You can do this by finding out which unlocked iPhone X model number supports your carrier’s specific wireless bands.
The unlocked iPhone X comes in two US carrier models: A1865 and A1901. There is also the A1902 model, but it is intended for Japanese carriers, so we aren’t including it in this article.

iPhone X model A1865 Carrier Compatibility
The iPhone X A1865 is the GSM+CDMA model and works on pretty much any US carrier, including CDMA carriers like Verizon and Sprint. A1865 models have CDMA support, which Verizon and Sprint use for 3G connectivity, and it also works on their 4G LTE networks.
The A1865 is sold by Apple as the SIM-free model and is typically used by Apple for replacement devices.
iPhone X model A1901 Carrier Compatibility
The iPhone X A1901 is the GSM version, sold as the carrier model for AT&T and T-Mobile, and doesn’t fully support CDMA networks. That means the A1901 will not support Verizon’s or Sprint’s 3G CDMA networks, so if you want a phone that works on all four carriers, you need to get the A1865 model.
