of how your code will break down: 

[th]Type[/th][th]Example[/th][th]MEP[/th]

IMEI:	351238034369xxx	n/a
SIM Code:	6123343501466xxx	MEP1
NCK Code:	7123039679046xxx	MEP2
Subset Code:	123211566752xxx	MEP3
Prov Code:	8261232688272xxx	MEP4
Corp Code:	3851231232390xxx	MEP5

Note: BlackBerry in 90% of countries will only require the MEP2 code 
We suggest you copy codes to a notepad and enter them very carefully. 


Please make sure the wireless mode is turned off before attempting to unlock your Blackberry phone

Each unsuccessful unlock attempt (EG entering the code incorrectly) will delay the next attempt by 10 seconds, and so on.
You are limited to 255 attempts before the phone is permanently blocked.

NOTE: On some phones you are limited to only 10 attempts 

To unblock a phone, it must be taken to a RIM Blackberry Service centre. In the meantime there will be no outgoing calls including emergency calls.[/size]
