Sony’s Xperia Z Ultra has first appeared at the FCC on June 25 – the same day the handset was officially announced. However, that version did not have LTE.
Now, a new FCC filling is showing an Xperia Z Ultra with LTE – bands 2, 4, 5 and 7. Since it also has 1,700MHz HSPA connectivity, this version could be released by T-Mobile USA (which uses LTE band 4).
T-Mobile is already selling the slightly older (and smaller) Xperia Z, so it’s not that hard to believe that it wants to add more Sony handsets to its portfolio. Of course, until solid evidence on this shows up, the Xperia Z Ultra launch on T-Mobile remains just a supposition.
At only 6.5mm, the Xperia Z Ultra is the world’s slimmest Full HD smartphone. Or maybe we should call it phablet, since its display is a 6.4 inch one. Regardless of that, the Xperia Z Ultra is waterproof (IP58) and dustproof, and features: Android 4.2.2 Jelly Bean, NFC, 8MP rear camera, 2MP front-facing camera, quad-core Snapdragon 800 processor clocked at 2.2GHz, 2GB of RAM, 16GB of expandable internal memory, and a 3,050 mAh battery.
The Z Ultra is currently available only in South-East Asia, but it will make it to other markets starting the next few weeks.
