The ASUS PadFone X is officially set to go up for pre-order in the U.S. next month, as AT&T will start offering the device.

ASUS announced this smartphone/tablet combo a while back and it will finally hit the U.S. soon, priced at $199 on a standard two-year contract with AT&T. Starting on June 6, interested buyers will be able to book the ASUS PadFone X through AT&T's online or retail stores.

For those who prefer not to commit to lengthy carrier agreements, meanwhile, AT&T will also be offering the ASUS PadFone X with no annual contracts through the Next 8 and Next 12 programs, with prices starting at $22.92 and $29.80 per month, respectively.

ASUS took the wraps off its PadFone X smartphone/tablet hybrid back in January at the International CES 2014. AT&T grabbed the exclusive rights to offer the device in the U.S., but other than revealing the main specs and features the carrier failed to offer any details regarding availability so far.

AT&T has now released pricing details for the ASUS PadFone X and revealed that it will start taking pre-orders for the device next week, but it still failed to mention just when the smartphone/tablet combo will actually become available. The carrier may offer an exact launch date once pre-orders go live.

As a reminder, the ASUS PadFone X consists of a smartphone and a tablet dock. The smartphone packs all of the major components, while the dock features a larger display and an extra battery to turn the device into a tablet.

The device sports 5-inch 1080p display as a smartphone and a 9-inch 1200p screen as a tablet, and packs a quad-core Qualcomm Snapdragon 800 processor clocked at 2.3GHz, 2GB of RAM, and 16GB of internal storage capacity under the hood. Connectivity options include Wi-Fi 802.11 a/b/g/n/ac, Buetooth 4.0, GPS, and 4G LTE. The smartphone has a 2,300 mAh battery, while the tablet has a larger 4,990 mAh unit.

AT&T is also offering a promotional deal on PadFone X accessories, selling the two-pack tablet cover, wireless charging folio, and Duracell wireless charging mat for $80 after a $50 discount.
