I'm on my 2nd watch now and still am unable to get a cellular connection. I troubleshot for 3 days with technicians over the phone to the point they told me it was defective and just take it in for another one so I did that and am having the same issue. Took it into a store and their tech guy had no idea how the watch worked, he even tried using the Samsung gear app to change the settings for the watch. The watch shows as activated on my account but in the SIM status it shows my network state as Disconnected.
