I have recently been through the same thing. Exactly.
However I managed to get this working.
For easier reference il add my full steps here:
I ordered the watch direct from Samsung so was not easy.
Once the watch arrived, this was set up like normal.
I knew I needed an Esim so after hours of looking and being told to go to the shop, found an easier way.
I called O2 on 202 (as I currently have a contract with o2) and asked could i set up a watch Esim.
This was £7 rolling contract
Once ordered, this popped up on the o2 app, I mistakenly clicked install. (do not do this as it installs to your current mobile, not the watch.
Go to MyO2 and under devices can select install new sim. This allows you to view the needed QR code. However if you do install it, just select, request new esim. Minutes later it appears as a QR code on your account.
Go to the watch and select add mobile data plan, scan the QR code and this is now linked
However!!! this also showed as emergency calls only.
The next step is what worked.
On your mobile, go to Call and text on other devices make sure this is on. However, my watch was NOT appearing. and still displaying as emergency calls only.
The trick now!
Open teh Wear app - Go to Watch Settings - Advanced Features - Remote connection - Call on other devices - Turn this on!
Once this is enabled on both the wear app aka the watch, and your phone. it works!
Hope this helps as seen allot of stick recently.
You do not need to go to a shop
You do need an Esim
You do Need call on other devices enabled on both
To verify, if you go back to the phone settings, search call & text on other devices. You should now see your watch appear here ready for usage.
