The state of smartphone shopping in the US
Americans replace their phones every two to three years, and the price of flagships keeps climbing. A premium iPhone or Galaxy can rival a laptop in cost. That reality has pushed millions of shoppers toward installment options that once lived only in carrier stores. Today, buy now, pay later (BNPL) services like Affirm, Klarna, and Afterpay have expanded far beyond fashion and furniture. They now sit right next to credit cards at checkout for phones sold by Apple, Samsung, Best Buy, and major retailers.
Carriers have their own long-standing plans. Verizon, AT&T, and T-Mobile all offer 24- or 36-month device installment agreements with 0% APR for well-qualified customers, spreading the full price of the phone across monthly bills. T-Mobile even introduced an Equipment Installment Plan Flex option that lets customers finance a new iPhone, including taxes and fees, over 36 months. These are not new concepts, but the way people compare them has changed. Shoppers no longer ask only "which phone?" They ask "how should I pay?"
That question matters because not every BNPL offer is the same. Some charge interest after a promotional window, some require a down payment, and others quietly add service fees. The good news is that the US market now offers enough variety that almost any buyer can find a plan that fits their budget and credit profile.
Comparing the main payment paths
| Payment option | Typical terms | APR | Best for | Trade-in value | Flexibility |
|---|
| Carrier installment (Verizon, AT&T, T-Mobile) | 24-36 months, billed on monthly statement | 0% for well-qualified buyers | Existing customers who want one bill | Often boosted by carrier credits | Locked to carrier until paid off |
| Apple Card Monthly Installments | 24 months at checkout | 0% APR | Apple shoppers with an Apple Card | Combined with trade-in at purchase | Can be used with any carrier |
| Affirm | Biweekly or monthly plans | 0% to 36% depending on the offer | Online shoppers at Apple, Amazon, Samsung | Varies by merchant | Pay over 4, 6, or 12+ payments |
| Klarna | Pay in 4 or monthly financing | Often 0% on shorter terms | Quick online checkout | Varies by merchant | No impact on credit score to check |
| Best Buy Financing | Monthly plans on eligible Samsung devices | 0% with approved credit | Samsung buyers avoiding carrier contracts | Applied at purchase | Not tied to a wireless plan |
Carrier installment plans
The classic route. You pick a phone, sign an installment agreement, and the device cost lands on your carrier bill each month. AT&T, for example, recently offered Galaxy Z Fold8 as low as $5.56 per month with an eligible trade-in, after credits applied over 36 months. Verizon and T-Mobile run similar promotions around new iPhone and Galaxy launches. The catch is the commitment: the phone is typically locked to that carrier until you finish paying it off, and leaving early means settling the remaining balance. For shoppers who already love their carrier, this remains the most straightforward path to a premium phone.
Apple Card Monthly Installments
Apple's own financing option keeps things simple. Choose Apple Card Monthly Installments at checkout, spread the cost over up to 24 months at 0% APR, and earn 3% Daily Cash back on the purchase. You can also combine it with a trade-in, which lowers the monthly amount. Because the financing is tied to your Apple Card, it works with any carrier, and there are no extra fees or hidden charges. The catch is eligibility: you need an Apple Card, and approval depends on your credit profile.
Affirm and Klarna at online checkout
This is where buy now, pay later gets interesting. When you shop for a phone on Apple's site, Amazon, or Samsung's store, you might see Affirm or Klarna as a payment option. Affirm offers 0% APR for 24 months on iPhones at Apple, with no late fees and no impact on your credit score just to check eligibility. Klarna lets you split payments into four installments or choose longer monthly plans, often with 0% APR on shorter terms.
These services appeal to shoppers who want the same convenience as a credit card without the revolving balance. The application takes minutes, decisions come back instantly, and you know exactly what you owe before you commit. Just read the terms carefully: longer-term plans can carry interest rates that vary by offer, and some providers charge service fees on certain transactions.
Best Buy and retailer financing
Retailers have gotten into the game too. Best Buy offers financing on eligible smartphones, including monthly payment options on Samsung Galaxy devices, with 0% interest for approved applicants on promotional terms. Buying unlocked through a retailer gives you the freedom to switch carriers anytime, but you will likely pay the full retail price unless you catch a sale.
Real-world scenarios and practical solutions
The student upgrading on a budget
Marcus, a college student in Austin, needed a new phone for classes but had no credit history to speak of. His credit card limit barely covered groceries. Instead of a carrier plan that required a qualified credit check, he used Klarna's pay-in-four option at a major retailer for a mid-range Galaxy model. Four equal payments, no interest, and the phone arrived before his first payment was due. The key was choosing a phone priced low enough that the four installments stayed within his part-time job budget.
The family buying three phones at once
A family in Ohio faced a common dilemma: two teenagers and one parent all needed upgrades in the same year. Buying three phones outright would have drained their savings. They went with a carrier family plan and spread all three devices across a single 36-month installment agreement at 0% APR. By trading in three older phones, they trimmed the monthly device cost considerably. One predictable bill, no interest, and each phone unlocked after the term ends.
The professional who wants a flagship without the contract
Sarah, a real estate agent in Denver, wanted the latest iPhone Pro for client photos but disliked being locked to a carrier. She bought the phone unlocked from Apple, used Apple Card Monthly Installments to split the cost over 24 months at 0% APR, and traded in her older iPhone to lower the monthly payment. She kept her existing prepaid service plan, which cost far less than a postpaid carrier plan. Total out-of-pocket cost per month was lower than any carrier option she compared.
A step-by-step action guide
- Set a realistic monthly budget. Decide what you can comfortably pay each month before looking at phones. This number will tell you which financing path makes sense.
- Check your trade-in value first. Old phones are worth real money. Carriers and retailers regularly advertise credits that can reduce a $58-per-month phone to single digits after trade-in. Check your device's trade-in value on the retailer's site before you commit.
- Compare total cost, not just the monthly payment. A $20-per-month payment over 36 months costs more than a $30-per-month payment over 24 months. Always multiply the monthly amount by the number of payments.
- Read the interest terms. 0% APR promotions are common but not universal. If a plan charges interest, calculate what the phone truly costs over the full term.
- Verify BNPL eligibility without hurting your credit. Services like Affirm and Klarna let you check eligibility with a soft inquiry, which does not affect your credit score. Use this to compare offers side by side.
- Watch for fees. Most major BNPL providers charge no late fees, but some shorter-term plans include service fees. The full cost is disclosed before you confirm, so review that screen carefully.
- Buy unlocked if you value flexibility. Unlocked phones work with any carrier, which is ideal if you switch providers or travel internationally. Financing an unlocked phone through a retailer or Apple keeps your options open.
Regional resources across the US
Shopping habits vary by region, and local options can make a difference. In Texas, carrier stores in Houston and Dallas frequently run trade-in promotions tied to new flagship launches, and chains like Best Buy offer in-store BNPL checkout for Samsung devices. West Coast shoppers in California can take advantage of Apple's financing options directly at Apple Stores, where staff will compare carrier deals and trade-in credits on the spot. Northeast buyers in the New York metro area often lean on unlocked purchases and retailer financing, given the density of prepaid carriers like Metro by T-Mobile and Cricket.
The bottom line
Buy now pay later smartphone plans have turned a big-ticket purchase into a monthly habit. Whether you choose a 36-month carrier installment at 0% APR, Apple Card Monthly Installments, or a BNPL split at checkout, the math is what matters. Compare the total cost, understand the interest terms, and bring your trade-in to the table. Do that, and your next phone upgrade can feel a lot less like a financial leap and a lot more like a sensible monthly decision.
