General Information about the codes for your Blackberry 8100
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:
Model: Blackberry 8100
1. Go to Options Menu
2. Then Advanced Options
3. From the SIM Card menu, hold down the shift key (right of the zero, caps) and press 'MEPPD'
4. Next you should see the unlocking screen, hold down the ALT key (left side below @ symbol) and type 'MEPP2'
5. Finally enter the unlock code provided
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.
Question: My phone asks to enter a PIN number
Answer: For SIM cards with PIN ENABLED you will be required to enter a PIN. This is not the unlocking code that has just been provided. For information concerning the PIN, PIN2, PUK and PUK2 codes for a SIM card please read the manual that came with your phone. This is NOT a handset unlocking difficulty.
IMPORTANT: Please make sure the wireless mode is turned off before attempting to unlock your Blackberry phone
