Cancellation guide

How to cancel AT&T

A clear, step-by-step guide to cancelling your AT&T mobile, plus the things worth checking before you leave.

Before you cancel

You may be in a minimum contract, so leaving early can trigger an early-exit charge. Ask for the exact figure before you agree to anything.
Expect to be offered a retention discount or loyalty deal to make you stay. If you're sure you want to cancel, stand your ground.
Cancel before your next renewal date to avoid being charged for another period.
Cancel from the account you actually pay with, and make sure you're the billing owner before you start.
Always get your cancellation confirmed in writing and keep it.

Before you cancel, note that any remaining device installment balance becomes due immediately on your final bill when you cancel the linked line.
To cancel wireless service or remove a line, choose Chat when available or call AT&T on 800.331.0500.
Illinois, Massachusetts and New York only: if you ordered the service online, you may be able to cancel it yourself by signing in at att.com. Everywhere else, use Chat or phone.
Cancelling mid-cycle is NOT prorated, you are responsible for the entire bill period regardless of your cancel date.
Ask for and keep a cancellation confirmation.

Early-exit charge: Smartphones from ~$325, prorated −$10/full month served; other devices from ~$150 −$4/month. None if cancelled within first 14 days.
