If you’re a former Nextel customer who wants to use your phone with a new wireless provider, you first have to unlock the device. Some websites charge a fee for providing unlock codes, but there’s no guarantee they’re going to work. It’s best to just contact Nextel customer service and ask for the unlock code. Nextel typically provides unlock codes to customers in good standing, those who have completed their service agreement or for those who want to use their cell phone for international travel.
