Just bought a xperia Z3 Dual,
The device shoes no LTE icon in quick settings and settings menu.
I can not activate it.
Solutions?

Is your Xperia compatible with your carrier's LTE bands? 

Settings > more > internet settings > accept 

also

settings > more > mobile networks > make sure that LTE its selected

4G/LTE is selected, and xperia is compatible with the carrier
The icon itsel isn't there
