Verizon has not embraced phones from outside its product lineup the way AT&T and T-Mobile have. But Verizon seems to be loosening up on unlocked phones. It will now activate compatible, unlocked versions of the iPhone 6 and Nexus 6. One needs a device ID and a Verizon SIM. Verizon is doing it to honor the industry's voluntary code of conduct for American carriers, meant to keep the government at bay.
