Compatible on South Korean networks?

Hey everyone!


I am just about to purchase the Xperia Z Ultra (Over the Galaxy Note 3) to be used in South Korea. I am a student here, and am fed up with Samsung's Galaxy line (And of course, iPhone is a joke). 


I use Korea's largest telecom operator SK Telecom, and they use mainly 4G LTE, as that is the norm by Korean telecom operators these days. 


Before I hit the pay button, I need to be sure this phone is not only compatible with Korean networks, but I can use all of the features while living here. Meaning I can access their LTE networks and take advantage of the crazy fast data speeds here (One of the perks of Seoul living). 


Does anyone have any similar experience with this? 


I found on SK's Wiki page the following speficiations for networks used here, and am not sure whether the XPeria Z Ultra is compatiable with one of the following (Am a bit techno-illiterate when it comes to these things)... 


Anyone can help me out? 




As of September 2012, SK Telecom operates 2G IS-95/CDMA 20003G WCDMA/HSPA+4G Mobile WiMAX, and LTE network.

Re: Compatible on South Korean networks?

I'm in Seoul - the C6833 is supposidly compatible with pretty much every LTE band in the world. - I'm on KT and it connects to 4G every so often but is mostly just connecting to 3G/HSPA+.


I am on a LTE plan - so even when on 3G it's eating data, wouldn't be such an issue if on unlimited 3G I suppose.


All that said - pretty awesome phone!
