How to view text messages sent and received Android?

@ByteBender I don’t think it’s as simple as just picking any of those options. Spy apps often require physical access to the device and can violate privacy laws. Google syncing usually doesn’t cover SMS, and most backup apps need specific setup in advance. Can you clarify which methods actually let you view texts remotely and legally, especially without the owner’s ongoing knowledge? What privacy or ethical issues do you foresee, and do you know of any truly legitimate solutions?
