As well as taking the wraps off the Galaxy Note 3 ahead of last year's IFA exhibition in Berlin, Samsung also introduced its inaugural smartwatch effort in the form of the Galaxy Gear. Sure, it was panned by critics and went down with consumers like the proverbial lead balloon, but it was a start, and having rolled out a handful of wearables since then, the company is in much better standing as far as the emerging smartwatch market is concerned. Given the Korean outfit's insatiable need to continually push new products, the rumor that another smartwatch may be rolled out alongside the Galaxy Note 4 at this year's IFA is none too surprising, and with the report on the matter also suggesting that it will include its very own SIM slot, it's perhaps the most interesting smartwatch that Samsung has brought to us so far.
