Check eSIM compatibility and network-unlocked status. Enter the correct email at checkout.
- Install with a stable connection
Follow the emailed instructions. Do not delete the eSIM when troubleshooting; contact us first.
- Turn Data Roaming ON at your destination
Use the travel SIM for data and keep data roaming OFF on your home SIM. Check the APN and contact us if you cannot connect.

Before you choose a plan
What is the difference between a Daily plan and Total GB?
A Daily plan renews its daily high-speed allowance at the reset time stated for that product. Total GB is one high-speed data allowance shared across the whole validity period. Treat a Total plan as no longer usable once its high-speed allowance is exhausted. Do not rely on a 128kbps connection for normal internet use.
Does every eSIM start its validity when I reach the destination?
No. Activation rules vary by product. For the Malaysia CelcomDigi eSIM, choose your arrival date at checkout: we email the QR code about 48 hours before you land, and your plan days start on your arrival date. Roaming plans require data roaming to be switched on at the destination.
How are physical SIM cards delivered?
Physical SIM cards include free nationwide shipping within Malaysia and Thailand. Order early: public holidays, weather and courier delays can affect arrival. Choose a delivery address in one of these two countries and allow time before departure.
Is a local SIM the same as a roaming SIM?
No. Network access, setup and coverage depend on the specific plan. Follow the APN and activation instructions supplied with your order. Turn on data roaming for roaming plans, and check the listed countries and any excluded areas before buying.
Where it works
South Korea
Make your data work for your trip
Daily GB · Data per day
Illustrative example
Example: Daily 1GB for 5 days gives you 1GB of high-speed data each day. Tomorrow brings a new 1GB allowance. You cannot use all 5GB on day one. Reset time and speed after the daily allowance depend on your plan.
Total GB · Data for the whole trip
Illustrative example
Example: Total 5GB for 5 days gives you 5GB for all 5 days combined, not 5GB each day. Use 2GB today and 3GB remains for the rest of the plan. It does not reset tomorrow. Treat the plan as offline once the high-speed data is used.
Unlimited does not mean unlimited full speed. Check the speed cap and hotspot conditions for the selected plan.
Delivery & setup
Your eSIM QR code is sent to the email entered at checkout. Check device compatibility before ordering; install with a stable internet connection and do not delete it when troubleshooting.
eSIM: install within 180 days after the QR code is sent. Once installed, it must connect to the network at your destination within 30 days or it expires — your plan days start from that first connection (we suggest installing 1–2 days before you fly).
Follow the selected plan's setup instructions above. Roaming services require Data Roaming ON; local-plan exceptions are shown with your selection.
Actual signal and speed vary by location, device and network conditions.

🌐 South Korea Travel eSIM
Fast, stable data for your trip across South Korea.
🌐 Connects to South Korea's top local networks — SK Telecom, LG — auto-selecting the strongest signal wherever you are.
📊 Plan Types
🚀 Daily — a fresh batch of high-speed data every day. It renews daily whether or not you used up the previous day's data, so you're never left without data mid-trip. (Exact renewal time varies by plan.)
📦 Total GB — one fixed data pool you can use anytime, no daily limit. Once it runs out the connection stops until you top up, so choose the size that fits your needs.
♾️ Unlimited — never run out; speed managed under fair use. For heavy users & long stays.
💡 How much data? 1GB/day = maps, chat, social, email (light). 2–3GB/day = video calls, photos, some streaming (medium). 5GB/day or Unlimited = heavy streaming, video, work.
🔋 Check your remaining data anytime at the Happy Travel SIM website — Total GB plans can be topped up there too.
📩 How to get it: your eSIM QR code is emailed automatically to the address you enter at checkout — no need to leave a message. Not in your inbox? Check your spam folder.
⚠️ Please note
• Unlimited plans do NOT support hotspot / tethering (fair-use policy).
• eSIM: install within 30 days after the QR code is sent. Once installed, it must connect to the network at your destination within 30 days or it expires — your plan days start from that first connection (we suggest installing 1–2 days before you fly).
• eSIM: installs on ONE device, ONE time; the QR can't be reused once installed or deleted.
• Not sure your phone supports eSIM? Dial *#06# — if an EID number appears (not the IMEI), your phone supports eSIM.

Value for Money:works really well!
While I was in Korea, I used the SKT sim card picked up at the airport for 5 days. but as I was staying for 6 days, and SKT doesn't have a 6 days plan, I decided to purchase a last minute e-sim from here for my last day! and honestly, I regret not purchasing from them since day 1 because the Internet speed works well and it was so easy to activate too. The seller responded fast and understood my request even though I purchased it last minute and the price was so much cheaper than other places! I think that the next time I go to Korea I will try and use this e-sim instead of a physical sim card because it was so much worth it! Thank you 🤍
