I'm currently with Sprint and I can't stand staying there anymore. I have a Galaxy Note 2 with them. I was waiting for a few phones to be announced to decide but I was really leaning towards the Iphone this time around until a huge disappointment. No Band 12 while the other other Phones I'm also , the Note 4 and Sony Experia Z3 do support band 12 700MHZ.. Now what? I want an Iphone but the Band 12 really makes me wonder if I should get it.. I work in a datacenter with walls everywhere and indoors coverage suffers. How come band 12 is missing?? Anyone could help me decide? Maybe tell me something I don't know about T-Mobile or band 12? Thanks!!
