Internet, WiFi, SIMs & Adaptors

Internet and Wi-Fi in South Korea

South Korea boasts some of the world’s fastest internet speeds and excellent connectivity. Free Wi-Fi is available in most public spaces, including airports and train stations, coffee shops and restaurants, shopping malls and public parks in major cities. 

For constant connectivity, consider renting a portable Wi-Fi device (available at airports) or purchasing a local SIM card. These options typically provide unlimited data at reasonable rates. Major international websites and social media platforms are accessible without VPNs. PC bangs (internet cafés) are abundant if you need a computer with high-speed internet.

Mobile Phones and eSIMs in South Korea

Using your mobile phone in South Korea is straightforward, with several options available: 

• International roaming: Check with your Australian provider for roaming packages, though these can be expensive 
• Local SIM cards: Available at airports, convenience stores, and telecom shops (passport required for purchase) 
• eSIMs: Electronic SIMs are increasingly popular and can be purchased online before travel through providers like KT, SK Telecom, or global eSIM services 

Most modern smartphones support eSIM technology, but verify compatibility with your device before purchasing. 

Local calls and data are quite affordable with Korean SIMs or eSIMs, with options ranging from short-term tourist packages to 30-day unlimited data plans. 

Travel Adaptors and Electronics

South Korea uses Type C and Type F electrical outlets with a standard voltage of 220V. Pack the appropriate adaptors for your devices. Most modern electronics like phones and laptops can handle the voltage difference automatically, but check your devices before travelling.
