Verizon phones on the 4G LTE network do not require an unlock code, while locked 3G phones can be unlocked with the codes "123456" or "000000." The Unlocking Consumer Choice and Wireless Competition Act signed into law in 2014 allows cell phone users to unlock their phones under certain circumstances.
Most of Verizon's contract cell phones are not locked. The 3G network phones that are locked are the non-iPhone Global Ready 3G phones. The appropriate code should be included in the phone user guide. If the information is not included, a call to Verizon customer service at 800-922-0204 is necessary to receive the correct code.
Some prepaid-plan cell phones have locked SIM cards. Phone-in-the-Box Prepaid phones are restricted to Verizon's prepaid services for six months after activation and are locked to the Verizon Wireless network for 12 months. After the 12-month period, the phone can be unlocked using either "123456" or "000000." If the code is not included in the phone user guide, cell users can call Verizon's customer service number to have the phone unlocked.
Phones for deployed military personal can be unlocked without restriction. Either contract or prepaid users can call customer service and have a Verizon phone unlocked.
