Unlocked iPhone 8 Plus: A1864 vs A1897

The A1864 is the GSM+CDMA model and works on pretty much any carrier, including Verizon and Sprint. The A1897 is the GSM-only version, sold as the carrier model for AT&T and T-Mobile, and won’t work fully with CDMA networks.

A1864 models have CDMA support which Verizon and Sprint use for 2G and 3G connectivity. The 1897 will not support Verizon’s or Sprint’s CDMA networks, so if you want a phone that works on all four carriers, you need to get the A1864 model.
