T-Mobile has entered the fray between its fellow largest carriers in the U.S. as the company announced on Monday that it will also start selling the T-Mobile Galaxy S III beginning on June 21.

Furthermore, it is now official that the Galaxy S III variants going to the four largest mobile carriers in the U.S. will all be powered by dual-core 1.5GHz S4 processors as T-Mobile has revealed that its T-Mobile Galaxy S III will also be powered by the QUALCOMM Snapdragon CPU.

The international version of the Samsung Galaxy S III is powered by the quad-core 1.4GHz Samsung Exynos 4212 processor.

However, unlike Verizon, AT&T and Sprint who also all announced their plans for their Galaxy S III smartphones on Monday, the Deutsche Telekom-owned company is keeping mum on the pricing of the T-Mobile Galaxy S III.

Verizon, AT&T and Sprint have said that their 16GB Galaxy S III units will start at $199.99. Verizon and Sprint have revealed that their 32GB versions will be priced at $249.99 while AT&T is promoting adding a $39 16GB microSD card for storage of 32GB selling for $238.99.

T-Mobile has revealed, however, that flavor of the Galaxy S III going to its network will also be powered by 2GB in RAM. This is the same amount of RAM as the units going to Verizon and Sprint. AT&T, on the other hand, did not reveal how much RAM will be powering its Galaxy S III offering. However, since Verizon’s, Sprint’s and T-Mobile’s units pack 2GB in RAM, it’s highly likely that the AT&T variant will also have 2GB in RAM.

However, AT&T and Sprint offer units which differentiate them from those offered by their competitors. AT&T has revealed that it will be the only national carrier in the U.S. which will offer a red variant of the Galaxy S III. Meanwhile, Sprint has revealed that the Galaxy S III smartphones going to them will have Google Wallet preinstalled out of the box.

All of the phones will be working on the 4G LTE networks of the four large carriers albeit the units going to Sprint will only be able to take advantage of the higher speed offered by 4G when Sprint launches its LTE network later this year. AT&T boasts that their 4G LTE network currently cover more than 260 million people in the U.S. and Verizon says that they will cover that very same number after they expand their LTE network from 258 to 400 markets this year. Meanwhile T-Mobile is boasting that they have “America’s Largest 4G Network.”

“We have a tremendous history of working with Samsung to bring cutting-edge devices to market, and we know our customers are excited to get their hands on the Galaxy S III,” said T-Mobile USA’s Brad Duea in a statement.

“As we continue to aggressively compete, this device is yet another example of how T-Mobile delivers amazing devices and 4G experiences to our customers,” the T-Mobile USA senior vice president for product management added.

As with the Galaxy S III versions announced on Verizon, AT&T and Sprint, the T-Mobile Galaxy S III will be powered by the latest Android mobile operating system: Android 4.0 Ice Cream Sandwich.

It will also feature the large 4.8-inch HD Super AMOLED screen (1,280×720 pixels – 720p resolution) of the international version of the device and its equally large 2,100mAh battery. For comparison, the Galaxy S II which is the predecessor of the Galaxy S II had a 4.3-inch Super AMOLED Plus screen – which some argue is better than the Super AMOLED display of the Galaxy S III because it has a full set of subpixels – with a resolution of 800×400 pixels and a 1,650mAh battery.

The T-Mobile Galaxy S III will also feature an 8MP rear camera which has Burst Shot and Best shot and is capable of capturing Full HD 1080p video and a 1.9MP front camera.

T-Mobile wants to differentiate the T-Mobile Galaxy S III from the offerings of its rivals by appealing to people who may want to use their smartphone for business. The company said in its release:

“For customers who want to use the device in their business and personal lives, T-Mobile’s Galaxy S III offers a suite of security features delivering enterprise-friendly capabilities. From syncing corporate email, calendars and contacts to providing on-device encryption, the Galaxy S III makes it easy to maximize efficiency and productivity for enterprise users. T-Mobile customers also have access to Wi-Fi Calling and the Smartphone Mobile HotSpot feature ensuring easy and reliable connectivity while on the road.”

The T-Mobile Galaxy S III will also feature the same software features of the Galaxy S III international version which we discussed here in-depth.

To be released on June 21 will be the “metallic blue” and “ceramic white” versions of the T-Mobile Galaxy S III although the carrier did not say when it will start taking preorders through its stores and through its website.
