I have an unlocked "T-mobile" iPhone 6, model A1549. Next month I'm visiting Japan and the Philippines, and I'm trying to figure out if I'll be able to get away with pre-paid SIM cards or if I'm going to have to lug around rented Wi-Fi hotspots.
According to Apple, it won't work in either places.

But according to this list:
http://en.wikipedia.org/wiki/List_of_LTE_networks#Asia
It seems that at least some bands are supported, like au does bands 1 and 18, Docomo does 1 and 19, and Softbank does 1 as well. In the Phillipines things look a little better with all three of Smart's bands (5,3,1) showing up as supported.
If that's the case then I'm confused why Apple only lists the A1586 as being compatible with the Philippines. Can anyone with more experience chime in?
