As we all expect at this time every year, the new iPhones have arrived and again we get two new phones, the iPhone 6S and iPhone 6S Plus.
The iPhone 6S and 6S Plus come in 6 models, including A1633, A1634, A1687, A1688, A1699 and A1700, and they have different cellular connectivity. Fortunately, there are less model numbers than iPhone 6 last year and Apple also covers 3 more LTE bands (23 as compared to 20 bands on iPhone 6). 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). AT&T customers will also notice a better experience as some models support the new LTE band 30. The new generation also features LTE-Advanced (LTE-A) which supports download speed of 300Mbps and Voice-over-LTE (VoLTE).
