Korean Transit & Tourism Routing Service (White-Label for Telecoms)

A dedicated routing and navigation backend service that telecom carriers (SK Telecom, KT, LG U+) embed into their own apps or offer as a premium VAS (value-added service) to international roaming customers. The service integrates real-time Korean transit APIs (Naver Map, Kakao Map, Korean subway/bus systems), tourist POI data, and multi-modal routing (subway + bus + walking + taxi). Carriers white-label it and charge roaming customers a small premium (₩2,000–5,000/month or ₩500 per trip) on their phone bill or as an add-on data package.

SERVICE

25 weeks • 70% confidence

Value Proposition

Telecom carriers gain a high-margin VAS that reduces churn among confused tourists and increases data/voice usage (tourists stay connected longer, use more data). Tourists get seamless, carrier-integrated navigation without downloading another app or buying a local SIM. Beats standalone apps because it's pre-integrated into the carrier's existing billing and UX.

Target Audience

International roaming customers of SK Telecom, KT, LG U+; inbound tourism operators; hotel concierge services

Key Features

  • Real-time Korean subway/bus schedules and transfers via official Korean transit APIs
  • Multi-modal routing (subway + bus + walking + taxi) with cost/time tradeoffs
  • Tourist POI database (restaurants, temples, nightlife, convenience stores) with Korean business hours and phone numbers
  • And more, with full implementation detail...

Tech Stack

Naver Map API, Kakao Map API, Korean subway/bus transit APIs Node.js or Python backend for real-time data pipeline PostgreSQL + PostGIS for geographic routing OSRM (Open Source Routing Machine) or Vroom for multi-modal optimization

Original Problem

Tourists struggle to navigate South Korea without reliable local navigation apps

International travelers visiting South Korea face significant friction using Western navigation apps (Google Maps, Apple Maps) that lack real-time Korean transit data, local business information, and accurate routing for Korean public transportation systems. Current solutions fail because they don't integrate Korean-specific services like Naver Map or Kakao Map APIs, leaving tourists dependent on unreliable workarounds or expensive local SIM cards. This creates a painful gap between arrival and functional navigation that costs tourists time, money, and frustration.
