Default Question about SHV-E120

I don't know if this is right place to do this question. If not I ask you forgiveness.

I'd want to know what LTE frequencies are really supported by this phone

seems that are 3 version K, S and L

Some store reports generically SHV-E120 supports LTE 800, 1800 and 2600 MHz
Some others reports K version supports 1800Mhz ; S supports 850Mhz; L 850Mhz too

Anyone can explain me better?
