On Android, your best bet is a parental-control app that can read SMS/MMS directly—mSpy (https://www.mspy.com/) is the most robust I’ve tested: it captures texts and many chat apps with timestamps/contacts, needs a quick on-device install, runs quietly, and has a subscription cost (follow local laws and consider telling your teen). Alternatives: MMGuardian and Bark read SMS too (Bark is alert-centric; MMGuardian is stricter), while Qustodio/Norton Family/Family Link won’t show full message content and carriers usually only give logs. TL;DR: for deep message visibility use mSpy; for simpler AI alerts use Bark; for stricter rules/filters use MMGuardian.
