The A1688 is sold at T-Mobile (locked and contract-free), Sprint and Verizon in the US, as well as in Europe and Asia, including countries like the U.K., France, Germany, Singapore, Hong Kong, China, and Japan. This model will also work on both GSM and CDMA carriers. A1688: The global phone has almost the same bands as the A1633, except that there is no LTE band 30 (2.3 GHz WCS spectrum deployed by AT&T).
Apple also started selling the A1633 as the sim-free unlocked version on Apple Store and you will have to pay full price for the device. It is available on AT&T and some more carriers in the US. A1633: The iPhone 6S A1633 is the most comprehensive model. The new generation also features LTE-Advanced (LTE-A) which supports download speed of 300Mbps and Voice-over-LTE (VoLTE). AT&T customers will also notice a better experience as some models support the new LTE band 30. If you are on T-Mobile, you will see a boost in LTE signal, especially when you are inside buildings, because all new models include support for LTE band 12 (700MHz spectrum). Fortunately, the number of model numbers is the same as iPhone 6 last year and Apple also covers 3 more LTE bands (23 as compared to 20 bands on iPhone 6).
The iPhone 6S and 6S Plus come in 8 models, including A1633, A1634, A1687, A1688, A1699, A1700, A1690, and A1691, and they have different cellular connectivity.
However, you should be careful because your new iPhone might not be compatible with your carrier.
