AT&T and Verizon started accepting pre-orders for the a few weeks ago. AT&T is pricing the 3G Samsung Gear S2 Classic at $250 with a 2-year service agreement, while Verizon has the wearable on sale at $350 on a 2-year contract or $400 outright. T-Mobile has yet to announce its pricing details.
On the software side, the Gear S2 Classic runs Samsung's own Tizen OS. However, aside from being fully compatible with Samsung's own Galaxy smartphones, the watch is also capable of syncing up with Android smartphones running Android 4.4 KitKat and up.
The processing power is drawn from a Qualcomm Snapdragon 400 chipset with a 1.2GHz dual-core CPU and 512MB of RAM. Other highlights include 4GB of internal storage space, a waterproof build and a programmable eSIM that allows you to switch carriers without swapping a physical SIM card.
