I'm after a bit of advice if anyone can help. I want a high-end/spec dual SIM smartphone that will work over here in UK..(work and personal lines as is common I'm sure!). I want it to work on dual standby mode, preferably take a micro 128Gb SDXC too and have all other standard smartphone functionality. Cost is not a major issue as I'll try to get my company to pay! Can anyone help as it seems like a maze of issues reading research?!....largely it appears to do with which networks support which band frequencies as many are made for Asia and also i find it amazing that the major UK networks don't sell any of these dual SIM smartphones or poss 1. I heard there is a Samsung Note 4 model called Duos but not for sale over here that might work which would seem perfect....I want to probably use Three network for personal and maybe also for work and would be great to not have to the standard carry 2 phones option! Thank u all in advance!
