It may not cost much to the industry, but it also isn't very profitable in comparison to many other things either. US mobile carriers generally don't have a good public image but everyone uses them anyways since there's only a few major ones and a smaller amount of MVNOs that run on the major carrier networks. But back to why they don't do it voluntarily: It's not profitable enough for them to consider making the changes necessary to it, and PR isn't a major concern either, so it won't be done unless it becomes legally required.
