First he has test it out...be at the office around people she knows and then turn it off for 90 mins....then back on. Then when he goes home assess how she reacts, or whether she says anything. If so, the entire office can honestly vouch for him. That will unmask her surreptitious efforts as well.Tell him to turn it off when he hobbies and very quickly that will flush out: A) whether she's actively monitoring him; and B) whether this is really about her suspecting he's cheating. That fact that he hobbies probably means she already suspects.
Here's a much better piece of advice... stop letting your wife pick out your cell phone and run your tech life!
