Ok guys , hope I make sense here. Activated my cellular on EE this evening. All sorted & activated within about 2 mins. Just a question about what comes through & what wont. Now as an experiment I turned my phone totally off. When I did my watched switched over to my home WiFi network as it should’ve done. My wife called me from her mobile & the home phone & as expected my watch rang. Perfect. I then turned my WiFi off to experiment if out somewhere & no WiFi. As soon as I did the EE reception kicked in (good signal). My wife called from both phones again & again rang each time. Perfect. I then kept WiFi off & remained on Cellular & my wife sent iMessage & WhatsApp. The iMessage came through (perfect) , but the WhatsApp didn’t. I then turned WiFi back on & wife sent iMessage & WhatsApp. Again the iMessage came through no problem (Perfect), but the WhatsApp didn’t. So do I conclude from this , that if i want WhatsApp messages to come through when I don’t have my phone with me , my phone needs to be switched on still to receive WhatsApp messages wherever I am ? If this is correct behaviour , why is this different to iMessages ? Cheers for clarification guys. I’m new to Apple Watch Cellular & just working it all out.
