I just got my first iPhone today. It's the 4S. I had to get the 300MB data plan because it's all I can currently afford. I will mainly use data with wifi. My question: Are text messages included in the "Cellular Network Data" counter? Right now my "Sent" data is showing 131KB and my "Received" is showing 295KB I haven't gone online at all with my iPhone so I am just wondering what it could be from. I don't want to accidentally exceed my limit without even going online. I have used no apps that connect to the internet. All I have done is some texting and a phone call.
