Galaxy watch SM R805 esim question

I am new to all this stuff
I have some problem to connect iphone to ESIM, I have found workaround by using esim configuration with galaxy phone, and then moving to iphone, the problem is that after doing so the iphone application doesn’t connect to watch, but esim works.
So the question is - is it possible to type esim number ICCID manually ? after doing full reset and connect application to iphone ?

There is no way to set ICCID number manually.
I think this link will help you.
