That would be quite a feat if it did. I don't believe exynos or the brand new processors handle all three, unless they are using two different processors. The latest Qualcomm processors do. I could be wrong but it would be impressive if it is. More then likely there are two versions, one with LTE and CDMA and the other is quad-band or penta-band GSM
