Samsung's Galaxy Note 2 has become immensely popular, especially in China, that its maker caved in to demands voiced out by Chinese consumers - a dual-SIM version of the world's first commercially successful smartphone-tablet hybrid.

The Note 2 will soon join the slew of dual-SIM handsets flooding the Chinese mobile market as Samsung formally announced the commercial release of the phablet that accommodates two different telco services simultaneously.

Citing reports from Intomobile, UK-based PhonesReview said on Monday that the dual-SIM Galaxy Note 2 will hit store shelves in China beginning Dec 3 and the handset will work both on GSM and CDMA networks.

Buyers will be able to insert two SIMs on the new Note 2 China-version, the report said, as Samsung redesigned the gadget to make room for two SIM slots that accept a regular SIM and its micro-sized version.

This new hybrid device will be priced at over $US900 and will have the familiar specs that pleased global consumers since its release two months ago.

That means no compromise on the manner that the Note 2 gained worldwide following as Samsung made sure that the handset will carry the following specs: 5.5-inch 720p Super AMOLED touch screen, an 8MP rear camera and 2MP front snapper and a 1.6GHz quad-core processor paired with 2GB of RAM.

This Note 2 version is expected to further ramp up the smartphone's global sales, which Samsung said already clocked more than five million units sales after only 60 days of availability, further strengthening its position of soon eclipsing the stellar performance of its predecessor.

The South Korean firm is upbeat that soon enough the Samsung phablet will eventually reach 20 million hands the world over, a feat that CNET said is highly possible owing to Samsung's partnership with 260 telcos in countries around the world.

Analysts, however, are in doubt if the Note 2 will equal the other Galaxy bestseller, the S3, which already sold 30 million units since it was pushed out by Samsung in the second quarter of 2012.

Together, the two Samsung Galaxy handsets are tipped by research firms to power the Asian tech giant's total smartphone sales for Q4 2012 beyond the 60-million mark, a spectre that likely will put Samsung again on top of the global smartphone war, notwithstanding the recent issuance of Apple's iPhone 5.
