If dual-SIM card slots are a must for you, many of the latest flagships are going to be unsuitable. But a leaked Samsung prototype suggests the South Korean company is working on a dual-SIM version of its new Galaxy S6, and it’s going to be just as good as the original.

Samsung often follows up its devices with “Duos” variants that have two SIM card slots, so it’s not too surprising to see the company is working on bringing the same functionality to what will surely be its best-selling smartphone to date.

This particular prototype was discovered in the Philippines, PhoneArena reports, and it’s clearly an early model with a plastic shell, rather than the fancy glass and metal form factor the regular Galaxy S6 is sporting.

But we know it’s a Galaxy S6 variant because of its software and specifications. The device packs the same 5.1-inch Quad HD display, octa-core Exynos 7420 chipset, 3GB of RAM, and 16-megapixel rear-facing camera with f/1.9 aperture.

The device also runs Samsung’s latest TouchWiz user interface, but it has a new “SIM card manager” section in its Settings menu that isn’t present on the regular Galaxy S6. This is where users can manage each SIM, and specify whether they wish to receive calls on both.

Like previous Duos devices, it’s likely the Galaxy S6 Duos will only be available in select markets where dual-SIM devices are popular. But we’ll have to wait for Samsung’s official announcement to be sure.
