Until recently the Alcatel Idol 4S Windows 10 device was only available from T-Mobile US. The modern Snapdragon 820 handset was locked to the network and therefore not available to AT&T users or the rest of the world.

That’s all changing today however, with the handset now on sale in the Microsoft Store, fully unlocked.

Idol 4S comes with a 5.5-inch Full HD AMOLED display protected by Dragontrail Glass, a 21MP rear camera, and an 8MP front camera. It is powered by a quad-core Qualcomm Snapdragon 820 clocked at 2.15GHz, 4GB of RAM, 64GB of internal storage (with microSD support), and a 3000mAh battery.

It supports bands GSM network: 850/900/1800/1900, UMTS 2/4/5, LTE2/4/12. AT&T 4G HSPA and HSPA+ use 850Mhz(Band 5) and 1900Mhz(Band 2) bands and AT&T LTE uses Band 17(700Mhz), Band 5(850Mhz), Band 2(1900Mhz), Band 4(1700/2100Mhz) currently, so the device should be compatible, depending on the area.
