> don't really want to provide no cost authentication for other entities Is the customer not paying for the cell phone plan? Nothing is “no cost” in this situation.

Or, if T-Mobile and others did a good job in security for their networks and in turn their customers communications maybe they wouldn’t have this issue. IMO this comparison would be like claiming a gas station is responsible for your cars electronics not functioning properly.
