🌏 eSIM for Asia
Southeast Asia is built for multi-country trips — Thailand to Vietnam to Malaysia in a fortnight is normal, and buying a separate eSIM in each is both slower and dearer.

Practical notes
- Strong across the Southeast Asian mainland and the major island destinations.
- Ride-hailing is the default way to get around most Asian cities and needs a live connection.
- If you are staying in one country for the whole trip, compare against that country's own plans first.

Questions about Asia
How many countries does the Asia eSIM cover?
20 destinations on one eSIM, listed above. You install it once and it keeps working as you cross borders — no swapping, no buying again at each stop.
Is a regional plan cheaper than buying each country separately?
Usually, once you are visiting three or more. For one or two countries a local plan is normally cheaper per gigabyte — the destination pages show that directly, so compare before you buy.
When does the plan start?
When the eSIM first connects to a network inside the coverage area, not when you buy it. You can install it before you leave and it will wait.
Can I add data if I run out mid-trip?
Yes — reloadable plans can be topped up in the app without a new eSIM, which matters more on a long multi-country trip than a short one.
Do I keep my own number?
Yes. The regional eSIM adds a data line alongside your existing SIM, so calls and texts still arrive on your usual number.
Does the Asia eSIM cover my destination?
It covers the 20 destinations listed on this page. If a country is not in the list, its own page on this site will have a local plan, and the app shows the exact coverage of every plan before you pay.
Is there an unlimited Asia eSIM?
No. Plans run from 1 GB to 50 GB; the app shows live usage and reloadable plans top up without reinstalling.
