Can i track text messages online with a verizion plan and an iPhone?

My son has an iphone 5s with Verizon services under my contract. Can i track the text message conversations online? Or is there an app for that? A app that is discrete that he would not know that its on there.

You seriously need to let him go. Even if there's a way, I hope no one tells you because that is simply not cool. If you really really need to be an over controlling parent then just read his texts when he goes to bed.

You could just ask him. Whenever my mom asked me to read my conversations I let her.
