We recently reported the Sony Xperia Z Ultra would be the first smartphone to come with octo-band LTE, allowing it to be used around the world and run on almost every open band available.
One problem with octo-band technology is it will not run on some carrier specific LTE bands. In the US, AT&T, Verizon Wireless and Sprint all have these carrier specific LTE bands. If the Xperia Z Ultra was to come to the US, it would need special LTE capabilities.
This is exactly what Sony is trying to do, with a new FCC filing showing the Xperia Z Ultra with compatible LTE brands for America. Initially the understanding was this would only be available for AT&T, but it will also work on T-Mobile.
The C6806 model will be the Sony Xperia Z Ultra in North America, we may see it come to Canada as well, since they have picked up the Galaxy Mega, another huge device. Rogers Wireless seems like the carrier to go to at the moment for large devices.
The LTE version will come at $199 on contract, it is one of Sony’s most premium and expensive devices to build, with the Snapdragon 800 processor, 6.4-inch 1080p display and 3050mAh battery.
Leakers are still unsure about US carrier availability, some say it will come on AT&T, but that would trump recent rumours that said no Sony device would be coming to AT&T for the next few months. We may see it end up unlocked on Negri Electronics or another unlocked seller website.
