Would she be able to see who I call?

So my mom is planning on getting me an iPhone, she said that I better not be going on anything I'm not suppose to because she has a parenting app where she can see things but she said she couldn't see my texts. So would she be able to see who I call and hear the conversation?

Nope

No she can't hear the conversation, but she may be able to see your call log because she is the one who pays the phone bill (at least for Sprint they do that). Only the number will show up tho, no names
