HTC has revealed a new addition to its rapidly-growing lineup of dual-SIM devices. The Desire 400 was listed on the company’s Russian and Ukrainian websites, without either showing an official announcement. However, both sites reveal that the device will ship with dramatically different internal specifications, but the overall external appearance will remain the same.

According to HTC Russia, the Desire 400 will pack a 4.3-inch display with a resolution of 800 x 480, a Snapdragon 400 chipset powered by four 1.2GHz CPU’s, 1GB of RAM, an 8-megapixel rear-facing camera coupled with an LED flash, a 1.6-megapixel front-facing shooter, 4GB of internal flash memory (expandable up to 64GB via microSD), dual-SIM capabilities and a 1,800 mAh battery — which, according to the Happy Telephone Company, provides juice for about 12 hours on 3G talk time.

Meanwhile, the Ukrainian variant of the handset differs by way of camera and processor configurations, apart from this, all other internal components are the same. Instead of the quad-core CPU, 1.6-megapixel front-facing camera and 8-megapixel shooter found on the Russian model, this edition of the smartphone will feature a dual-core central processing unit, a 5-megapixel rear-facing and VGA front-facing camera.

In terms of software, both devices will ship running the latest build of Android 4.2.2 Jelly Bean skinned with HTC’s Sense 5.0 custom user interface, which includes loads of great software tweaks, such as BlinkFeed, Zoe, Quick Share and Do Not Disturb.

Unfortunately, there’s no word on pricing of the Desire 400 dual-SIM, but we do know that the handset will be available to purchase in three different colorways: white, black and light blue — all of which can be seen pictured at the top of this page.
