Correct. Neither do you. In fact it could cost them much less what they're charging customers for and hence seeing a tidy increase in profit. What's a decent profit? I'd wager that Randall Stephenson's idea of a decent or fair profit is much much different than yours or mine.AT&T is, and has been, slowly forcing their "average" customer to purchase more data than they need by increasing the lowest rate plan (and complaining about people using too much data at the same time). Their happy medium is having 20 million customers paying for 3 gbs of data and using 350 mb. Instead of charging a fair rate for data usage.
That's how business works. Lock the customer up and extract as much money from them as possible. They care not one bit about the customer other than as piggy bank.
A decent profit often depends on the bias a person has about the company involved.
A lot of people in here have no issues with Apple pulling in record profits. Yet, they often expect cell carriers to operate to break even.
And unlike Apple, AT&T has to play in a competitive market for iPhone customers.
