A:Answer Yes, per the info posted here, on Best Buy's site, since this phone is unlocked, you can purchase it and activate service with one carrier, and then change service to a different carrier at a later time.
"Here are your unlocked activation options
We're currently only able to activate service on this unlocked phone with Verizon, AT&T and Sprint. If you prefer to use a different carrier, you can buy it today and activate service later. Either way, this unlocked phone allows you to switch carriers whenever you want."
