So the International Version has no 4G support that has been established; however, their could be a possible way to still get 4G. I have seen with the SG2 International and The SG2 Tmo if you flash the modem of the tmo one onto the international they got 4G on Tmo. I have also read that i think it was the nexus or galaxy note or something had a locked band that they unlocked.... I heard that a radio probably wont change anything but does anyone else have any ideas?
