Question: Issues with push notifications with no cell signal when on WiFi?


I seem to be having real issues getting WhatsApp message alerts (and the messages themselves) when my screen is off. I have WiFi but I am pretty sure when I unlocked the phone it takes a few seconds for the WiFi icon to come up. It’s like th WiFi is going off when the screen is off.

Problem is I have no signal so only WiFi call at home. I read someone that the WiFi does sleep with the screen off and reverts to cell data? Is this true, because that ***** and means I can’t get notifications!! What’s the point of WiFi?

Be grateful if any help...

Even more stupid, my work iPhone sat in my house - tried to use find my iPhone but it has no cell signal.

Doesn't make any sound until I wake it up, and then try to browse the internet - this is crazy Apple, what gives? Never had this issue on my Android device, push notifications just work because WiFi stays on like it should.

Plus, my iPhone 7 sat here with the screen off but power connected - unable to ping the device, the moment I wake it I can. Interesting this time though as WiFi calling was running, so maybe its doing what I think they do and routing data via the "cell" connection.

I am wondering if it's when the WiFi calling gets dropped and the WiFi doesn't then come back on...?

Would be nice to hear from Apple what the "expected behaviour" is!
