How to Unlock A Blackberry Phone Using Unlock Code

Blackberry phones purchased with a cellphone network contract commitment are locked with the respective network provider. These phones cannot be used with any other network unless they are unlocked following the proper cellphone unlocking procedure. In order to unlock a Blackberry smart phone, it is necessary to obtain a subsidy unlock code from the cellphone service provider.

Things You'll Need

• IMEI (International Mobile Equipment Identity) number.
• SIM card from network provider other than current provider.
• USB data cable for Blackberry phone.

Instructions

1. Insert the network provider's SIM card, for example, AT&T SIM card and power ON the phone. Turn OFF all wireless radio/network connections. Find the phone's IMEI number by keying *#06# and note down the displayed 15 digit number.

2. Navigate to the phone's Options > Advanced Options menu and Select SIM card option. Key in the code MEPD. This will display phone and Network details. Note that the "Network" option in "Personalization" options is in the Active state which means that the phone is currently locked to network provider.

3. Key in the code MEP2. The following message will be displayed on the screen: "Enter Network MEP code (10 left):"
   The number of tries are limited so make sure that the correct MEP code from your network provider is entered. This is also called the subsidy unlock code.

4. Press the Enter key after entering the correct unlock code. This will unlock the Blackberry phone. Verify that the "Network" option in "Personalization" menu is in "Disabled" state. This means that the phone is unlocked and can be used with any network provider in the world. Reboot the Blackberry device for proper operation.

5. Insert a new SIM Card from another network provider and turn on all the wireless radio/network connections. The phone is unlocked successfully if incoming and outgoing calls can be connected or else contact network provider for solution.

Tips & Warnings

• Backup your address book contacts as well as important data from your phone on your computer by using a USB data cable for the phone and Blackberry Desktop Manager software. There is an option called "Backup and Restore" in Desktop manager software which can be used for this purpose.

• Generally cellphone network providers give away unlock codes when customers have only a few months (six months) left in their phone contract commitment.

• Do not exceed 10 tries while entering the unlock code or else it will permanently lock the phone with current network.
