I have had this smart watch for a while and knew that I could receive calls and dial out but could never get voice output to permit a communications with another. A few weeks and I think I noted this, I purchased another watch which was working great with my Samsung 7 phone. I noted that when called by someone else both watches would activate and one for sure I could treat as if it was a phone within itself. Today with a little help from a friend, I found that both watches would do the same thing, but of course WiFi can only communicate with one device at a time. Problem solved I have two smart watches and one dumb smart phone. Now I see a very suffocated, medically friendly smart watch is now on the marked from APPLE. I have not priced it yet I am sure it is equal to the cost of both of my watches together or well exceeds the price that I paid. Am I going to buy one, probably not I am not an APPLY supporter.
