Samsung Gear 2 (available since April)
Unlike Samsung’s previous smartwatches (Gear Live, Gear 2, or Galaxy Gear), the Gear Solo will support SIM cards, thus being able to make calls by itself - so users won’t need to pair it with a smartphone. With that in mind, we assume that this smartwatch will be a bit more expensive than the current models. Reportedly, the Gear Solo will be showcased on September 4, despite the fact that the Galaxy Note 4 is expected to be announced one day earlier, on September 3.
It’s not clear if the Gear Solo runs Tizen OS (like the Gear 2), or Android Wear (like the Gear Live). We also don’t know what to expect when it comes to design, but it’s hard to believe that the Gear Solo won’t resemble Samsung’s other smartwatches. Anyway, it’s said that the new wearable device will have 3G connectivity, but no LTE support. We'll bring more on this as soon as new info is available.
