Details on the Samsung Gear S2, a smartwatch expected to take on the Apple Watch were earlier disclosed revealing that it would come with a round design and will be available in various versions.

Now, iOL Mobile noted that a version of the watch will have its own SIM card, enabling users of the device to call without using a mobile phone.

Ars Technica added that this 3G version of the watch will also allow users to "access certain apps without the need to tether your smartphone."

It added that the 3G watch, as well as the non-3G version, will have features like Wi-Fi, Bluetooth 4.1 and NFC, which can be used for Samsung Pay.

In describing this additional feature, Reuters said Samsung Pay is a technology that "allows customers to pay for goods by simply placing their handsets on or next to a point-of-sale terminal."

Other important features of the device, as per TechTimes, is its circular face which measures 1.2 inches. It also sports a Super AMOLED display with a 360x360 resolution.

"One of the biggest highlights of the Gear S2 is the rotating bezel, a feature so simple and so necessary it could serve as a turning point in smart watch navigation. Moving beyond the bad pun, it could be akin to the iPod's scroll wheel," added the same report.

In a review, The Verge detailed that the rotating bezel of the watch has a great use.

"Samsung has basically added a free control dial to its watch, which dramatically improves usability," added the same report.

It also highlighted that the rotating bezel is perfect since it has the "right amount of resistance" for scrolling applications.

Revealed at the IFA 2015 in Berlin, the Samsung Gear S2 also has a dual-core, 1 GHz clock, 4GB storage space and 512GB RAM. Other useful features of the smartwatch are the accelerometer, ambient light sensor, barometer, gyroscope and heart rate sensors.

TechTimes said many users would love using this watch because it can last for 2 days without recharging and there is also an option to charges it "wirelessly."

In a news.com.au report, Samsung Electronics Australia vice-president Phil Newton mentioned that this new device from the company was made just like "a typical timepiece" instead of more complicated models.

"It looks and feels like a watch. You can control the product with a dial that's just like a traditional watch," Newton added.

Overall, The Verge noted that the Gear S2 has a lot of potential compared to the previous release.
