South Korea eSIM tips
- You can scan the QR before you travel. Plans start counting when you arrive in Korea, and must be activated within 60 days of purchase.
- Expect about 1.5 GB a day: 10 GB for 5 days, 20 GB for 7–10 days. If you don't want to count data, pick Unlimited.
- Best Korea GB and Unlimited allow hotspot sharing. The SKT and LG U+ local SIMs do too, but SKT 5G limits hotspot to 1 GB a day.
- LG U+ includes a T-Money card on plans of 3 days or more, collected at Incheon, Gimpo or Gimhae airport. LG U+ doesn't work on iPad, tablets, Google Pixel, Motorola or OPPO, and SKT doesn't work on iPad or tablets.
