Sony Mobile will shortly launch a new Xperia Z3 Dual variant in Hong Kong with model number D6683. This particular model will support 4G LTE on both dual SIMs, so for users in Hong Kong it is likely to support both China Mobile and China Unicom 4G networks. No price or launch date has been set and don’t expect this variant to launch outside of China.
