The nation’s largest cable company has decided to charge $30 to let customers bypass Comcast’s (CMCSA) data limit of 300GB per month, Ars Technica reports.

The company has been experimenting with data caps in nine different states. When customers exceed 300GB, they have to pay $10 for each additional 50GB, although they are given three months of leeway before they are penalized.

Comcast recently decided to test an unlimited data option in a few Florida locations — Fort Lauderdale, the Keys, and Miami. Customers in these areas can choose to pay an extra $30 per month to stop worrying about going over their limit. If they end up using less than 300GB, they will not be reimbursed. The additional charge is only worth it for customers who tend to use more than 450GB each month.
