Phone Discounts Now Hide in the Plan, Not the Price

The Day the Cap Came Off, No One Lined Up at the Store

On July 22, 2025, Korea’s Mobile Device Distribution Structure Improvement Act—known as Dantongbeop, the “handset distribution law”—was repealed after roughly 10 years in force. From that day, carriers were no longer required to publicly disclose device subsidies, and the cap that had limited retailers’ extra subsidies to 15% of the disclosed amount disappeared along with it.¹ Customers who chose the 25% plan-fee discount (seontaek yakjeong, a contract-based rate cut in lieu of a device subsidy) became eligible to receive a retailer’s extra subsidy as well, and carriers were now permitted to offer different subsidy amounts depending on subscription type or plan.² The seontaek yakjeong system itself, along with the ban on discriminating by age, region, or physical condition, was carried over unchanged into the Telecommunications Business Act (Jeongi Tongsin Saeopbeop).³

The expectation was simple: lift the cap, and carriers and retailers would compete on subsidies, which would make phones cheaper. 1 year later, the result has been quiet. The feared “seongji chaos”—the frenzy around underground stores secretly offering illegal subsidies—and the sharp discrimination between users never really returned, but observers say consumers haven’t noticed much change either.⁴

Anyone thinking about switching phones really has just one question: is buying now cheaper than before? To answer it, we first need to look at what actually moved this market over the past 1 year.

People Switched Carriers When the Cancellation Fee Disappeared

Number portability is the clearest signal of how fiercely carriers compete to poach each other’s subscribers. According to the Korea Telecommunications Operators Association (KTOA), the monthly average for number portability from January to June 2026 was 657,517 cases — up just 1.5% from the same period in 2025 (647,865), before the cancellation fee was abolished.⁴

Even that 1.5% is hard to credit to the subsidy competition itself. Number portability spiked to 999,344 cases in January 2026, but that was driven by cancellation-fee waivers issued after KT’s personal data breach.⁴ Strip out January, and the February–June monthly average comes to roughly 589,000 — actually lower than the same-period average the year before. That said, the prior-year figure was itself inflated by the fallout from SK Telecom’s SIM hacking incident, so this comparison alone can’t settle how much the fee’s removal actually mattered. Looking only at portability among the three major carriers, the numbers climbed to 312,804 in April 2025, when the hacking scandal broke, and to 520,046 in July 2025, when SK Telecom rolled out its cancellation-fee waiver.⁵

Marketing spending at all three carriers rose as well. In Q1 2026, SK Telecom spent 7.1% more than the same period a year earlier, KT 9.9% more, and LG Uplus 11.7% more. But here too, the increases are tangled up with subscriber-retention spending after the hacking incidents and new product launches, making it hard to attribute the rise to the fee’s removal alone.⁴

Put the past year’s numbers together, and the moment people actually moved en masse wasn’t when the subsidy cap came off — it was when the cancellation fee for leaving got waived.

Device spending fell, but monthly bills didn’t

How did spending change on the consumer side? There’s an analysis from Representative Hwang Jeong-a’s office on the National Assembly’s Science, ICT, Broadcasting and Communications Committee, based on microdata from the National Data Agency’s household trend survey.⁶ Looking at total telecom spending—device purchase costs plus service fees combined—the bottom income quintile’s monthly average came to ₩53,736 (~$38.4) in Q2 2026, down 8.0% from ₩58,385 (~$41.7) in Q2 2025, just before the policy was abolished.

Of that, service fees actually rose slightly, from ₩47,709 (~$34.1) to ₩47,742 (~$34.1). Subtracting the two figures to isolate device purchase costs alone, that amount dropped from ₩10,676 (~$7.6) to ₩5,994 (~$4.3)—a fall of roughly 44%. Service fees rose across all five income quintiles, and only the fourth quintile (4.4%) outpaced the inflation rate (3.0%).⁶

You shouldn’t read that 44% as “phones got 44% cheaper.” These are monthly household averages, so they blend together households that bought a phone that quarter and those that didn’t. It’s possible more households simply delayed upgrading their phones as the economy worsened, or that the growing prevalence of budget smartphones played a role.⁶ Another interpretation circulating is that competition among retail subsidies drove bigger discounts on mid-to-low-end devices, which partly explains the trend. What we can say for certain is this: low-income households spent less on devices, but their monthly bills didn’t go down.

Subsidies Are Now Tied to Your Plan

One thing the repeal allowed was differentiating subsidies by phone plan. The result, according to both retail channels and researchers, is that subsidies and sales incentives have flowed toward pricier plans. The Korea Mobile Distributors Association (KMDA), in its statement marking one year since the repeal, argued that carrier incentives are concentrated on high-priced plans, constraining consumers’ choice of plan.⁷ Kwangseob Ahn, an adjunct professor at Chung-Ang University, wrote in his report that subsidies are concentrated on buyers of new flagship devices and high-priced plans, leaving subscribers to mid- and low-tier plans out in the cold.⁸

The same report also explains why number portability hasn’t surged. The market is already saturated, and people are locked into bundled perks like high-speed internet, IPTV, OTT, and membership programs, making it hard for subsidies alone to drive carrier switching.⁸ For a household that would have to move its internet and TV service too, a few hundred thousand won in device subsidy may not be reason enough to switch.

The route of escaping to a cheaper plan has also narrowed. Before the repeal, from January to June 2025, budget carriers (MVNOs) saw a net monthly inflow of 35,358 subscribers from the three major carriers. From August 2025 to June 2026, that averaged just 761 a month. The interpretation: as carriers gained more freedom over subsidies, MVNOs’ relative competitiveness weakened.⁴

To sum up, the discount hasn’t disappeared. It has simply moved from the price tag on the device to the conditions of the plan. To get a substantial subsidy, you now have to stay on an expensive plan for a fixed period — and the extra amount you pay in fees during that period is, in effect, the price of the discount.

If You’re Buying Now, Compare the Full 24-Month Cost

So you can’t answer “is buying now cheaper” just by looking at the device’s installment principal. Let’s calculate the total paid over 24 months for the same phone bought two different ways. The numbers below are hypothetical, for illustration only — not actual sales terms.

A. Taking the subsidy: You get ₩600,000 (~$432) combining the public subsidy and the additional carrier subsidy, use a ₩110,000/month plan for 6 months, then switch to a ₩55,000/month plan. Since you took the subsidy, there’s no SIM-only discount (seontaek-yakjeong, Korea’s contract discount for not taking a device subsidy). Plan charges come to ₩660,000 for the first 6 months and ₩990,000 for the remaining 18 months, totaling ₩1,650,000. Subtract the ₩600,000 subsidy from the device price, and your 24-month total is the device’s list price plus ₩1,050,000.

B. Choosing the SIM-only discount: With no subsidy, you get 25% off the ₩55,000/month plan, paying ₩41,250 per month. Over 24 months that’s ₩990,000 in plan charges, so your total is the list price plus ₩990,000.

In this scenario, B — who took zero subsidy — comes out ₩60,000 cheaper. But if A’s subsidy were ₩700,000 instead, A would become ₩40,000 cheaper. One number flips the conclusion. And after the abolition, people who choose the SIM-only discount like B can also receive the retailer’s additional subsidy, so depending on the store, B could end up even more favorable.²

So when comparing, you need to check a few things in the contract: how many months you must keep the expensive plan, how much of the subsidy you’d have to repay if you downgrade before then, whether there are bundled add-on service requirements, and whether you can get the additional subsidy while also taking the SIM-only discount. Guidance also notes that switching plans can trigger a subsidy penalty, so you should confirm the required holding period before activating your line.³ If you buy the device unlocked (jageupje, Korea’s SIM-free retail channel) and use a budget MVNO plan instead, you can work out the 24-month total the same way and set it side by side.

Oswarld's Lens

The clearest signal from the past year, I think, came not from the subsidy figures but from the penalty fees. When the subsidy cap was lifted, people barely moved. When the cost of leaving was waived after the hacking incident, they moved in droves. A penalty waiver following a hack isn’t a common situation, so I can’t turn this into a general rule — but it does show, at minimum, where the real power to keep consumers locked in actually lies.

Lifting a price cap and generating price competition are two different things. In a market where nearly everyone already has a subscription, what carriers most want to protect is the monthly bill each subscriber pays. Once the cap disappeared, carriers used their newfound discretion not to cut device prices but to migrate people onto pricier plans. And bundled discounts keep raising the cost of switching. It’s true that the cap was one of the things blocking competition — but removing the cap alone wasn’t enough to bring competition back to life.

So if we’re going to discuss follow-up policy, I think the priority shouldn’t be whether to loosen or tighten subsidies further, but rather enabling consumers to compare terms and lowering the cost of leaving. The Broadcasting, Media, and Communications Commission’s comprehensive measures on market monitoring and preventing discrimination against users have been shelved pending further review and pushed to the second half of the year.⁴ It’s worth watching whether those measures end up addressing the transparency of terms rather than just the size of subsidies.

Closing

Repealing the Dantonbeop (Mobile Device Distribution Improvement Act) didn’t eliminate phone discounts, nor did it dramatically expand them. It moved where the discount shows up — from the device price tag to the plan’s terms. If in the store you ask “what’s the total for 24 months” before asking “how much is the phone,” you’ll have less chance of losing out in this changed market.
