Samsung wearable app still maintains that use can use your mobile device with one of the watches ( as you can see I have alot of time on my hands since becoming disabled 🤣🤣 ).
The definition shows that a tablet is a mobile device ( mine has a Sim tariff etc )
BUT and this is a BIG BUT, Samsung have removed this feature without warning on the app or website ( from what I can see ) and I have seen alot of people complaining.
