Any way to save text messages to computer?

My son doesn't have a smartphone (Android, iPhone, Windows) and I want to see who he's been text messaging. He deletes his text messages quite often, is there anyway I can secretly have his text messages start saving onto my computer?

Secretly? No. You would have to have something installed on it to CC you a message, or you'd have to take it and actually offload the messages to PC before deletion. But if you are the account owner, then your itemized bill will show the numbers exchanging texts, just not the contents. That info is stored on the cellular network's servers and could be obtained, just not sure how lengthy a process that would be for you. But software does exist you can use. Best luck.
