South Korea's Big Three Telcos Complete Filings for Network-Agnostic Integrated Mobile Plans; SK Telecom Slated for July Launch: Kim Sungmoon Reporter / Updated : 2026-05-21 16:59:36

SEOUL — South Korea's three major mobile network operators have officially finalized the necessary regulatory reporting procedures to introduce unified telecom service packages. This strategic shift will effectively dismantle the long-standing pricing barrier between fifth-generation (5G) and Long-Term Evolution (LTE) networks. Starting next month with LG Uplus, followed in sequence by SK Telecom and KT, the nation's dominant carriers are poised to roll out integrated service plans structured strictly around data volume and transmission speeds rather than network generation. Inside sources report that all three companies have aggressively initiated the overhaul and development of their respective backend IT and billing systems to facilitate a seamless transition.

According to telecommunication industry sources on May 21, SK Telecom, the country’s largest carrier by subscriber volume, recently completed its legal reporting and review process under the government's rate-filing system with the Ministry of Science and ICT (MSIT). Consequently, SK Telecom has locked in July 2, 2026, as the official launch date for its next-generation integrated pricing structure, which will replace its legacy network-specific tiers. This milestone positions SK Telecom as the second carrier to deploy the unified system, following closely on the heels of LG Uplus, which is scheduled to commercially launch its own integrated plans on June 1.

As part of its preparatory measures for this structural transition, SK Telecom will officially close new sign-ups for 67 types of existing 5G and LTE service plans effective July 2. While current subscribers will be permitted to retain their existing network-specific plans until they proactively choose to modify or terminate their contracts, all newly arriving subscribers, device upgrades, and mobile number portability (MNP) switchers will be required to select from the newly established integrated tier system.

An industry executive familiar with the negotiations commented on the regulatory progress, stating, "All three major carriers, including SK Telecom—which is subject to the stringent pre-reporting review framework—have successfully finalized their filings for the integrated mobile subscription plans." The Ministry of Science and ICT is reportedly working hand-in-hand with the operators to optimize operational readiness and accelerate the commercial launch dates across the board to maximize public benefit.

From the consumer perspective, the consolidation of the previously bifurcated 5G and LTE frameworks into a single unified architecture will substantially simplify the plan-selection process. Furthermore, the upcoming framework guarantees that low-cost plans—even those priced in the accessible 20,000-won ($15 USD) range—will inherently feature Quality of Service (QoS) data protection options running at standard 400Kbps speeds once baseline allocations are exhausted. The central government and the telecom trio have also resolved to significantly expand the scope and baseline speeds of these QoS assurances, driving a fundamental upgrade in universal digital connectivity and communication rights for all citizens.

The integrated ecosystem is also set to deliver considerably enhanced benefits for vulnerable demographics, specifically senior citizens and youth subscribers. LG Uplus previously disclosed its promotional strategy to offer completely unrestricted voice calls and text messaging as a standard inclusion for all customers aged 65 and older. Competitors SK Telecom and KT are widely anticipated to unveil comparable or identical specialized welfare benefits within their respective July rollouts.

With LG Uplus and SK Telecom locking in firm launch dates for June 1 and July 2, market attention is rapidly shifting toward KT Corporation's impending timeline. KT's internal portfolio restructuring experienced marginal delays due to ongoing administrative overhead regarding a data compensation program, which involves provisioning 100GB of complimentary monthly data to affected users through July as redress for a prior network incident.

Reassuring the market, an official spokesperson for KT stated, "We are currently in active, close consultations with the regulatory ministry to finalize our integrated subscription framework, and we are mobilizing all internal resources to ensure that the new consumer-centric plans are brought to market as rapidly as possible."
