Like it or not, you're going to have a hard time escaping the clutches of landline internet data caps. Cox has expanded its trial 1TB data caps from Cleveland to include customers in Florida and Georgia. Once a two-bill grace period expires, you'll have to pay $10 for every 50GB of data you consume over the limit. You'll start getting warnings if you reach 85 percent of your cap. It's not clear if or when Cox will expand the trial or make it permanent, but it won't be shocking if it becomes a mainstay.
