The iPhone 6s includes support for 23 bands of LTE. If you never leave the U.S. this isn't a huge deal, but for travelers this means you can drop a SIM card in from more carriers in more places and get the fastest speeds available on your iPhone 6s.
Apple also includes support for Band 12 or 700Mhz LTE which will improve coverage for some carriers in the U.S. T-Mobile boasts that this, "super spectrum doubles how far our signal travels from our towers, and works four times better in buildings." |
