RED Hydrogen One Holographic Phone Hits The FCC Ahead Of AT&T, Verizon Launch
Some additional details about the phone were gleaned from the FCC's report including the fact that the device supports all current U.S. wireless carrier LTE bands (with the exception of T-Mobile's Band 71) and that it has a relatively large 4,510 mAh battery. It also has dual SIM slots, which are popular with international travelers.

Powering the smartphone is a Qualcomm Snapdragon 835 processor, which was all the rage with the 2017 class of flagship Android smartphones. It will also include a 5.7-inch (2560x1440) display that can show off four-view holographic images. This feature is supposed to present "better than 3D" images to the user.
“There is no way to describe this," said RED back in May. "You just have to see it. So far, everyone that has seen it gasps, swears or just grins. I wish we had recorded all the reactions. Priceless."

The preorder phase for the Hydrogen One has passed, but the phone was available for $1,195 for the aluminum model, while $1,595 would get you a snazzy titanium body. However, AT&T and Verizon Wireless earlier this year stepped up and announced that they both will be carrying the phone when it launches this summer.
We'd have to imagine that going the carrier route will be more appealing to customers as they won't have to fork over so much money at once. That is especially pertinent given that RED is an unknown quantity with respect to smartphones.
