Frequently Asked Questions

Everything you need to know about this eSIM plan.

Install your Korea eSIM the evening before your trip begins. Validity starts from the moment of installation - not from purchase and not from first data use. Installing at home the night before means your plan is live and ready the moment you land at Incheon, with no setup stress at the airport.
Always purchase at least one extra day beyond your planned stay. The 11:59 PM GMT+8 cutoff may arrive earlier than expected depending on your home country's time zone, and travel delays can eat into your remaining validity. The extra day ensures you're covered for your full journey.
Daily plans give you a set data allowance per day - great for flexible itineraries where your usage varies. Total plans provide a fixed data pool to use across your entire trip at your own pace. Unlimited* plans offer the most freedom for heavy users, hotspot sharers, or remote workers - though speeds may be reduced after reaching a certain usage threshold. 
If you're unsure, our support team can help you pick the right plan based on your trip length and usage habits.
Your Korea eSIM by Teclapi runs exclusively on SKT (SK Telecom) - South Korea's largest mobile network operator with approximately 22.4 million subscribers and a 39% wireless market share. SKT has won OpenSignal's Best Network award for South Korea, with 9 sole wins across metrics including coverage, consistency, and reliability. For travelers, this means the most reliable and widest-reaching network across the entire peninsula.
Yes. The Seoul Metro has full 4G and 5G coverage in all stations and tunnels - you can stream video underground. KTX bullet trains maintain strong 4G and 5G signal along all major routes including Seoul-Busan and Seoul-Gwangju. South Korea is one of the few countries in the world where underground and high-speed rail connectivity is genuinely excellent.
Expect some of the fastest mobile speeds you've ever experienced. SKT achieves average 5G download speeds of 1,064 Mbps - the highest among South Korea's three major operators. Even on 4G LTE, speeds are consistently fast across the entire country. For context, most travelers report faster data speeds in Korea than their home broadband connection.
Google Maps works on your Korea eSIM, but has significant limitations in South Korea, due to South Korean government mapping restrictions, Google Maps does not provide transit directions or accurate walking routes. We strongly recommend downloading Naver Map or KakaoMap before your trip - both are free, available in English, and are far more accurate for navigating Seoul's subway, bus routes, and walking directions throughout Korea.
No - this is a data-only eSIM for South Korea. It does not include a local Korean number for voice calls or SMS. For all communication needs, KakaoTalk, WhatsApp, FaceTime, and other VoIP apps work perfectly over your data connection.
