Hello, my wife's changing platform - it's a jump from WP to Android. Long story short - choice of handsets is between Honor 9 and Xiaomi mi 6. I'd prefer the latter (Xiaomi) but main question is - what about second sim card? One of the most important features is dual-sim. Primary SIM would be on Three so there shouldn't be a problem with LTE (apart maybe from travelling to Highlands, heard - even though 4G still works - is not as good as on models working on 800 and not 850), my only question is second sim. It's gonna be from polish mobile network (Orange), no need for data or LTE or 4G, it's just for texts and phone calls. Would it work ok? On frequency check it 's not showing 2g or 2.5G under "Three". Do I presume correctly that second SIM would work (on stand-by) in 2G mode only and therefor it's a no for Three network? Thanks for help.
