I don't like Mint because it is gimicky ie: introductory rates, and you have to remember to commit to a new X month contract every X months. Use Ting's billing

I don't like Mint because it is gimicky ie: introductory rates, and you have to remember to commit to a new X month contract every X months. Use Ting's billing estimator to look at what your real usage is and see what it would cost. The real sweet spot is if you have multiple lines with medium usage since they pool usage and you aren't paying for an "unlimited" plan for multiple lines.
