A second Japanese carrier has announced plans to launch the Sony Xperia Z4. au by KDDI confirmed that it will be stocking the Xperia Z4 (SOV31) and Xperia Z4 Tablet (SOT31). This follows NTT docomo who announced earlier in the week that it will carry three new handsets this summer: the Xperia A4 (SO-04G), Xperia Z4 (SO-03G) and Xperia Z4 Tablet (SO-05G).
au by KDDI will launch the Xperia Z4 in four colours in mid-June (Aqua Green, Black, Copper and White) and the Xperia Z4 Tablet in mid-July in two colours (Black and White). So that is two Japanese carriers who have announced the Xperia Z4 series. SoftBank could potentially also announce the handset, it will hold a press conference on 19 May 2015. However, we know most readers want to know when it hits western markets, Sony remains tight-lipped on that front but we would hope further information is coming soon.
