Frequently asked questions

Gohub eSIM is one of the best eSIM options for South Korea, with reliable 4G coverage via SK Telecom and LG U+ across Seoul, Busan, Jeju Island, Gyeongju, and major tourist corridors. Plans include daily, fixed GB, and Call & SMS options, all prepaid and activated via QR code. Rated 4.8/5 by over 500,000 travelers worldwide.

Yes. Gohub eSIM works throughout South Korea by connecting to SK Telecom or LG U+ depending on your chosen plan. Purchase a plan at gohub.com, scan the QR code before departure, and your eSIM connects automatically when your device detects a local South Korean network. Coverage is strong in Seoul, Busan, Incheon, Gyeongju, and Jeju Island, including subway stations and KTX rail lines.

Install the eSIM via Wi-Fi before your trip. On iPhone, go to Settings > Cellular > Add eSIM. On Android, go to Settings > Connections > SIM Manager (Samsung) or Settings > Network & Internet > SIMs (Pixel and others). Your eSIM activates automatically when your device first connects to the local network after arrival. Note that each plan day resets at 11:59 PM GMT+8, regardless of your install time.

Yes. Gohub eSIM costs far less than standard carrier roaming, which runs $5–$15 per day with most US providers. Gohub South Korea plans deliver 4G data via SK Telecom or LG U+, with speed reducing to 256 kbps after your daily or total cap is reached, rather than being charged per MB at roaming rates.

A 5–7 day trip covering Seoul, Busan, and Gyeongju typically needs 10–15 GB for Naver Maps navigation, KakaoTalk messaging, and social media. Daily plans from 300 MB/day suit light users on short trips, while larger fixed GB plans cover heavier usage. Note that TikTok and ChatGPT access may be restricted by local carrier policies in South Korea.

Yes. A Wi-Fi connection is required to download the eSIM profile. Complete this at home before departure. Once installed, your Gohub South Korea eSIM connects to the SK Telecom or LG U+ network without Wi-Fi, exactly like any standard mobile data plan.

Yes. Gohub eSIM runs alongside your physical home SIM using your phone's dual-SIM capability. Keep your home SIM active for calls and texts from home while the Gohub eSIM handles South Korean data. Turn Data Roaming OFF on your home SIM and ON for the Gohub South Korea eSIM to avoid unexpected charges.

Gohub eSIM for South Korea works with all eSIM-capable, carrier-unlocked smartphones — including iPhone XS/XR and later, Samsung Galaxy S20 and later, and Google Pixel 3 and later. Your phone must be network-unlocked; carrier-locked devices will not accept a third-party eSIM. Check Settings > Cellular > Add eSIM on iPhone, or SIM Manager on Android, to confirm support.

Yes. Gohub eSIM via SK Telecom or LG U+ maintains strong 4G connectivity throughout Seoul Metro's underground network, on KTX high-speed trains between Seoul, Daejeon, Daegu, and Busan, and on inter-city express buses. South Korea has excellent indoor and underground mobile coverage, so signal interruptions on public transport are rare even in deep underground stations across the country.

Some plans do. The Call & SMS plan via SK Telecom includes 20 minutes of voice calls for receiving calls and making outgoing calls to local, Mainland China, and Hong Kong numbers, plus 10 SMS messages within South Korea. Data-only and daily plans do not include a phone number but fully support WhatsApp, KakaoTalk, and other VoIP apps over your data connection.
