You can check mobile phone history by installing mobile phone spy software.
Can I check my girlfriend's cell call history from a lap top?
Why would you even want to do that? If you don't trust her, then obviously she's not the one for you, or you're one very insecure person. If you did that to me, you wouldn't have a girlfriend anymore. Just ask her what you want to know.
With Bitwar Data Recovery you can recover the call records she deleted
