Apple now offering SIM-free iPhone 6 and 6 Plus models in the US starting at $649

Apple has begun offering SIM-free models of its new iPhone 6 and 6 Plus handsets in the United States this morning. The company unveiled the two devices in early September, and launched carrier versions of them later that month for Verizon, Sprint, AT&T and T-Mobile.

The unlocked, SIM-free versions cost the same as the unsubsidized iPhone models. So the 16GB, 64GB and 128GB iPhone 6 models cost $649, $749 and $849 respectively. Similarly, the 16GB, 64GB and 128GB iPhone 6 Plus models cost $749, $849 and $949 respectively.

When the iPhone 6 and iPhone 6 Plus models went on sale in the U.S. in September, the only unlocked iPhone option came with the T-Mobile SIM in the box, or one had to buy an iPhone with a carrier contract bundled with the device.

There has been a significant delay in selling the unlocked, SIM free versions of iPhone 6 and iPhone 6 Plus in the U.S., as Apple usually launches the unlocked version of the new iPhones in November. It probably indicates that Apple is still struggling to keep up with the demand for iPhone 6 and iPhone 6 Plus.

Apple launched the iPhone 6 and 6 Plus in September of last year with larger 4.7-inch and 5.5-inch displays, slimmer casings and other improvements. The handsets have been wildly popular thus far, with supply only just now—3 months later—beginning to catch up to consumer demand.
