You sound like my grandfather when he had a phone. Constantly switched off and only switched it on when he wanted to call somebody and then switched it off. So frustrating how he was incapable of understanding that other people might want to call him too.
I do this at home to avoid needlessly hunting for towers that are barely in range. But I am concerned that if I don't leave the house for a few days the carrier (Google Fi / TMobile) may be discarding messages. I've heard mixed opinions on if this is happening. But I am missing calls even with WiFi calling on.
But how can you be surprised that other people don't do this if you expect to be able to call them? If you are able to call them, they have to have their phone not in airplane mode, right? Or do you only do scheduled calls?
So basically your system only works for you, because if all those people you might call did the same thing, the chances of you both checking your phones and trying to call at the same time are very low.
It's a mobile network terminal and camera that I occasionally use to place calls to businesses, after all. The business can leave a voicemail if they need to reach me. My family and friends can send written messages. I don't see the issue.
