Abstract
Systems, methods, and apparatus are disclosed to enable backup wireless devices. An example method disclosed herein includes receiving a first activation code from a first wireless device, comparing the first activation code associated with the first wireless device with a first activation code in a database, activating the first wireless device when the first activation code associated with the first wireless device matches the first activation code in the database, and when a second wireless device is active, deactivating the second wireless device in response to receipt of the first activation code associated with the first wireless device.
