More about Sprint cutting off its neediest customers:
The Washington Post reports the 1,000 customers that Sprint dumped averaged 25 calls a month to customer service over the past six to 12 months. Some called more than 300 times a month.
According to Roger Entner, a senior vice president at IAG Research, it costs phone companies $2 to $3 a minute to provide customer service, so after 8 to 12 minutes a month, they make no profit from a customer.
But according to ZDNet blogger Russell Shaw, 200 of the canceled accounts belonged to members of the military, who were sent the "Dear John" letters because of "excessive roaming."
