The successor to the Lumia 1320 would have support for LTE-A and would have already passed FCC certification

There are more and more clues to the imminent appearance of a successor to the Lumia 1320 Before we already told you that this supposed phone would carry a 5.7-inch HD screen, 32 GB internal memory expandable via SD, 1 GB of RAM, a Snapdragon 400 processor, and what is most interesting of all: 2 cameras, rear and front, 14 and 5 megapixels respectively.
And now we find out that this model, officially named as RM-1062, would have already passed the certification of the FCC, the United States regulatory body responsible for approving all devices sold or manufactured in that country.
The data from this certification confirm almost all the specifications revealed before, but also realize that there would be another variant of this equipment, with a different model number, which would have support for LTE-Advanced (or LTE-A) connectivity, which would allow you to access browsing speeds up to 4 times higher than conventional LTE in places where this type of network is operating (such like some cities in Spain).
And along with information from the FCC, we also have leaked photos of what would be the case of this device, with the Microsoft branding on the back. In these images, the size of said casing is compared with that of a Lumia 535, thanks to which it is clearly appreciated that the diagonal of this case is around 6 inches.
So far everything indicates that this mid-range phablet would be presented at the Mobile World Congress in Barcelona, during the month of March . But considering that the equipment has already passed FCC certification and that there is rarely much time between that approval and the official announcements (example 1, example 2), it could be the case that the Lumia 1330 is presented before MWC, either taking advantage of an instance like CES (which will take place in a few days), or the Windows 10 event on January 21, or even being announced without there being an associated event, as was the case with the Lumia 535.
