I think having phone data is still necessary. Even though many places offer free wifi, many of them are not secure connections. I love having data on my phone. I can use my phone as a hotspot wherever I go to and still have a secure connection. I recently learned that I really do not need to have the internet at home anymore. With my cell phone provider I can stream video through Netflix, Hulu, etc using my phone as a hot spot, and it does not use any of my data.
