Unlocked iPhone 6S: A1633 vs 1688<\/h2>\n

Both the A1633<\/strong> and A1688<\/strong> work well on any US carrier, including Verizon, AT&T, T-Mobile and Sprint. The A1633 is the most comprehensive model.<\/p>\n

The A1688<\/strong> is for GSM and CDMA, sold as the carrier model for Verizon, T-Mobile and Sprint. There is one band difference that makes the A1633<\/strong> preferred for AT&T users. The A1633 model supports Band 30 on 2300 Mhz (2.3 Ghz) also known as Wireless Communications Service (WCS). Band 30 is an LTE band sometimes used by AT&T for big cities. The A1688 will work fine on AT&T, just won\u2019t take advantage of band 30.<\/p>\n\n\n\n\n\n
