Setting up LTE mobile plan on Galaxy watch 6

[Pitos]

I recently switched from Pixel LTE Watch to Galaxy Watch 6 LTE version. However, I kept a Google Pixel 6 phone. One of the EE technicians confirmed that the LTE version of the watch works with Samsung phones only. 

I had this error message "EE doesn't offer mobile plans for your watch"

Strangely, I didn't see any small print saying that the LTE version is compatible with Samsung phones only.

I found this article, but clearly says that I can "...activate the mobile network only when you use a phone running the Android operating system 5.0 or later and with 1.5GB of RAM or more".

Is it possible that this requirement is imposed by the carrier, not Samsung?

This is really interesting but I haven't got a solution. But I'd love to know if you do find one
