Microsoft Lumia 640 XL LTE (pictures)

The Lumia 640 XL LTE from Microsoft Devices takes the basic 640 and bumps up the screen, battery and camera, while adding in 4G connectivity.

The rear camera jumps up to 13-megapixels with Zeiss optics.

The whole unit stays pretty slim for such a budget smartphone -- just 9mm or 0.35-inch thick.

The 13-megapixel rear camera is complemented by a 5-megapixel front camera, a large improvement from the 0.9-megapixel lens on the on the 5-inch 640.

While dual-SIM variants exist, we looked at the single-SIM LTE version.

Beside its smaller stablemate, the XL really stands out.
