No

You need to unlock it from the carrier you purchased it from, if you are paying full price for a new one you should be able to get it unlocked out of the box.

If only it was that easy…

You'd more than likely have to pay a service like DoctorSIM.com to do so or you could check with your carrier about the option to unlock it.

Nope. Not that simple.

You have to call your carrier and get them to unlock it. The phone has to be paid off and you can't owe them any money… Lol, and let me just say this… If you call your carrier to ask about getting your phone unlocked and they tell you to call Apple… Ask to speak to somebody else. I'm a Sr. Technical Advisor for Apple and carriers do that ALL THE TIME

If you have a verizon 4gLTE they are automatically unlocked

Call the carrier
