eSIM Asia
The Asia eSIM runs on local 4G and 5G networks in 20 countries, from 1GB to 20GB, prepaid with no contract and no registration — online the minute you land at Bangkok Suvarnabhumi.
Your Selection
Your plan only starts counting when the eSIM first connects at your destination — so you can buy today and travel in three weeks.
How does Simbye eSIM work for Asia?
Get connected in under 2 minutes
Choose your plan and buy it
Pick the data amount and the validity, pay online, and the email with the link and QR code arrives a few minutes later.
Set it up before you fly
Install the eSIM at home over Wi-Fi, it takes a few minutes. After landing – at Bangkok Suvarnabhumi, Singapore Changi, Tokyo Haneda, Seoul Incheon, Kuala Lumpur or Sydney – your phone finds the network on its own.
Turn on data roaming
Select the new line for mobile data and switch data roaming on for it. Leave data off on your usual line so it stays quiet. There is no APN to type in anywhere.
Check Device Compatibility
Make sure your device supports eSIM before purchasing

eSIM or a local SIM card in Asia?
| Compared | Simbye eSIM | Local SIM card |
|---|---|---|
| Crossing a border | Nothing to swap, the plan keeps running in all 20 countries | Buy a new card in every country |
| Setup | At home before you fly, with the QR code from your email | At the airport or in a shop, often with a queue |
| ID and registration | Not needed, you travel on a foreign plan | Required in several countries, among them India, China and Saudi Arabia |
| When you get online | As soon as your phone finds a network after landing | Only once you have bought the card |
| Your own number | Stays active in your phone as a second line | Takes the card slot – with only one slot, your card has to come out |
| Local phone number | None, this is a data-only plan | Local number included, handy for delivery drivers and callbacks |
| Hotspot | Allowed, laptop and tablet can share it | Allowed on some plans, the terms are usually only in the local language |
| Data and validity | 1GB to 20GB, 7 to 90 days, fixed before you travel | A new package in every country, top-ups often cash or local card only |
One eSIM for the whole trip instead of one per country
An Asia trip rarely stays in one country. Bangkok, then Siem Reap, then Ho Chi Minh City, home via Singapore. Or Tokyo, Seoul, Hong Kong. With country eSIMs that means four purchases, four setups and four leftover data blocks that expire unused – plus the question, at every border, of whether there is Wi-Fi right now.
With a regional plan you buy once and draw from one pot. How much you need depends on what you do: maps, chats and bookings use little, video and video calls use a lot. For a short city break 1GB over 7 days or 3GB over 15 days is enough, for two to four weeks on the road 5GB or 10GB over 30 days is the right size, and for the long loop there is 20GB over 90 days.
Then there is the part you only notice on the road: after a night flight you are not standing in arrivals in front of a shop that opens at seven, you are booking your taxi while still waiting at the baggage belt.
Where the plan stops
The real limit is the country list, not the network. It stops at places that often belong to a round trip: Laos between Thailand and Vietnam, Taiwan as a side trip from Japan, Nepal after India, the Maldives after Sri Lanka. There you are offline until you reach a listed country again.
The same goes for changing planes: Dubai, Abu Dhabi, Doha and Istanbul are not on the list, and that is exactly where many Asia travellers have their layover. Until the connecting flight, airport Wi-Fi is your only fallback.
And it stays a data plan: no phone number, no calls, no SMS over the network. For every app that sends you a code at sign-up you still need your own number – best to get those sign-ups done before you leave. Download maps, tickets and translations offline as well, and a dead spot stays an annoyance instead of a problem.
What this plan does not cover
The list holds 20 countries – and a few well-known destinations in the region are missing from it. Not included are Taiwan, Laos, Myanmar, Nepal, Bangladesh, Bhutan, the Maldives, Brunei and Mongolia. From the Middle East only Saudi Arabia, Kuwait and Israel are on the list: the plan does not apply to a stopover in Dubai, Abu Dhabi, Doha or Istanbul, and that is exactly where many Asia travellers change planes.
Mainland China is included. In China, Google, WhatsApp, Instagram and similar services are blocked. Whether this eSIM gets you past that depends on how your traffic is routed – we do not promise it, so better not to plan around it. Set up a VPN before you fly, since inside the country you will barely be able to install one. This does not apply in Hong Kong or Macao, which run their own networks.
