From real experience
When purchasing a SIM card in South Korea, options are available both for pre-ordering online (e.g., via Wowpass) and buying directly at the airport upon arrival. According to user experiences, the choice of provider at the airport generally offers similar pricing and quality, making on-the-spot purchases a convenient option.
Incheon Airport procedures for SIM cards and currency exchange: SIM cards are readily available and easy to purchase in the airport after baggage claim, with numerous stalls. eSIM is an alternative if supported. Currency exchange rates at the airport are generally poor; it's advisable to exchange only a small amount for immediate needs and the rest in Seoul. T-money and Wowpass are also more conveniently acquired or topped up in the city.
In South Korea, connectivity options include e-SIMs and physical SIM cards. When choosing an e-SIM, prioritize data volume; higher daily limits (e.g., 100 GB/day) ensure consistent high-speed internet compared to lower limits that might throttle speeds. For devices without e-SIM support, SIM cards can be purchased at the airport or online. Public Wi-Fi is widely available, including on trains.
Major mobile operators in South Korea (KT, SK Telecom, LG U+) offer similar quality and coverage. Travelers can choose based on specific plan details and personal preference. LG U+ and KT are mentioned as reliable options.
Purchasing custom Apple hardware in South Korea is difficult for tourists as local online stores often require a local phone number and bank card. Stock of non-standard configurations (e.g., 64GB RAM) in physical stores is rare. Buying via Coupang's official store is a potential alternative if delivery timelines permit.
When purchasing Apple laptops in Seoul, consider the availability of US keyboard layouts and the tax-free option. Check estimated delivery times for custom configurations. While Korean layouts are an alternative, US layouts can be ordered, potentially offering cost savings after tax refunds.
Trip.com is generally considered a reliable platform for booking travel arrangements, including flights, trains, hotels, eSIMs, and attraction tickets. Users have reported positive experiences with customer support and successful payments using various methods, including Mir cards, for travel to Europe and China. It is a recommended option for booking travel.
For Korea internet access: physical SIM cards purchased via marketplaces (e.g., Ozon) or local airport pickup services (via Trip.com) are often more cost-effective than eSIM adapters. Physical cards are ideal for phones lacking eSIM support.
For e-SIM data plans in South Korea, 2-3 GB per day is generally sufficient for basic navigation and social media use. However, for heavy data consumers (streaming videos, extensive browsing), plans offering 100 GB per day are recommended to maintain high-speed internet throughout the trip. Be aware that lower daily data limits might experience speed reductions after exceeding the quota, even if the overall plan offers a large total capacity.
For internet access in Seoul, it is recommended to get an eSIM, as it is generally reliable and cost-effective, often available for purchase on platforms like Trip.com.
For individuals planning to study in South Korea on a D-4 or D-2 visa, it is important to note that an existing K-ETA may need to be canceled. Various agencies offer comprehensive services for visa applications, including university selection, document preparation, submission to universities and embassies, and assistance with obtaining resident cards, SIM cards, and bank accounts. Accurate information matching your study objectives is crucial for a successful application.
For telecommunication needs in South Korea, purchasing a local SIM card or eSIM is highly recommended over using Russian roaming services due to cost-effectiveness. Options are available on platforms like Trip.com. If your phone supports eSIM, consider an 'Asia' plan which covers transit stays (e.g., in China) and the duration in South Korea. Alternatively, obtaining a separate Chinese SIM for transit and then a Korean SIM is feasible. Local SIM cards typically cost around 35,000 KRW per month and offer stable connectivity without the need for VPNs.
If you need to purchase a non-iPhone mobile phone in Busan, South Korea, head to official Samsung stores or other major electronics retailers. It's advisable to inquire about the phone's version (global or Asian) as local models may be region-locked. Global versions can typically switch to Russian language settings in the phone's menu. Prices might be more competitive than in Russia, especially with tax-free services. Simpler, older models are also available.
For obtaining a South Korean SIM card:
1. eSIMs are a convenient option, costing approximately 7-9 Euros for a week's service.
2. Providers like 'Chingu Mobile' also offer reliable local SIM cards.
3. Purchasing either an eSIM or a physical SIM card upon arrival or in advance is recommended to ensure connectivity.
Opening a bank account in South Korea requires a local Alien Registration Card (ARC/ID). A local phone number is often a prerequisite for a bank account, and some carriers require a bank account for SIM contracts. Non-residents may struggle to open accounts. Long-term absence may lead to service suspension; users should inquire about suspension/dormant status options for both SIM and bank accounts.
The KakaoTalk 'Relax Mode' is a security restriction. It limits messaging capabilities for accounts not verified with a Korean phone number. It can often only be unlocked or bypassed if a user with a verified Korean number sends a message to the restricted account first.
Inquire about the availability of Russian audio guides at the National Museum of Korea. If not available, check for Russian language support in the museum's official app or alternative resources.
Organic Maps is recommended as an offline navigation application for use in Seoul. Users can download city maps in advance for navigation without an internet connection.
Essential mobile applications for traveling in South Korea include: Naver Map (recommended over Google Maps for navigation), Wowpass (for a local payment card), Subway (for public transport), and Kakao Taxi/K.Ride (for ride-hailing services). It is also advisable to set up KakaoTalk before arrival, as registration codes may experience delays.
Phones purchased outright (without carrier installment plans) in South Korea are generally compatible with SIM cards in other countries, including Kazakhstan. However, devices acquired through carrier financing may be subject to SIM-lock restrictions. It is advisable to verify this aspect with the vendor before purchase if international use is intended.
SIM cards in South Korea can be purchased at convenience stores like 7-Eleven or CU. While specific designs vary, convenience stores are a common point of sale.
In South Korea, public Wi-Fi is widely available in hotels, shops, public transport, and most buildings, but generally not on the streets. e-SIMs (e.g., from Trip.com for Asia coverage) are a popular and effective solution for mobile data. Users report high data allowances (e.g., 100GB/day) at competitive prices (around 1800 RUB for 14 days) and good network speeds, even for video calls, often surpassing hotel Wi-Fi. e-SIMs typically do not come with a phone number; communication is primarily via internet-based messengers (e.g., Telegram works without VPN). A physical Russian SIM card will be inactive while the e-SIM is in use, requiring manual switching for calls or SMS (e.g., for hotel check-in verification).
For issues with international roaming on a Russian phone number, it is advisable to contact the support line. Contact information is usually available on the service provider's cards.
When choosing a Korean SIM card for travel, consider 'kadaphones' (prepaid SIMs) from providers like LG U+ or KT, often available with a free first month. Ensure the SIM has a physical number (starting with 010) for SMS functionality. Tourist-specific SIMs might have limitations.
Tourists should check if their device supports eSim before purchase. eSims for Korea are electronic files downloaded via email instructions. While some users suggest installing in advance, activation usually occurs upon arrival in Korea. Ensure roaming/data settings are managed according to the specific provider's instructions.
When purchasing iPhones in South Korea, inquire about the SIM card version. Some versions might be eSIM-only, similar to mainland China, which could impact usability in other countries for physical SIM card users.
Registration for KakaoTalk, which previously often required a Korean phone number and passport, has reportedly become easier for users located outside of Korea, including in Russia. Users may now be able to register without a Korean SIM card, potentially due to reduced server load or system updates.
Kakao Map can be used offline after downloading relevant map data. For full functionality, including integration with KakaoTalk, purchasing an e-SIM is recommended.
Some services in South Korea may only work with a VPN. A user from Krasnodar Krai reported issues accessing a service without a VPN, experiencing disconnections.
