Sprint doesn’t want you to buy your next phone

Sprint (S) would like you to get one number out of your mind when you shop for a phone: its price.

Instead, the nation’s fourth-biggest carrier wants you to consider leasing — and not just to get the high-end phones it previously reserved for such programs. Its new Flex option covers every phone it sells.

Sprint.
Sprint wants you to lease your phone.

But while Flex will make it easier to upgrade every year, it will come with costs and limits of its own — starting with an end to installment-payment pricing at the carrier. In other words: Sorry, there will be math.

How it will work

Flex, announced Friday morning, starts with relative simplicity. Pay no money down, then pay a lease fee equivalent to the monthly installment-payment plans on other carriers.

After 12 months, you can turn in that phone and get a new one at no extra cost if it’s a new Apple (AAPL) iPhone or Samsung Galaxy. That’s much like Sprint’s current “iPhone Forever” and “Galaxy Forever” programs — but with Flex, you can reserve an annual upgrade on other phones if you opt into paying $5 more a month at sign-up.

On any Flex-leased phone, after 18 months you can choose to turn it in and get a new one or pay off the balance, either all at once or in six installments. Sprint can then refurbish the phone and unload it in the U.S. or elsewhere (its parent company SoftBank owns the phone-distribution firm Brightstar).

You will still be able to buy a phone from Sprint, but you’ll need to pay the full price upfront.

A separate Flex Deals option will cover some cheaper phones and also permit annual upgrades without the $5 monthly surcharge.

Four low-end models—the Samsung Galaxy J3, LG’s Tribute HD, the ZTE Max XL and the Alacatel Go Flip — will lease for $5 a month and require $25 upfront. Another four—used and refurbished iPhone 6s, the Galaxy J7 Perx and the LG Stylo 3 and X Power—will lease for $10 a month after $30 upfront.

Cost comparisons

Will you save money? Compare your costs to get a new iPhone every year via the two other major annual-upgrade schemes, Apple’s iPhone Upgrade Program and AT&T’s (T) Next Every Year.

At Apple, an iPhone 7 with 32GB of storage would cost $32.41 a month—including AppleCare+ device protection. After a year, you’d have spent $389. Because Apple sells iPhones unlocked under this program, you could hop from carrier to carrier in that time and use cheap prepaid SIMs when traveling internationally.

At AT&T, you’d spend $27.09 a month for a one-year total of $325. That doesn’t include a device-protection plan and would keep the phone locked. Travel overseas with it, and you’re stuck with extortionate roaming rates that start at $40 for 200 megabytes of data.
