I have tried some apps (LTE Discovey, Cell Mapper i.e.), but always N/A. For Samsung just dial *#0011# . Thanks.
LTE band 1(2100), 2(1900), 3(1800), 4(1700/2100), 5(850), 7(2600), 8(900), 12(700), 13(700), 17(700), 19(800), 20(800), 26(850), 28(700), 29(700), 32(1500), 38(2600), 39(1900), 40(2300), 41(2500) - F8331, F8332
Hi @57,
Do you mean which frequencies your XZ Supports, or which ones you have an active connection towards? My initial thought was to post the LTE Bands which are supported for the different models of XZ which @uliwooly did, but if you could clarify what you mean that would make it easier for me to assist you. 
Hi!
I knew about the spec of the phone already. I would like to know what Band and Frequency that my phone is connecting.Like Samsung, when we press *#001# the Band and Freguency will show (please see the attached and hope you understand my point).
