The major U.S. carriers all offer aggressive iPhone deals — typically bill credits applied over 24–36 months when you trade in a device and sign up for a qualifying unlimited plan. This covers current iPhone 17-series offers at Verizon, T-Mobile, and AT&T, plus the structural details that decide whether you actually save the advertised amount.
Verizon
Verizon's iPhone promos span 36 months and require Unlimited Ultimate for maximum savings. Its offers have gotten aggressive: iPhone 17 and 17 Pro are available at no cost with a new line on Ultimate; 17 Pro Max is up to $1,100 off with trade-in; iPhone Air up to $1,000 off; iPhone 17e free with a new line on any Unlimited plan. Lower tiers (Welcome, Plus) qualify for reduced credit. Upgrades require the trade-in phone active on the account for 60 days.
T-Mobile
T-Mobile applies credits over 24 months (shorter than Verizon) and accepts trade-ins in any condition. It has dropped the trade requirement on several models: iPhone 17 is free with a new line on Experience Beyond/More or Better Value — no trade needed; 17 Pro is free with trade + a qualifying Experience plan; 17 Pro Max up to $1,100 off; iPhone Air free with a new switch. Maximum discounts require Experience Beyond ($110/mo). Switchers get up to $800/line to cover ETFs via virtual prepaid Mastercard.
AT&T
AT&T applies credits over 36 months and accepts iPhone 13 and newer plus select Android. iPhone 17 / 17 Pro are free with eligible trade-in on qualifying unlimited plans; 17 Pro Max up to $1,100 off; iPhone Air up to $830 off; iPhone 17e at $4.73/mo with trade-in. Base trade credit starts on ~$50/mo unlimited plans; the maximum ($1,100) requires a higher-tier plan (Unlimited Premium, ~$70+/mo).
Carriers vs. buying from Apple
Buying direct from Apple gets you an unlocked phone free to move between carriers, prepaid services, and international SIMs. Apple's own trade-in values run lower than carrier promos (up to ~$700), but Apple Card Monthly Installments spread cost over 24 months at zero interest, and the iPhone Upgrade Program bundles AppleCare+ with a yearly upgrade after 12 payments. Go Apple if flexibility beats subsidy; go carrier if you'll genuinely stay 36 months on a qualifying plan anyway.
MVNOs play a different game: Visible pairs new lines with gift cards instead of bill credits, Boost runs aggressive no-trade-in discounts, Mint discounts phones with annual prepay, and the cable MVNOs (Xfinity, Spectrum) reserve their deepest cuts for internet customers. Smaller discounts — but no premium-plan requirement propping up the math.
How the deals actually work
- Bill credits, not upfront discounts — you finance full retail and the carrier offsets it monthly; net zero only if you finish the term.
- Trade-in valuation matters — the advertised max requires a current-gen flagship; get a real quote first.
- Plan tier requirements — max discounts always require the priciest unlimited plan; the plan cost is often the real cost.
- Early termination — cancel or downgrade and remaining credits forfeit; treat these as 24–36 month commitments.
- Switcher promos stack with trade-in — but usually arrive as virtual prepaid Mastercards, not bill credits.
Before you sign up
- Get your trade-in's exact credit value from the carrier's estimator — don't rely on advertised maximums.
- Add up the qualifying plan's cost over the full term.
- Read the fine print on financing, early termination, and auto-pay requirements.
- Confirm coverage at your address before committing.
- Ask your current carrier's retention line to match — unadvertised deals often beat public switcher promos.
