Phone calls on the none 3g model?

Anyone knows if it will be possible to make or take calls on the none 3g version when tethered to a phone?
I think the first generation gear s was able to do that but I can't find any information on the gear s2.
All the reviews mention that the 3g version is able to make calls when NOT tethered to a phone, no mention about the none 3g version when it is tethered to a phone.
