Save 20% Per Line With AT&T’s Group and Community Discounts

AT&T offers a 20% discount on eligible plans to several groups, all valid through Jan. 1, 2027:

• Employees and group members: Save 20% per line if your employer or organization participates in AT&T’s signature program.
• Military personnel: Active duty, veterans and their families save up to 20%.
• First responders: Police, firefighters, EMTs and paramedics save up to 20%.

New Phone Deals: Save Up to $1,800 at AT&T

AT&T’s current phone promotions run through Aug. 25, 2026, and most require an eligible trade-in and a qualifying unlimited plan unless noted:

• iPhone 17 Pro Max: Save up to $1,100.
• Samsung Galaxy S26 Ultra: Save up to $1,100.
• iPhone Air: Save up to $700.
• iPhone 17e: $0 with an eligible trade-in.
• Samsung Galaxy S26+: $0 with an eligible trade-in.
• Multi-device bundle: Save up to $1,800 when you buy an iPhone, iPad and Apple Watch together.
• Any smartphone: $50 off, no trade-in required.
• Per line: Get up to $800 off per line when you add a new line.

Trade-in values depend on your current device’s condition and model, so your actual savings may land below the maximum advertised discount. Check your specific device’s trade-in value before you commit to a plan.

Bundle Wireless and Home Internet to Save Up to $420 a Year

Combine an eligible AT&T wireless plan with AT&T home internet, and you’ll save up to $420 a year on your combined bill, valid through Aug. 25, 2026. The discount applies automatically once both services are active on your account.

Try AT&T Free for 30 Days

New to AT&T? Test the network with a free 30-day wireless trial, valid through Sept. 15, 2026, before committing to a full plan. It’s a low-risk way to check coverage and call quality in your specific area.

Editor’s Take

If you qualify for one of the 20% community discounts, apply it before shopping for a phone deal. It stacks with your plan every month going forward, unlike the phone trade-in promotions below, which are one-time savings tied to a single purchase. Very good.

On the phone deals, don’t assume the advertised maximum applies to you. The $1,100 and $1,800 figures depend on trading in a specific device in good condition — check your exact trade-in value on AT&T’s site before you calculate your real out-of-pocket cost. Good, but confirm your trade-in value first.

AT&T Wireless FAQs

How do I get AT&T’s military, teacher or first responder discount?

Verify your eligibility through AT&T’s online signup process or at an AT&T store. Once verified, the 20% discount applies to your account automatically for as long as you remain eligible.

Do I need a trade-in to get AT&T’s phone deals?

Most of the deepest discounts, including the $1,100 off iPhone 17 Pro Max and Galaxy S26 Ultra offers, require an eligible trade-in and a qualifying unlimited plan. The $50 off smartphone offer doesn’t require a trade-in.

Can I combine a community discount with a phone trade-in deal?

Yes. The 20% community discounts apply to your monthly plan cost, while phone trade-in deals apply to your device purchase. These are separate discounts and can generally be used together.

How much can I save by bundling wireless and home internet?

Up to $420 a year when you combine an eligible AT&T wireless plan with AT&T home internet. The discount applies automatically once both services are active on your account.

Is there a way to try AT&T before switching?

Yes. New customers can try AT&T’s wireless network free for 30 days before committing to a full plan.
