I bought my wife a Galaxy Smartwatch, and I have paired it. Whilst she doesn't want it for the phone function, I presumed that for it to work I'd need to get an esim. However I called my wife's phone number and the watch responded to the incoming call giving the option to answer or end.
My question is, how did it do it without a sim? And second question will it cost extra to answer or make calls on that device?
Thanks in advance
