Using LTE Band 3 (1800 Mhz)

I am relocating to Dubai for work next month, where they have 2 main cell providers that both provide LTE on Band 3 / 1800 Mhz.
I have an unlocked T-Mobile Note 4 and want to know there is anything I must do in order to get the phone working 100% with LTE on the cell network in Dubai.
Samsung's website say that these are the supported bands of the SM-N910T:

NETWORK
Frequencies and Data Type
2G GSM : GSM850, GSM900, DCS1800, PCS1900
3G UMTS(WCDMA) : B1(2100), B2(1900), B4(AWS), B5(850)
4G LTE FDD : B1(2100), B2(1900), B3(1800), B4(AWS), B5(850), B7(2600), B8(900), B12(700), B17(700)

So, if I throw in my Etisalat SIM card when I get to Dubai, should I get calls, text & LTE working at full-speed?
Seems like the answer should be yes, but I'm a bit skeptical, since the Galaxy S5 supposedly supports all of the same LTE bands , then I come across this thread :

Any input is appreciated as I will be relying heavily on my phone & need it function correctly as soon as I get there
