Verizon is taking an extra step to protect its phones.
The nation's largest wireless carrier said Monday that it would begin locking the phones it sells to consumers, which will prevent them from using a SIM card from another carrier. Initially, the phones will be unlocked as soon as a customer signs up and activates the service. But later in the spring, the company will begin the practice of keeping the phone locked for a period of time after the purchase -- in line with the rest of the industry.
