It's incredibly convenient, eSIM is awesome! BTS is awesome!

Guest User2026-03-28

Purchasing an eSIM from Trip.com was the best decision for my Korea trip. I received the QR code via email immediately after buying. I scanned it while still at my departure gate, and the moment I landed in Korea, I just toggled 'Data Roaming' on and was instantly connected. No lines at the airport and no physical SIM cards to lose. Highly recommend for a stress-free arrival

If you are Korean, don't buy this. This is only for non Korean passport user. This works so good. Just follow the instructions to verify you.

Guest User2026-03-15

It's very fast, powerful, and stable. Easy and hassle-free installation. Say goodbye to constantly removing and inserting your travel SIM card. The price is also reasonable.
