AT&T Internet cancellation policy
Here's all the info you need to cancel your service, end it early, or return your equipment.
Cancellation policy
You may cancel your AT&T Internet service for any reason within 14 days of activation without paying an Early Termination Fee (ETF). You're responsible for all fees and charges incurred through cancellation and must return any leased equipment. If you cancel after 14 days and are subject to a term commitment, you must pay service fees and other charges incurred, including an ETF.

To cancel service:

• Be sure that the account owner calls us at 800.288.2020.
• Have the account number and personal identification number (PIN) on hand.
• Call during normal operating hours. Cancellation requests received when we are closed will be handled on the next regular business day.
Early termination policy
You'll be charged an Early Termination Fee (ETF) if you disconnect your AT&T Internet service more than 14 days after activation and you have a term commitment. The ETF is prorated and reduced for each month that your Internet service is active. The applicable ETF will appear on your bill as Early Termination Fee within 3 bill periods.

ETF example (amounts are estimates):
ETF is $180 and the term commitment is 12 months
