My service provider is with Fido and their LTE network supports band 4(2100MHz) and band 7(2600MHz). I have a LTE sim card activated and 3G/HSPA works fine on it except LTE. I've checked cellular towers within my area and all the towers have these 2 frequencies of band 4 and 7. My phone is Xperia Z C6603 and it has LTE bands of LTE_BC1, LTE_BC3, LTE_BC5, LTE_BC7, LTE_BC8, LTE_BC20.
Now the problem is when I try to select any LTE network modes from entering *#*#4636#*#*, I'll automatically lose reception with the red X symbol and no data. Originally I thought I had to switch radio bands because Euro band is 2600MHz but I just realized that I got this phone from sister who got it from Hong Kong.
Could this be a region locked issue? Where Sony eliminated unnecessary bands that Hong Kong wouldn't use because of different network? So would this also mean that my phone doesn't actually have LTE band 4 and 7 so I'll have to enable them somehow? Would I be able to reset it to default radio band? Or what is the default?
This LTE coverage website: http://developer.sonymobile.com/2013/01/24/lte-coverage-for-xperia-smartphones/
is outdated from January 24, 2013. Canada has Xperia Z now so how would I go about in changing to Canada region? And would this help me get LTE?
edit1: so apparently each frequency NEEDS a physical, corresponding antenna to work. I'm assuming Sony wanted to save on costs so Hong Kong Xperia Z phones could be missing few antennas that would've worked with band 4 and 7 frequencies? Is there a way to find out about this?
