Mobile connectivity in East Asia
East Asia has some of the fastest and most reliable mobile networks on the planet. Japan's NTT Docomo and SoftBank run dense 5G networks across all major cities and even most rural train lines. South Korea's SK Telecom and KT Corporation cover the entire peninsula with 5G and strong 4G fallback.
The challenge for South Africans is cost: Vodacom and MTN roaming in Japan and South Korea can be expensive. On a two-week trip, those roaming charges add up fast. A HelloRoam eSIM gives you a prepaid data plan for one flat price, and speeds depend on the local network.
- Japan and South Korea have the world's most advanced 5G networks
- Tourist SIM cards available in Japan and Korea at major airports
- Japan requires passport registration for physical SIM cards
- Vodacom and MTN roaming in East Asia adds up fast on a long trip
- HelloRoam eSIM activates before you leave South Africa

eSIM Travel Tips for East Asia
Get a Japan IC transit card at the airport
Japan's Suica and Pasmo IC cards work on trains, buses, and convenience store purchases. Load them with yen and tap in and out of stations. Use your data connection to plan routes in Google Maps before each journey.
Download Naver Maps for South Korea
Google Maps has limited public transport routing in Seoul. Download Naver Maps or Kakao Maps before you arrive for accurate bus and subway directions. Both apps work excellently on 4G and 5G connections.
Japan's train network is extensive but complex
The Japan Rail Pass is worth it only if you plan multiple Shinkansen (bullet train) journeys. Use Hyperdia or Google Maps with live transit to plan routes. Your HelloRoam eSIM data lets you check trains in real time.
Convenience stores are your best friends
FamilyMart, 7-Eleven, and Lawson in Japan and South Korea are open 24 hours and sell everything from hot food to phone chargers. Most have free Wi-Fi, but your data connection means you never need to find it.
Seoul to Busan on KTX is 2.5 hours
South Korea's KTX high-speed rail connects Seoul to Busan in under three hours. Buy tickets on the Korail website before you travel. Your data connection handles ticket downloads and real-time platform updates.
East Asia mobile networks: technical notes for South African travellers
Japan's NTT Docomo uses LTE Band 1 (2100 MHz) as its primary band, with Band 19 (850 MHz) for rural coverage. SoftBank uses Band 1 and Band 8 (900 MHz). Most South African phones support Band 1 but may not support Band 19, so rural Japan coverage can be weaker on an imported handset. South Korea's SK Telecom and KT use Band 1, 3 (1800 MHz), and 5 (850 MHz). Samsung Galaxy phones bought in South Africa are generally fully compatible. Japan introduced mandatory SIM registration in 2023, meaning foreign visitors cannot buy a Japanese SIM without showing their passport at a carrier shop. Tourist-specific data SIM cards sold at airports bypass this through a pre-registration system. HelloRoam eSIM avoids any airport queue by activating before departure.

Cat
On a trip to Europe, my hotel Wi-Fi was so slow and outside Wi-Fi was unreliable. I couldn’t take it anymore so I got helloroam for a few days. It was tricky to set up correctly because of the primary settings (with my original number). But I reached out to their customer service via WhatsApp. Super responsive and helpful, with specific and clear steps to troubleshoot. Appreciate having 4G roaming instead of being stuck with in and out Wi-Fi during my trip!!
Rated 5 out of 5 by this reviewer
Very good experience! The eSIM was easy to set up and worked great in London. It was much cheaper than it would have been to use my own operator there.
