With number portability already possible in the U.S., cell phone users are freely allowed to carry their numbers to whichever carrier they choose. Taking your handset with you to a new carrier, however, is a completely different story.
Many cell phone carriers “lock” their phones specifically to their network, meaning that any phone bought from one network cannot be freely used on another network using the same technology. Carriers often do this in an effort to prevent consumers from taking advantage of special subsidized phone pricing and then jumping to another service provider.
Today, the U.S. Copyright Office changed all that, and is legally allowing cell phone users to break the software locks that cell phone carriers place in their phones. However, carriers are still permitted to software lock their phones.
