Can someone kindly let me know which model of Xperia Z3 works in India, mainly for 4G LTE? Is it only D6653? 6653 has TD-LTE (Band 40) and FD-LTE (Bands 1, 3, 5, 7, 8, 28). I am planning to get one from US. Here it is D6603. Check page 5 here http://www-support-downloads.sonymobile.com/d6603/whitepaper_EN_D6603_D6653_1.pdf
