Apple iPhone X A1901 AT&T 256GB Space Gray
The Apple iPhone X A1901 is a bar-style smartphone with a 5.8-inch touchscreen and 256GB of internal storage. It runs iOS 15.4 on an Apple A11 Bionic processor clocked at 2.4 GHz with 3GB of RAM. The device features a 12MP dual camera system with optical image stabilisation and a sapphire crystal lens cover. This unit is locked to the AT&T network and cannot be used with other carriers.
Build integration and network constraints
Because the handset is locked to AT&T, it requires an active AT&T SIM plan to access cellular services; it will not accept SIM cards from other networks. The 256GB of built-in storage removes the need for a microSD card, which the phone does not support. Wireless charging is supported, freeing the Lightning port for data or audio accessories. Integrated GPS provides location services without extra hardware.
Ideal for AT&T users wanting high storage
This model suits buyers who are committed to AT&T and want a high-capacity iPhone X in Space Gray with a dual-camera setup. It is not suitable for anyone who needs an unlocked device to switch carriers or travel internationally with local SIMs. Buyers who require expandable storage via memory card should look elsewhere. Those needing a newer iOS version than 15.4 or a more recent processor generation will not find that here.

Questions about this item
What thermal limit appears first when the A11 Bionic runs at 2.4 GHz continuously?
The A11 Bionic will throttle its 2.4 GHz clocks once the internal temperature reaches the factory-set thermal ceiling, so sustained heavy workloads will see reduced frequencies.
How much heat and fan noise does the iPhone X produce during all-day use?
The iPhone X has no fan; it relies on passive cooling, so it runs silently but the glass-and-steel chassis becomes noticeably warm under prolonged load.
Which AT&T SIM must I already have for this A1901 model to connect to the network?
This A1901 unit is locked to AT&T, so an active AT&T nano-SIM (or compatible eSIM profile) is required before the phone can register on the network.
