Cox data cap in Tucson, AZ
Edited by John VollData checked
The data cap, in Cox's own words
Cox's data usage page says its residential internet plans include 1.25 TB (1,280 GB) of data a month, counting both downloads and uploads. The allowance resets with each monthly usage cycle, which runs on different dates from the bill.
The first time a household goes over, Cox applies a one-time courtesy credit for that cycle. After that it adds 50 GB blocks at $10 each, up to $100 in overage charges a month. Cox sells an Unlimited plan and a 500 GB Additional Data Plan for an additional monthly charge; its page does not list those prices.
ConnectAssist, Cox's low-income tier, also includes 1.25 TB, and Cox says it carries no data overage charges.

Cox's FCC broadband labels, in the last copy of its label file we hold (collected September 7, 2026): 9 of its 41 label plans list 1,280 GB a month; the rest do not state one.
What changed with Spectrum
Charter, the company behind Spectrum, closed its purchase of Cox in August 2026 and said it would bring Spectrum pricing and packaging to the Cox footprint by mid-September (Light Reading).
Cox's site now carries the Spectrum brand, and its page on adding data says that when you connect to Spectrum Internet, unlimited data is included, with no data caps or overage fees (cox.com).
Existing plans did not switch over on their own. A Spectrum spokesperson told Arizona customers that legacy Cox customers would see no changes to their current bills, products or services unless they chose to make changes (azfamily). Cox's data usage page still describes the allowance above, so a plan started with Cox can keep it until you change plans.
