@johnr - i did google for VoLTE and there is too much of technical info. now i am even more confused. will you be able to tell me if i will get the LTE option on my N7105 ever. even if i have to wait for 4g to be available in nz or change carrier in future?
This is an oversimplification, but essentially the menu that you're looking at is the voice network menu. LTE is data-only at this stage. You don't see LTE in there for the same reason that you don't see HSPA.
Krishant007: Oh ok. So that means that none of the N7100 that is available via the NZ shops are the DC versions. That is, Bond and Bond, Noel Leeming and other retailers selling the phones are selling the non DC versions?
