Just in addition, I just updated m U2 to the latest RC and it still shows SMS for my RCS contacts. Now, it would be interesting what would happen, when my watch is standalone and I’m writing him.
Is it relayed to my iPhone and then send as RCS or will it be sent by the internal eSIM as SMS. Since multicards here can’t send SMS and are being relayed by the iPhone (unless it is connected somewhere to the iCloud) it should work the same way for RCS.
Still wondering that this detail isn’t shown in the Watch messages app.
