I'm trying to understand what is the difference between buying an unlocked iPhone 6 with T-Mobile SIM versus just a regular unlocked iPhone 6? They seem to be the same price: http://store.apple.com/us/buy-iphone/iphone6/4.7-inch-display-64gb-silver
Apple's info page states this:
Purchasing an unlocked iPhone means you will not qualify for the lower iPhone price associated with a contract or a carrier installment plan. The unlocked iPhone 6 model is A1586. The unlocked iPhone 6 Plus model is A1524. The T-Mobile iPhone 6 model is A1549. The T-Mobile iPhone 6 Plus model is A1522. For details on LTE network support, please see www.apple.com/iphone/LTE.
Can someone translate it?
