Wind Xperia Z3 topic

Hey all, I purchased an Xperia Z3 from Wind here in Canada. Its the D6603 model. Trying to use it on Rogers but theres no selection in network mode for LTE. Anyone know how to enable that in the phone itself? I remember on my S5 from wind I typed in a code with my imei # in the dial pad and from there I was able to choose what carrier then it automatically factory reset the phone and it was good to go with lte. However, I cant figure it out on the Xperia Z3. Any help would be greatly appreciated

Thanks!
