Ok so I just got a brand new Z2 factory unlocked (D6503) 3 weeks ago. Since the model supports LTE I was happy to test it out.
The network operator I'm on has excellent coverage of 4G in my area and that 4G works on other devices well. Turns out that Z2 can search for the LTE network but gives the error of can't register the SIM or network is not available.
I have spent hours with customer service of my network, even got my SIM card changed and also got my 4G subscription deactived and activated on the handset. All other settings (APN etc) are configured ok.
I also changed my network operator with my father's on which 4G coverage is optimal (they're the government run organization), and even on that Z2 can't register on the LTE network.
I confirmed time and again that the bands broadcasted by the networks here are supported by Z2.
Then how come Z2 is not registering on working on LTE? Is this a software issue?
I'm on the very latest FW (.314) that is availble.
