You're reporting being targeted by an immensely well-funded and sophisticated adversary, with tooling worth many millions of dollars, and particularly given successfully targeting your devices, your cellular carrier, and a business.
That means with that level of exploits and related exposure, you shouldn’t expect help in a forum. You’ve undoubtedly also already gotten all of the usual security advice from previous discussions too, and have considered and implemented that advice as appropriate. Which means you’ll be getting repeated suggestions in this and future posts, at best.
You’ll need to obtain more specialized forensics help or other reviews for whatever is or is not happening here, whether that assistance is security-related, or IT-related, or otherwise. Again, forum threads just won’t get you the help you need.
Given your reported multiple exploits over time and replacing devices due to whatever is happening here, probably best to move to a feature phone and other simplifications.
PS: I see nothing relevant in the analytics.
