Do I need to turn off WiFi on my phone before I go out in order for my watch to make or accept a call? --- Post Merged, Sep 25, 2017 --- I also missed a call & it didn't ring on my watch. My S2 always rang when I got a call. And of course this watch is cellular so it should have rung. Are there any settings to change on my phone or watch to send or receive calls on cellular?
