Early reports of a Sony Xperia Z3 supporting T-Mobile specific 700MHz band 12 LTE were brought to light a few weeks ago when the device (D6603) passed through the FCC. Although a pretty good indication of where the device could be headed, it wasn’t enough to make any strong conclusions.
For those that needed further confirmation that the Xperia Z3 will soon make its home on T-Mobile, some all new testing reports were recently published, showing — wouldn’t you know it — further support for T-Mobile’s network. Everything from 850MHz (3G/4G band 5), to 1900MHz (band 2) and 1700/2100 MHz (band 4) were all present, as well as the previously mentioned LTE 700MHz (band 12), 1900MHz (band 2), 1700/2100 MHz (band 4). So what does this tell us? Well, the specific combination of frequencies in question helps fill in some of the holes from the previous report and leads us to believe there is a damn good chance the phone is being tested on T-Mobile’s network.
So far, it seems every major US carrier missed the chance to offer the Sony Xperia Z2 on their networks although it’s still rumored to launch on Verizon Wireless later this year. With T-Mobile possibly being one of the few carriers to offer the new version (which is rumored to carry very similar in specs to the original), the Uncarrier is looking better all the time.
