Key in the code through your dial pad on your cellphone. After that, Verizon compatible unlocked phones will begin to run on Verizon's network as its service provider. Bootloader Unlock Method: Traditional root methods rely on an unlocked bootloader, and you can't use TWRP custom recovery without one. Some phones allow you to unlock the bootloader with a single Fastboot command, while others may require you to get a code from the manufacturer's website beforehand.
If you don't care for a carrier's handholding, you might be able to unlock your device to have some fun. Unlocking the bootloader on a phone can offer you tangible benefits like plentiful custom ROMs that can take a sad, outdated device and make it usable again. A device with an unlocked bootloader never need be held hostage by poorly designed software filled with crapware.
The Google Nexus phones are some of the most modder-friendly devices on the market. These phones, like the current Galaxy Nexus, ship with a locked bootloader, but no encryption. With a fastboot file and the Android SDK, users can simply use the 'fastboot oem unlock' command, and the phone is ready for modding. Nexus phones support bootloader unlocking in a secure way — it will do a factory restore when unlocked in order to protect user data. The phone can also be re-locked if you need warranty service.
HTC phones are encrypted, but as long as you don't mind obliterating your warranty, HTC's developer tools can be used to unlock the bootloaders on all its encrypted devices. This is a fairly easy process, but don't expect the carrier to help you if anything goes wrong, whether or not it's your fault. When an HTC phone is unlocked, it stays that way.
Sony devices use a similar system to the one HTC owners get. You use the Sony website to get a bootloader unlock code based on your device's IMEI serial number, then use the Android SDK to push a fastboot command to the phone and enter the code. This process is also irreversible.
Motorola took a lot of heat from the Android community after it became clear that it was implementing encrypted and locked bootloaders. This practice goes all the way back to the Canadian Motorola Milestone (the original Droid in the US) in 2010. After saying in early 2011 that an unlock solution was coming for developers, we're still waiting. With the locked bootloaders on Motorola phones, users are severely limited in what can be modified on the phone.

Samsung's Galaxy S II phones don't actually implement bootloader locking at all, which might be problematic in some situations. Meanwhile, Motorola doesn't even have an unlock solution for its encrypted bootloaders. The best course of action is probably the middle ground system at work in the Nexus phones; a safe and secure method for accessing the bootloader.
