A phone is great when it works, but traveling can quickly reduce your expensive BlackBerry to an expensive paperweight if your phone isn’t unlocked for local carriers. You can get unlock codes from your carrier or from a third party if your carrier contract doesn’t happen to be up. Follow this guide to learn how to unlock any BlackBerry.
Get your BlackBerry’s IMEI number.
This unique identifier is required by either your carrier or the third-party unlock provider in order to get your unlock code. To retrieve your IMEI number, follow the appropriate steps for your device:
BlackBerry 10 – Go to Settings, then select Advanced. Tap Hardware from the dropdown menu that appears. Your IMEI number will be listed in the window.
BlackBerry 6 and 7 – Click Options, and then click Device. Click Device and Status Information to find the IMEI.
BlackBerry 5 and earlier – Click Options and select Status. Your IMEI will be displayed.
Your carrier will typically unlock your phone for free after your contract has been fulfilled. This means you will not be able to receive your code unless your contract obligations have been fulfilled and your phone has been completely paid off.
Go to Settings, select Security and Privacy, and then SIM Card. Scroll down and tap the Unlock Phone button. Enter your code and tap OK.
You have 10 tries to enter your code or your phone will be disabled.
First, disable all network connection. You can see your connections by opening the Manage Connections. Make sure that your WiFi and mobile networks are disabled.
Open the SIM Card menu by opening Options, selecting Device, Advanced System Settings, and then clicking SIM Card.
Type “MEPD” while in the SIM Card menu. A new menu will appear after you finish typing, and Network should show as Active. 71xx, 81xx, and 91xx model users will need to type “MEPPD”.
Type in “MEP [Alt]2”. If nothing happens, try typing “MEP [Alt]4”. You need to press the Alt key to enable typing numbers. 71xx, 81xx, and 91xx model users will need to type “MEPP [Alt]2” or “MEPP [Alt]4”.
