Meet your expert

Hi, I'm Trent, a Coupons.com editor with more than four years of experience finding ways to cut bills at AT&T. I didn't need a new phone, but just to test it, I wanted to see how much money I could theoretically save with a trade in. When I negotiated with my current phone, I confirmed with a representative that I could've knocked over $900 off a new phone if I wanted to buy one.

About AT&T Fiber

AT&T sells internet, mobile, TV, and home security packages. The biggest consistent savings come from bundling services together.

For questions on existing service, call 800-288-2020. To activate a new fiber account, call 866-861-6075.

Trade in your old phone

Trading in an old phone can cut hundreds off a new one, but only when you follow their guidelines. Here's how it works:

  1. Buy a new phone on an installment plan, or upgrade a line with a qualifying plan.

  2. Trade in an eligible device and mail it for evaluation.

  3. Credits apply to your monthly bill over 36 months, not as an upfront discount.

Phones valued at $180 or more unlock the top trade-in credits. Before sending yours in, check resale prices on Swappa or Facebook Marketplace, where used iPhones often sell for $100 to $300 more than carrier trade-in value. Trade-ins make the most sense for phones that are cracked, very old, or hard to sell privately.

Refer a friend

Both you and your friend get bill credits, worth up to $50 off when you refer them to AT&T Fiber. But they must specifically use your referral link for the both of you to get a discount. If you don't see your credit, it's because your friend hasn't yet clicked your link. Have them open the link before completing signup or the credit won't post.

Get money back with AT&T points

The AT&T Points Plus Card is another one of our favorite options for consistent members. We know what you're thinking. Annual fees and extra fees is no good, but thankfully, you won't have to worry about that. With no annual fee and a $100 bonus after spending $1000 in the first three months, it’s a solid deal.

Plus, you'll earn something called ThankYou points on gas, groceries, and more. We recommend getting in touch with Citi when you want to cancel the card. You can contact AT&T Fiber directly, but calling Citi removes that one extra step.

Frequently asked questions about AT&T Fiber

AT&T Points Plus Card

The AT&T points plus card is for anyone looking for a consistent cash back on a new credit card. If you're already content with the cash back you get with a credit card, this isn't for you. Their card offers:

  • $100 bonus after you spend $1000 in the first three months

  • No annual fee

  • A flat 2% cash back rate

  • $10 per line monthly discount on your wireless or internet bills

After the first three months, you can get up to $20 in cash back each month, as long as you spend $1000 per month.

Bundle fiber and wireless for 20% off

Existing customers who already pay for fiber and wireless service can combine their accounts to save up to 20% on monthly bills. This works best for households already paying for both services. Here's an example of how much you could save:

  • Initially spending $50 per month for the Fiber 1 Gig (1,000 Mbps) plan

  • Initially paying $75 per month for the Unlimited Extra 2.0 wireless plan

  • Pay just $99 when you bundle the two services together

Where you were initially paying over $120 per month for both fiber & wireless service, you can now cut that by up to 20% off.

20% off military discount

Veterans, active duty members, and their families get 20% off unlimited plans. New customers can sign up on the Military and Veteran discounts page on AT&T's site. Existing customers should call 800-331-0500 to switch their plan over, which usually takes a few minutes.
