The Unlocked iPhone X comes in two models for US carriers: A1865 and A1901. There is also model A1902, but it is intended for Japanese carriers so isn’t considered for this article.

This post is part of our Unlocked iPhone Buyers Guide meant to answer all your questions about buying an unlocked iPhone.

This article will help answer the question: Which unlocked iPhone X should I buy for my carrier network? We’ll discuss the model differences, carrier compatibility, and help you choose the right iPhone X for Verizon, AT&T, T-Mobile, Sprint or your favorite MVNO.

Unlocked iPhone X: A1865 vs A1901

The A1865 is the GSM+CDMA model and works on pretty much any carrier, including Verizon and Sprint. The A1901 is the GSM-only version, sold as the carrier model for AT&T and T-Mobile, and won’t work fully with CDMA networks.

A1865 models have CDMA support which Verizon and Sprint use for 2G and 3G connectivity. The A1901 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 A1865 model.
