My teenager is very tech savvy when it comes to his cell phone. I've noticed a drastic change in him lately. I want to read his text messages and replies without him having any idea that Mom is invading his privacy. Is there anyway to do this remotely to monitor his device without having to pay for it? I have an app for his Facebook messages but his text messages are always deleted. I don't want to break his trust but I need to make sure he is safe.
