I don't understand the logic behind AT&T and Verizon's pricing plans. When I was on T-Mobile, unlimited free SMS was included with the data plan I had, and it's the same on all of Sprint's contract plans that I'm aware of.
I suppose it's because the former two are the giant carriers here, and the latter two have to offer some compelling reasons to switch. With T-Mobile and now Sprint, I've enjoyed great customer service and pricing options that make sense to a data-heavy user like me. The only downside to either network is simply coverage, and both have improved greatly in that regard over the past few years.
