This unlocked model works on both AT&T and T-Mobile in US only. So what does this means ? From now on, you will not need a contract with those carriers if you buy this specific model. The SIM-free iPhone 5s comes in 16GB, 32GB, and 64GB capacities for $649, $749, and $849, and it comes in the same space gray, silver, and gold color options as the carrier-tied versions. The models ship in 1-2 weeks from Apple’s online store, and should become available in Apple retail stores in the coming weeks.
Mark Gurman of 9to5Mac first spotted the change:
Apple today released an unlocked GSM version of the iPhone 5s on its online store for the United States. This version of the iPhone 5s includes the same exact capabilities of the non-unlocked models, but does not include a SIM card. Users who buy this version of the iPhone will need to supply their own SIM card.
The central benefit of an unlocked iPhone is that it can work on many GSM networks across the globe with no contract. For frequent world travelers, this option is worth looking into.
Apple explains:
If you buy iPhone for T-Mobile, it will arrive with a nano-SIM card already installed that you can activate by visiting an Apple Retail Store or a T-Mobile store or by calling T-Mobile. If you buy a SIM-free iPhone, you will need to purchase a GSM-compatible nano-SIM card separately.
In the United States, you can purchase such a SIM from AT&T or T-Mobile. When you travel internationally, you can use a nano-SIM card for iPhone 5s from a local GSM carrier. The unlocked iPhone 5s model is A1533 (GSM). For details on LTE support, see www.apple.com/iphone/LTE.
The online Apple Store at press time said the SIM-free iPhone 5s was available to ship in 1-2 weeks versus 3-5 days for iPhone 5s models that ship with a T-Mobile SIM.
The SIM-free unlocked iPhone 5s has not yet arrived to Apple Stores, but should become available in a few weeks, ideally before Black Friday officially marks the start of this year’s holiday shopping craziness.
