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?
Across Asia the eSIM wins on borders: one plan keeps running in all 20 countries and needs no registration, while local cards mean a new purchase at each frontier and passport checks in places like India or China.
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.
