The mobile carrier battle stateside might really get heated up soon enough, based on a couple of fresh new reports. On one hand, we have an absolute newcomer ready to ambitiously hit the market, while on the other there’s a little guy who’s clearly looking to expand.

The little guy is MetroPCS, a telecommunications provider that services around 9 million tech users in the States right now, being way behind Verizon, AT&T, Sprint, T-Mobile and even TracFone when talking about the number of subscribers.

A certain “beast” you might have heard of quite a bit could however help MetroPCS boost its numbers over the next few months, having now been confirmed as hitting the regional carrier. The Samsung Galaxy S3 won’t be the only new phone to be released by MetroPCS this fall, but will certainly capture the spotlight.

According to Sascha Segan from PC Magazine, who has managed to get some one-on-one time with the new super-phone, this looks and acts pretty much identical to Sprint’s version of the S3. There isn’t much pre-installed “crapware” and the LTE speeds are quite impressive, according to the tech journalist.

In terms of hardware, MetroPCS’ Galaxy S3 won’t have the opportunity to set itself apart from other US versions of the super-phone and will be equipped with the exact same 1.5 GHz dual-core processor and 2 GB of RAM. Then again, what more could you ask for?

Aside from the star, MetroPCS has teased three more modest phones expected to hit the carrier this fall. There’s one more Samsung device, as well as two unnamed Coolpad and ZTE handhelds. The Samsung highly resembles the Galaxy Mini, but is a riddle for me, as it was nowhere to be found in that leaked roadmap from a few weeks ago.

There were two Sammy phones there aside from the S3, but the Galaxy S Lightray 4G has already been launched, while the Contour 2 simply doesn’t fit the bill. That will most likely be a follow-up to the 2010 Contour, which was a very basic clamshell phone.

The mysterious Coolpad and ZTE phones teased by MetroPCS appeared in the July leak, so they aren’t that mysterious after all. The Coolpad Quattro 4G is rumored to be coming by the end of August with Android 2.3 Gingerbread, LTE speeds, a 4-inch WVGA display, 1 GHz processor and 5 MP rear-facing camera.

As for ZTE’s handheld, it’s supposedly called the “Anthem” and might be released in early September. Aside from sporting 4G LTE speeds, the Anthem doesn’t have any more specs revealed, but hopefully we will find out all there is to know about it in a couple of weeks tops.

Oddly enough, MetroPCS didn’t tease the Huawei Verge, Pinnacle 2 or Samsung Contour 2, three other phones expected to see the light of day by the end of September. This could mean the trio got canceled, never existed in the lineup, or will come later than expected.

Who’s excited about the Galaxy S3 for MetroPCS? How about that Galaxy Mini lookalike? Or maybe the Coolpad Quattro 4G has caught your eye. Let us know by dropping a comment below.
