Apple will begin selling unlocked versions of the iPhone 6 and 6 Plus in the United States on Tuesday, CNBC has learned.
The phones, which are not linked to any one carrier, will be sold at prices from $649 to $949 depending on screen size and storage space.
Apple will sell the unlocked phones both at stores and online.
The company has made similar moves in past with earlier iPhone models. Unlocked phones appeal to consumers who do not want to be tied to any one particular cellular provider.
They are also attractive to resellers who buy them in the States for sale to those overseas. As of Monday evening, unlocked models of the 6 Plus were selling for more than $1,200 on eBay.
