Also for this trip

No second eSIM

Land in Seoul and the same plan keeps working. Nothing to buy, nothing to install.

Room for a detour

The same plan covers Hong Kong, Thailand, Vietnam and most of Southeast Asia if the trip grows.

Your number stays

Calls and bank codes keep reaching your usual line while the eSIM carries the data.

Three steps, then forget about it

  1. 1

    Pick a destination

    Search a country or region. The price shows in your currency, taxes in.

  2. 2

    Install in minutes

    Pay and the eSIM installs itself. No physical SIM, nothing to scan.

  3. 3

    Land online

    Your data is live the moment you switch on. Keep your usual number.

Good to know

Is there one eSIM for Japan and Korea?
Yes. Our Asia plan covers both, plus 18 more countries, on a single eSIM.
Is it better than two separate eSIMs?
For a trip across both countries, usually yes: one purchase, one installation. If you spend almost all the time in one country, a single-country plan can cost less.
Does it include Taiwan?
No, Taiwan is not in the Asia plan's list of countries.
