What happens when you take a Samsung Galaxy S4 and you give it another SIM card slot? The GT-I9502 is born. This thing is pretty much the exact same phone as the Exynos 5 powered GS4, same screen, same RAM, same camera, same everything, except that there’s now an additional SIM card slot. Will this phone ever leave China? Can’t say. How much does it cost? Again, it’s a mystery.
