A:AnswerHey, Badal, this is a great question! I would suggest reaching out to your regional support for warranty information. International warranty works differently. Their customer service number is 1800 3000 8282
and 1800 266 8282.
A:AnswerNo, the watch does not have the option for a SIM card. You have to buy the watch with cell service built in. At this point there are only two, AT&T and I think Verizon. Those versions of watches are also about $200 more. Hope this helps.
A:AnswerI have this watch for about 18 months, already I'm looking for battery replacement.
It used to have 50% left at the end of my day and now it barely gets through the day before going to low power mode.
There are you tube videos on how to replace the battery
A:AnswerFrom the literature I have it appears you can get a number issued to your Samsung Smartwatch so you don't have to worry about having your phone nearby
A:AnswerIf you want cellular connectivity on this smartwatch then you will need to get the AT&T version. You would have to add the watch to your AT&T plan if you already have one.
Otherwise, you will have to establish an AT&T plan. The alternative is to have the AT&T version without any plan or smartphone, and it will operate as just a smartwatch without any of the features that require connectivity (TEXT, EMail, Calls...). (I think setup may require a connection of some kind though.)
