New Comcast innovation: A $30 charge to eliminate your data cap

Comcast has unveiled a new $30 charge that will let customers in Florida escape the company's 300GB monthly usage limit.

The nation's largest cable company has been trialling data caps in nine states, with slightly different policies in each one. Generally, customers who exceed a monthly limit pay an extra $10 for each additional 50GB, though customers are allowed to exceed the caps for three months before getting penalized.

But customers in Fort Lauderdale, the Keys, and Miami, Florida, can now purchase unlimited data for an extra $30 per month. Paying this additional $30 eliminates the 300GB monthly cap, but customers have to pay the extra amount each month even if they use less than 300GB.
