You're not a data driven trainer ... yet.
You can actually turn the data off and it will still work. I have an old phone that doesn't have service that I use to track my rides so my actual phone doesn't die. Of course I wind up carrying 2 phones, but I don't have to worry about having a dead phone 20 miles from home either.
