I recently upgraded a Gear S2 to a new Active 2. With the Gear S2, if I was connected remotely to the phone, if a call was received on the phone, my watch would also ring too and I could answer the call on the watch. With the new Active 2, if connected remotely, the watch never rings when the phone receives a call. If I don't answer the call on the phone, then the watch does receive a missed call message, so there is some communication going on between them.
That is also borne out by the fact that any texts sent to the phone will appear on the watch and any texts sent form the watch appear on the conversation history on the phone and the recipient sees that the text came from my cell phone number, unless the watch us in standalone mode. In which case the sending number is that of the watch. (I have an older wearables plan, rather than a digits line, so separate phone numbers for the watch and the phone).
The watch can make and receive calls using it's own number when in standalone, so cellular service is up and running.
Everything works as expected if the phone and watch are connected via BT.
The cell phone is a Note 9 running PIE.
