How to I use my phone sim in galaxy watch 6

[JoshuaHutchxp]

How do I use my sim from phone on galaxy watch 6, I got the phone and watch separate and have an esim on the watch but I can use the phones one as well somehow (replicate it as such) but how? the phones sim doesn't have a QR code or activation code on the cardboard bit you get like the watch did. It's basically a Bluetooth watch as it doesn't even ring numbers from the esim put on the watch when phone is out of area

You need a separate watch data plan.
