Travel tips for Südkorea China Japan
Install your eSIM before you board. It's much easier on home Wi-Fi than airport Wi-Fi.
Your plan only starts when you switch to it at your destination — not when you install it.
We send an 80% data warning by email and in-app. Top up before you hit 100%.
Enable "Data Roaming" in your eSIM settings after landing — this is required for the plan to activate.
Dual-SIM uses slightly more battery. Carry a power bank for full-day itineraries.
WhatsApp, iMessage, and all data-based apps work normally — they use the eSIM data automatically.
Compatible devices
Most phones from 2019 onward are eSIM-ready. We check compatibility automatically at checkout.
