I have tried nokia 520 and nokia 925 with windows 8.1 and microsoft 532 with windows 10... and people come occasionally to me with windows phones unable to connect... and I see that people wordwide are complaining about that... also, it appears that it works in some places, but with crippled configuration...
and remeber, android and iphone work with no problems... and I have never seen any windows phone working on that network... go figure...
