Samsung's massive Galaxy Mega 6.3 is ready to make its U.S. debut, launching on AT&T, Sprint and US Cellular.

Samsung first unveiled its new Galaxy Mega series back in April, introducing two phablets: the Galaxy Mega 5.8 and the huge Galaxy Mega 6.3. While there's no word yet on the U.S. launch of the 5.8-inch model, the 6.3-inch one has already made its debut in some markets and the U.S. is apparently next on the list.

The Samsung Galaxy Mega 6.3 aims to give users the best of both worlds, allowing them to enjoy the more advanced functionality of a tablet while still providing the features and convenience of a smartphone.

"We continue to bring innovation with our Galaxy family of devices, with the Galaxy Mega representing a manifestation of consumers' enthusiasm for our thin, large screen designs," touts Nick DiCarlo, Samsung Mobile vice president of product planning and marketing, in the Aug. 19 press release.

"The Galaxy Mega combines exceptional features from the Samsung Galaxy smartphone family with a 6.3-inch screen, making it an optimal device for movies, books, music and games."

The Samsung Galaxy Mega 6.3 will launch in the U.S. in two available color options: Polaris White and Nova Black. According to the company, the phablet will make its debut on AT&T, Sprint and US Cellular starting later this month. Each carrier, however, will have to confirm their own release date, colors and pricing.

For those unfamiliar with this massive tablet, the Samsung Galaxy Mega 6.3 sports a 6.3-inch HD Super Clear LCD display with a resolution of 720 x 1280, a dual-core processor clocked at 1.7GHz and 1.5GB of RAM to keep things running smoothly. It will launch as a mid-range device running on Android 4.2.2 Jelly Bean.

Samsung will also be offering various accessories such as the Flip Cover, the S-View Flip Cover and Protective Cover+ for the phablet, but these accessories will be available separately.
