Two Samsung Gear S2 versions stop by the FCC, no cellular radio in sight
Although the FCC listings don't tell us too much about the SM-R720 and the SM-R732, they do reveal that neither of these devices will come with cellular connectivity. Instead, they will use the more traditional connectivity option (for a smartwatch, at least), which is pairing up with a smartphone through Wi-Fi or Bluetooth.
If you're into the design of the Samsung Gear S2 but really want a stand-alone smartwatch that can place calls directly from your wrist or browse the web without relying on a connected smartphone, a tiny glimmer of hope still exists. Previous information suggested that Samsung is actually working on three separate versions. The one that is missing from the recently-discovered FCC listings will allegedly bear the model number SM-R730, and this might be the version that brings the often-rumored cellular radio.
