Before You Buy a Smartphone in 2026: Locked In, Locked Out, or Unlocked

The iPhone 17 says from $899. The price with no carrier attached is $929. The trade-in credit pays out over 36 months, and only if you stay. Here's what to check before you buy a smartphone this year.

Quick Verdict

Compare the carrier price with the unlocked price, and do the math on leaving early. Skip any used phone whose seller can't show it erased and unlinked. Get the update end date in writing. If your phone still gets updates, waiting is an option, but forecasts show no early relief.

iPhone 17 From $899 Is Not the Price

Apple's iPhone 17 page says from $899.

Then the footnote.

That price includes a $30 connectivity discount that requires carrier activation. It's not available if you connect to a carrier later, or if you use a prepaid plan.

The unlocked iPhone 17 is $929.

Same phone. A different price depending on who you tell.

The price on the screen is the price if you do what the footnote says.

And the footnotes are getting more important. Phone prices moved twice in six weeks:

  • On September 9, Apple raised the iPhone 16, 17, 17e and Air by $100.
  • On October 1, Samsung raised the Galaxy S26 family by $100. Verizon, AT&T, T-Mobile and Best Buy matched it, according to WhistleOut. How-To Geek reports Samsung didn't officially explain why.

Counterpoint says global smartphone retail prices are up about 20 percent in 2026, and third-quarter shipments fell 20 percent from a year earlier. It calls that the weakest third quarter since 2012.

Here's where U.S. list prices landed in October:

Tier Phone Price
Value iPhone 17e $699 (was $599)
Value Galaxy S26 FE $699 (unchanged)
Mid iPhone 16 $799 (was $699)
Mid iPhone 17, 256GB $899 with carrier activation, $929 unlocked
Upper Galaxy S26, 256GB $999 (was $899)
Upper iPhone Air $1,099 (was $999)
Premium iPhone 18 Pro, 256GB $1,199
Premium Galaxy S26+, 256GB $1,199 (was $1,099)
Premium iPhone 18 Pro Max, 256GB $1,299
Premium Galaxy S26 Ultra, 256GB $1,399 (was $1,299)

The Galaxy S26 FE and the foldable Z Fold8, Z Fold8 Ultra and Z Flip8 kept their launch prices.

The Trade-In Credit Is Paid Monthly. Only If You Stay.

Every carrier ad for a flagship phone leads with a big number.

AT&T says up to $1,200. T-Mobile says up to $1,000. Verizon says up to $840.

Now read what the number is.

  • AT&T credits range from $350 to $1,200 and are applied as a monthly credit over a 36-month installment plan.
  • Verizon says the customer must remain in its Device Payment Program for 36 months.
  • T-Mobile pays an instant credit plus monthly credits over 24 or 36 months. It uses 36 months only on certain plans.

Apple's footnote adds that the trade-in value depends on condition, year and configuration, and not every device is eligible.

So the credit isn't cash at checkout. It's a bill credit that arrives a little each month.

Do the subtraction. If the credits are $840 over 36 months, that's $23.33 a month. Leave at month 18 and 18 credits never arrive. That's $420.

Leave at month 18 and you've paid for half of a discount you never got.

The calculator above runs this with your numbers. With the defaults, staying the whole term comes out $15 cheaper than buying unlocked. Leaving at month 18 comes out $135 more expensive.

Set the extra plan cost to zero and the carrier deal looks $555 better than unlocked. That's why that one input matters so much. Premium plans often cost more than the plan you have now.

One more detail. A carrier deal also needs an activation fee. AT&T and T-Mobile each list $35.

Samsung's $150 Credit You Can't Spend on the Phone

Samsung's S26 Ultra offer sounds simple. A $150 Samsung Credit with purchase.

Then you read where it works.

On Samsung's page, the credit can only be spent on:

  • Buds
  • Watches
  • Tablets
  • Select accessories
  • Samsung Care+

It says it can't be applied to the phone itself. It's valid October 9 through December 31, 2026.

That's a store credit. Not a discount.

Other Samsung promotions on its October page:

  • Galaxy S26 FE: up to $100 off through October 26
  • Galaxy Z Flip8: up to $150 off, October 9 to November 2
  • Galaxy Z Fold8 family: up to $200 off, October 12 to November 2

If you want the cash off the phone, read the line that says where the money goes.

A New Model Isn't Always a Safe Model: The iPhone 18 Pro Max on AT&T

Launch week is the most exciting time to buy. It's also the riskiest.

The iPhone 18 Pro and Pro Max were announced on September 9, 2026 and shipped September 18.

A week later, MacRumors reported that some U.S. iPhone 18 Pro Max owners had lost AT&T cellular service. An iOS 27.0.1 update didn't fix it. On October 3, Apple said the problem was hardware-related and that affected units can't be repaired and must be replaced.

We got that from Wikipedia, which cites MacRumors and Macworld. We couldn't open those reports. So treat the details as reported, not confirmed.

The lesson holds either way.

A brand-new phone from a brand-new line can arrive with a problem nobody has found yet. Your protection is the return window.

The habits that help:

  • Search the model name plus “recall” and “problem” before you buy.
  • Check the maker's support pages.
  • Test calls, data and charging on day one, on your carrier.

Used Phones: Locked to Someone Else

A used phone can look perfect and still be unusable.

Apple says an iPhone still linked to a previous owner's Apple Account can't be reactivated without that owner's password. A Locked to Owner screen means don't take ownership of it. And parts from a locked device aren't eligible for Apple warranty or AppleCare service.

Here's the test Apple describes:

  • Turn the phone on and run setup.
  • If a Locked to Owner screen appears, stop.
  • If setup asks for the previous owner's Apple Account, the phone is still linked.
  • Don't pay until the seller removes it from their account, which they can do in a browser.

Then the carrier side. Verizon's policy, updated February 18, 2026, says:

  • A financed phone unlocks when it's paid in full.
  • Paying with a Verizon gift card delays unlocking by 35 days.
  • A prepaid phone stays locked until 365 days of paid, active service.
  • A phone reported lost or stolen stays locked.

We couldn't retrieve AT&T's or T-Mobile's unlock rules. So ask the seller for the IMEI, and have the carrier confirm the phone is eligible for your account.

A used phone is only a deal if it works on your account.

How Many Years of Updates Does Your Phone Get?

A phone that stops getting security updates keeps working. It just stops being safe.

Phone What the maker says
Pixel 8 and later 7 years of OS and security updates, counted from when the model first launched on the Google Store
Galaxy S26 family Seven years, to 2033 (as reported on Wikipedia)
iPhone Apple doesn't publish a number. iOS 27 runs on the iPhone 11 and later

Read the Pixel line twice. The seven years count from the model's launch, not from the day you buy it. A Pixel bought a year after launch gets six.

Then the battery. Apple designs iPhone 14 and earlier to keep 80 percent capacity at 500 cycles. It designs iPhone 15 models for 1,000 cycles. Its warranty covers a defective battery.

On a used iPhone, 80 percent is the line. Apple's service threshold is 80 percent capacity. Worry if it's under that, or if the seller won't show it.

We couldn't retrieve Apple's or Samsung's battery replacement prices. Ask before you rely on a swap to save an old phone.

Return Windows for Phones Are Short and Have Fees

Seller Window for a phone Fees and catches
Best Buy 14 days for activatable devices. 30 days for Verizon-activated $45 restocking fee on opened, activated phones. None if unopened or bought in one of eight states (AL, CO, HI, IA, MS, OH, OK, SC). Opened SIM kits can't be returned
Target 14 days Restocking up to $35, none if unopened. Contract phones may carry early termination fees and go back in store. Circle Card adds 30 days
Costco 90 days Return details vary by carrier service contract
Apple 14 days From Apple's education terms. We couldn't open the consumer page. The 2025 holiday extension excluded carrier-financed iPhones
Walmart Wireless phones: 14 days, according to a search summary Opened unlocked phones may be exchange only. We couldn't read the page directly
Amazon 30 days for most items. Renewed: 90 days Wipe the phone first

One trap that doesn't show in a table. Returning a phone may not cancel your line. Apple's own holiday notice, as quoted in 2025 coverage, says returning an iPhone may not automatically cancel or reset your mobile account. So cancel the line yourself.

And use the window. In the first week:

  • Make calls on your carrier
  • Test the camera in low light
  • Charge it fully and run it down once
  • Check the eSIM or SIM transfer

Phone Insurance: What Each Plan Charges Per Claim

The monthly price isn't the whole story. The fee per claim is where the plan hurts.

Plan What it charges
AppleCare One $19.99 a month covers up to three products. $5.99 a month for each extra. $49.99 a month for a family of up to six
Apple claim fees Screen or back glass $29 to $99. Other iPhone damage $99. Theft or loss $149
Samsung Care+ $29 per cracked-screen claim, or $0 with the Theft and Loss version. Theft and loss deductible $99 to $199. Three lost or stolen claims per 12 months. A one-time payment covers 2 years
Verizon Mobile Protect Advertises $0 deductible cracked-screen repairs on select smartphones

We couldn't retrieve monthly prices for Samsung Care+ or the carrier plans. So ask before you assume.

The FTC says an extended plan isn't a good value if it doesn't offer more coverage than the warranty that came with the product. Apple's one-year warranty excludes accidents and liquid damage. So accident coverage is the part you'd be buying.

eSIM: Check Before You Switch

Many phones now have no SIM tray.

To move a line to a new iPhone, Apple says both phones must be:

  • Signed in to the same Apple Account
  • Unlocked
  • Nearby, with Bluetooth on
  • Running iOS 18.4 or later

Moving from an Android phone means contacting your carrier.

Before you buy, confirm that your carrier supports eSIM on the phone you picked. Apple lists eSIM-only models by region.

One more thing to watch. The iPhone 18 Pro's battery is listed at 4,056 mAh in the physical-SIM version and 4,288 mAh in the eSIM version, according to Wikipedia. Check which version you're buying.

We couldn't retrieve the FCC's SIM-swap rules. So set a carrier PIN on your account when you switch.

Spec Words That Cost You Money

On the box What it really means
Up to $X trade-in Usually bill credits over 24 or 36 months. Value depends on the condition, year and configuration of your old phone
0 percent APR for 36 months No interest, but the credits and the lock-in come with it
7 years of updates Counted from the model's launch. Check whether it's full OS updates or security patches only
mAh Battery size. Not comparable across brands. Galaxy S26: 4,300. S26+: 4,900. S26 Ultra: 5,000
Nits Brightness. Peak HDR is not everyday brightness. Wikipedia lists the S26 FE at about 1,900 nits and the other S26 models at about 2,600
Megapixels Resolution, not image quality
Optical zoom and digital zoom Optical uses lenses. Digital crops pixels
Unlocked Works on any carrier, subject to network band support. Apple says an unlocked phone stays unlocked
Galaxy AI free Samsung says basic features are free and that future releases may include paid features
Renewed, certified, refurbished Different programs with different warranty terms

Right to Repair for Phones

Smartphones are covered by right-to-repair laws in five states, for products first sold there on or after each effective date:

State When it starts
Minnesota July 1, 2024
California July 1, 2024. Parts for 3 years on products priced $50 to $99.99, and 7 years on products of $100 or more
Oregon January 1, 2025. Software parts-pairing ban for devices made after that date
Washington Key provisions January 1, 2026
Texas September 1, 2026 (House Bill 2963)

Nevada's law doesn't cover phones. Those dates come from Repair.org, an advocacy group.

Ask whether parts are available and whether parts pairing blocks a third-party repair.

Wikipedia says iFixit scored the iPhone 18 Pro 7 out of 10. We couldn't retrieve out-of-warranty repair prices.

Refurbished Phones and Gray-Market Imports

Apple's certified refurbished iPhones were:

  • iPhone 16, 128GB: $659
  • iPhone 16 Plus, 128GB: $749
  • iPhone 15 Pro, 128GB: $679
  • iPhone 15 Pro Max, 256GB: $849

Against a new iPhone 16 at $799, the refurbished 128GB is $140 less. That's 17.5 percent. We couldn't confirm the new phone's storage tier, so treat that as an estimate.

The cost is the update clock. iOS 27 still supports iPhone 11 and later. But a refurbished phone has used some of its years.

Our rule of thumb, not a law: buy refurbished from Apple or a certifier that names the warranty, and only if the discount is above about 15 percent.

Gray-market imports are a different animal. Samsung limits service for its phones to the country where they were first sold. A phone bought abroad may have no U.S. warranty service.

And skip the cheap charger. UL's 2018 test found more than 99 percent of 400 counterfeit iPhone adapters failed its safety tests. The consumer electronics guide covers charger and power bank recalls.

When to Buy a Smartphone

Treat the forecasts as forecasts.

  • Black Friday: November 27, 2026. Carrier deals mostly ride on credits, so read the trade-in section again.
  • Counterpoint: Conditions stay difficult for the rest of 2026. No meaningful recovery until component costs and supply improve.
  • How-To Geek, citing TrendForce: Memory prices aren't expected to fall until 2028. We couldn't confirm that at TrendForce.
  • Rumors: WhistleOut expects the base iPhone 18 in spring 2027 and the Pixel 12 in fall 2027. Those are expectations, not announcements.

The best time to buy is when your phone stops being safe or its battery gives out and you can't live with it.

The worst time is launch week of an all-new model. The iPhone 18 Pro Max on AT&T shows why.

The second worst time is any day a credit pushes you into 36 months you won't honor.

Who Should Buy Now, Wait, or Walk Away

Six rules. Each one comes from the numbers above.

  1. Buy now if your phone has lost security updates

    Or if the battery is failing and you can't wait. Prices are expected to stay high.

  2. Wait if your phone is supported and works

    A Pixel 8 or later has seven years. An iPhone 11 runs iOS 27. Waiting is an option, not a savings plan.

  3. Walk away from carrier deals that need a premium plan for 36 months

    Unless you're certain you'll stay. Run the calculator with your real plan prices.

  4. Walk away from any used phone that isn't erased and unlinked

    No Locked to Owner screen. No request for a previous Apple Account. No exceptions.

  5. Buy refurbished only from a certifier that names the warranty

    And only when the discount beats about 15 percent.

  6. Skip the insurance unless it beats your repair risk

    Compare the deductible plus the monthly cost against what a screen or battery repair would really cost you.

Frequently Asked Questions

Should I buy my phone unlocked or from my carrier?
Unlocked costs more up front but removes the 36-month credit lock. Apple's iPhone 17 is $929 unlocked or $899 with a $30 carrier-activation discount. Carrier credits depend on staying. Verizon requires 36 months in its payment program for the full benefit. Run the calculator with your own plan prices.
What happens to my trade-in credit if I switch carriers?
You lose the credits you haven't received yet. They're paid monthly over 24 or 36 months, so leaving at month 18 of 36 forfeits half. You also have to pay off the remaining phone balance. Verizon, AT&T and T-Mobile terms differ, so read the credit agreement before you sign.
How many years of updates will my phone get?
Google promises 7 years of OS and security updates for Pixel 8 and later, counted from when the model first launched on the Google Store. Samsung promises seven years for the Galaxy S26 line, to 2033. Apple doesn't publish a number, but iOS 27 supports the iPhone 11 from 2019.
Is phone insurance worth it?
Often not, unless it adds accident coverage your warranty lacks and the fees beat your repair risk. Apple's fees run $29 to $99 for screens and $149 for theft and loss. Samsung Care+ is $29 per screen claim with $99 to $199 for theft and loss. The FTC says a plan is poor value if it adds no coverage.
How do I avoid buying a stolen or locked used phone?
For an iPhone, run setup. A Locked to Owner screen or a request for the previous owner's Apple Account means walk away until the seller removes the device from their account. Ask the carrier to confirm the IMEI is clear. Verizon keeps reported lost or stolen phones locked.
Will phone prices fall soon?
Counterpoint says a meaningful recovery is unlikely until component costs and supply improve, and retail prices are already up about 20 percent in 2026. Samsung raised S26 prices on October 1 and Apple raised older iPhones on September 9. Expect promotions through credits more than lower sticker prices.
