Deleting iPhone 4S messages forever?

So my mom is really suspicious of me and I admit, I have been sneaky. I don't want her seeing my texts. She said she would have my dad call the company and show her a list of the messages I've Texted since I've gotten this phone. Can she see my texts another way? How can I permanently delete messages so they don't show up on a bill or something.

RELAAAAAAAAAAAAAAAAAX…
our phone bill just show the bill summary i.e how many texts and how many call we made and received and all. Its doesn't content of text or conversation. Just delete those text from phone once, switchd it off and switch it on again just to make sure its showing any text.else for the safer side instead of your dad take a frnd with you and go to the apple store and delete it from the memory,

BTW what's wrong with you mum? She don't trust you?

I don't think people can just "request" a list of text messages from the phone company. If ATT (or whatever you carrier is) kept a log of all of the texts people send all over the US, they would need millions of gigabytes of storage. Just think. 300 million people, send an average of at least 15 texts per day?

Don't worry. Just delete the suspicious ones.

DON'T delete All of your texts though. If they take your phone and see you have not sent a single text ever, that is going to be a bit fishy.

Good luck!

Oh. And don't keep anything serious from your parents. They will find out whatever it is. And they will find out at a time most inconveienent!
