Maya's Mission is the latest and greatest in the Comms genre, super high quality.
As for SAO it isn't really open world in playstyle it just has a big map. The phone will always tell you where to go and where she is, honestly the only missable stuff really is when she gets quarantined and you have to remember to check the security cameras between every break when you are at work.
Nebel Geisterjäger also has some good comms like stuff. It is a mix of heartrate monitor, phone calls, and security footage. Not exactly comms but close enough. I would also recommend anything from Kegani Laboratory, again not exactly comms but in real time girl status updates is something widespread in those games. They are grindy as fuck though so use cheatengine to cheat your ass off.
