The Korea Herald says that Samsung Electronics and the South Korean Telecom are discussing a new Samsung Gear 2 smart-watch with standalone calling features - that is, phone calls with no pairing to a smartphone. Currently, the Galaxy Gear and the Gear 2 can make calls only while tethered to a Galaxy smartphone. The Gear 2 v2, however, will have a SIM-card (USIM) slot and 3G connectivity. Presumably, the South Korean carrier will lock it to its own network.
A representative of SK Telecom confirmed that the new Gear 2 will be initially released in Korea, but it's possible that it will reach global markets later. Meanwhile, the Samsung Gear 2, Gear 2 Neo, and Gear Fit will be up for sale in the coming weeks.
