Verizon Unveils Wireless Plans That Cover Several Devices - NYTimes.com

This is an oligopoly domain begging for disruptive competition

"Customers who choose a shared data plan will pay a monthly fee for each device on their account. A smartphone would cost $40 a month, a normal cellphone $30 and a tablet $10. Then there is an additional monthly fee for the shared data pool, ranging from $50 for 1 gigabyte to $100 for 10 gigabytes. A family of three with an iPhone, a regular cellphone and an iPad that wants 10 gigabytes would pay a total of $180 a month.
When an account is close to using up its data, each device on the shared plan receives an alert asking if the customer wants to buy an extra 2 gigabytes of data for $10, Ms. Raney of Verizon said. But if they ignore this and go over the limit, they have to pay $15 for every extra gigabyte they use, she said."
