Thank ya.

This sore spot of the phone messages and the static world state stuck out to me during P5 from the way the cell phone is used.
You don't often get calls except after an SL level up in P5. Compare this to something like Cyberpunk where you are getting calls and texts from characters all the time, discussing many different things.

You should get calls a lot more often depending on the person/meeting and what time of day it is. Important meetings should be delivered with a call that must be replied to immediately.
You should also receive emails or social media notifications or something. Something to differentiate and filter between the SL's/jobs and the other information and lore that you want to present.
It's not reinventing any wheel, it's simple iterations. A deeper and more holistic clock that is tied with the phone would absolutely lend itself to the themes of the series.
