Cutting your phone bill might be easier than you think this month. AT&T is running strong offers across the board, whether you’re switching carriers, upgrading your phone or adding a line for the family. Switch, and you could get up to $800 to pay off your old phone, or trade in a device and save up to $1,100 on the latest iPhone or Galaxy.

Below, we’ve rounded up AT&T’s best wireless deals right now, from free phones to savings for students, teachers, military members and first responders. We’ll also walk you through how each one works and what you need to qualify.

Try AT&T Wireless Free for 30 Days

AT&T is letting new users try its network free for 30 days, through September 15, 2026. There’s no credit card required to sign up, and you keep your current phone, number and service the whole time. The trial runs on an eSIM, so you can switch between AT&T and your existing service to compare speed, coverage and reliability without committing to a new provider.

The trial comes with generous perks:

• 100GB of data
• 25GB of personal hotspot data
• Unlimited talk and text across the U.S., Canada and Mexico
• Unlimited texting to more than 200 countries
• Full access to AT&T’s 5G network

Because you get the full 5G network for the entire 30 days, you’re testing the real product, not a stripped-down version.

To sign up, all you need is your own iPhone. It has to be unlocked and eSIM-capable, and if you want to test the 5G network, it needs to be 5G-capable, meaning an iPhone 12 or newer. Once you’ve confirmed your phone qualifies, create a profile and activate your trial eSIM through the AT&T app.

Android users can’t take advantage of this offer yet, but AT&T says support is coming soon.

Switch to AT&T and Get Up to $800 to Pay Off Your Old Phone

Switching from another carrier? AT&T will give you a Visa reward card worth up to $800 per line—on up to 10 lines—to help pay off what you still owe on your old phone, through August 25, 2026. It’s one of the best switching deals around, especially for families moving several lines at once.

A few things to know:

• The card matches what you still owe, up to $800. If you owe less, you get less.
• To qualify, port your number to a new AT&T postpaid line. You also need to have been with your old carrier for at least 120 days.
• The card isn’t automatic. Upload your latest bill at att.com/switcherpayoff within 60 days of signing up, and the card arrives in eight to 10 weeks.
• If you cancel the line early, AT&T can take back some or all of the card’s value.

Get a New Phone for $0 With No Trade-In Required

You can get a new phone from AT&T for as little as $0 a month, and you don’t have to trade in your old one. Right now, that includes the iPhone 17e and the Samsung Galaxy S26+, both free, through August 25, 2026, while other models run from about $3 to $16 a month.

The way it works is simple. You pay for the phone in 36 monthly installments, and AT&T gives you a credit each month to cover part or all of the cost. On the free phones, that credit cancels your whole payment, so you pay nothing. On the rest, it just brings the monthly price down.

Before you sign up, keep two things in mind. You’ll need to keep your line active for all three years, because if you cancel early, the credits stop and you’ll owe whatever’s left on the phone. There’s also a $35 setup fee, plus taxes.

Trade In Your Phone for Up to $1,100 Off the iPhone 17 Pro Max or Galaxy S26 Ultra

Trade in an eligible phone and you can save up to $1,100 on either the iPhone 17 Pro Max or the Samsung Galaxy S26 Ultra, through August 25, 2026.

The savings come as monthly bill credits spread over 36 months, which bring the phone’s monthly price down. The Galaxy S26 Ultra drops from $36.12 a month to $5.56, and the iPhone 17 Pro Max goes from $33.34 to $2.78.

To qualify, you’ll need an eligible trade-in and an eligible AT&T unlimited plan. The exact credit you get each month depends on which phone you trade in and which plan you’re on.

Save Up to $1,800 on an iPhone, iPad and Apple Watch Bundle

Buying into the Apple ecosystem? AT&T is currently offering up to $1,800 in combined savings when you buy an eligible iPhone, iPad and Apple Watch together, through August 25, 2026. Savings apply as bill credits spread across your installment plan, similar to the individual phone deals above, so the exact monthly breakdown depends on which specific models you choose.

Bundle Wireless and Internet for $30 a Month, Plus a $200 Reward Card

Pair an eligible wireless plan with AT&T Fiber and you’ll get 1-GIG internet speed for $30 a month for your first 12 months—a savings of up to $420 over the year. If you’re a new residential Fiber customer on 1-GIG or 5-GIG service, you can also earn a $200 reward card. Just remember to redeem it within 75 days of getting the reward notification, since it doesn’t arrive automatically.

Qualifying is flexible. New customers can sign up for both plans together, current wireless customers can add internet, and current internet customers can add wireless. Either way, you get AT&T coverage at home and on the go.

Save Up to 20% With AT&T’s Appreciation Discount

AT&T offers discounts to people who have served their communities, including military members and veterans, retired law enforcement officers, retired firefighters and teachers. The savings apply to AT&T’s three unlimited phone plans, from the entry-level Value 2.0 up to the top-tier Premium 2.0, and how much you save depends on which one you’re on:

• 20% off Premium 2.0
• 15% off Extra 2.0
• 10% off Value 2.0

To claim the discount, verify your eligibility on the AT&T portal and keep an eligible plan active on your account. The savings then show up as a bill credit within three billing cycles. You’ll need to recertify your eligibility once a year to keep it.

Get FirstNet Access for First Responders, Plus 20% Off for Their Family

FirstNet is AT&T’s network built just for first responders, public safety workers and eligible healthcare workers. Because it’s separate from the regular network, your service keeps working even when everyone else’s slows down during busy times. It also costs less than a standard plan, starting at $45 a month and going up to $72, depending on which plan you pick. All you need is a phone that works with FirstNet.

The savings cover your family too. Anyone on your account can get a discount on their regular AT&T plan, all on the same bill:

• 20% off Premium 2.0
• 15% off Extra 2.0
• 10% off Value 2.0

You can also mix FirstNet and regular plans on one account, up to 20 lines total, and more than one first responder in the same home can share it.

Save 20% on AT&T Premium 2.0 With the Student Discount

College students can save 20% per line on AT&T’s Premium 2.0 plan. Note that this deal applies only to Premium 2.0, not the Extra or Value plans, and you may get extra perks on top depending on your school.

To claim it, verify your student status on the AT&T verification portal by entering some details about yourself and your school. Once you’re verified, the credit shows up within three billing cycles.
