The BlackBerry Bold 2 is part of a line of high end smartphones by Research In Motion, originally released in 2008. The Bold 2 was released in 2009, and incorporated more memory and a newer version of the BlackBerry operating system, as well as replacing the original trackpad with an optical trackpad. The battery also lasted 50% longer, and the phone was smaller and lighter.
One thing they didn’t change with the upgrade, however, is that the phone remains SIM locked, so that you cannot use the phone with carriers other than the one which sold the phone to you, even though the phone is capable of working with any GSM network. You have to unlock the BlackBerry cell phone before you can have a choice of GSM networks.
Phone unlocking is perfectly legal. The cell phone is manufactured unlocked, and Research In Motion added a SIM lock at the request of the carriers. By using manufacturer unlock codes to unlock the cell phone you are merely restoring it to factory settings. It does not void your warranty, and the phone will remain unlocked even if Research In Motion rolls out new software to your phone. Unlocked phones also have higher resale values than ones that are still SIM locked.
To unlock a mobile phone for free, simply ask your carrier for the necessary codes for your IMEI number. Because the process to unlock a BlackBerry cell phone is somewhat complex, you may wish to stop into your carrier’s local store and have them perform the phone unlocking for you.
If you can’t unlock the mobile phone for free, you can always purchase a SIM card from a different phone carrier, available inexpensively at any cell phone store, and buy the phone unlock codes from a third party vendor online.
Once you get the specific code needed to unlock your phone, you can unlock your Bold 2 by following these steps.
1. Power on your phone, and go to the home screen.
2. Go to Manage Connections.
3. Select Turn All Connections Off.
4. Go to Options.
5. Select Advanced Options. (If you do not see an Advanced Options selection, select Device and then Advanced Settings.)
6. Select SIM Card.
7. Type the letters MEPD.
8. The phone shows that network locking is active.
9. Type the letters MEP2.
10. Enter the unlock code that you were given.
11. Press Enter, and wait for the phone to acknowledge the code was accepted.
12. Power off your phone, remove battery, reinstall battery, and then power it back on.
13. Go to Manage Connections.
14. Select Restore Connections.
