Asia travel data eSIM
What is an Asia eSIM?
An Asia eSIM is designed for travelers who plan to move between multiple destinations such as Hong Kong, Thailand, Japan, Singapore, and Malaysia without swapping physical SIMs. It lets you stay connected for maps, bookings, and communication while hopping between bustling cities and remote sites, all from a single digital profile that works wherever you roam within the listed countries.
You receive one QR code that installs the eSIM on your unlocked phone. After the first connection to a local operator network in any included country, the plan’s validity begins and continues across borders, with the network operator potentially changing as you move from one country to another.
Coverage
Countries included in the Asia eSIM
The eSIM links to a local operator network in each of the included countries—Macao, Hong Kong, Taiwan, Thailand, Singapore, Japan, South Korea, Vietnam, Indonesia, China, Malaysia, and Cambodia. Data access depends on the specific operator’s network in the area where you are located, allowing you to use mobile data wherever the operator is present.
5 plans are available, from $6.90 up to $79.90. Every plan is data only and delivered by QR code.

Questions people actually ask
If yours is not here, write to us — we answer within 24 hours.
Which countries does the Asia eSIM include?
It includes 12 destinations, among them Macao, Hong Kong, Taiwan, Thailand, Singapore, Japan, South Korea, Vietnam, Indonesia, China, Malaysia, Cambodia. The complete list with flags is shown on this page. The plan is not valid in countries outside that list.
Can this plan be used in a country that is NOT in the list?
No. The plan works only in the listed countries: Macao, Hong Kong, Taiwan, Thailand, Singapore, Japan, South Korea, Vietnam, Indonesia, China, Malaysia, and Cambodia.
Which plan size suits a trip through two or three listed countries?
As a rough guide, a 3 GB or 5 GB plan often covers short stays in two or three countries, while a 10 GB or 20 GB plan provides more flexibility for longer or heavier usage across the same number of destinations.
Will I lose my own phone number?
No. Your physical SIM stays in the phone and keeps your number for calls and WhatsApp. The eSIM only carries data, so both work side by side.
When does my plan start counting down?
When the eSIM first connects to a network at your destination — not when you buy it. So you can install it days before you fly without losing any time.
Is my phone compatible?
Most phones from 2018 onwards are: iPhone XS and later, Google Pixel 3 and later, Samsung Galaxy S20 and later. Your phone also has to be carrier-unlocked. Dial *#06# — if an EID appears, you have eSIM. Full list on our Device Compatibility page.
How fast will I get my QR code?
Usually within a couple of minutes of payment, by email. If it has not arrived, check spam first, then write to us and we will resend it immediately.
Can I use hotspot or tethering?
Yes, on every plan we sell. Share the connection with a laptop, a tablet or the rest of your group.
What if I change my mind?
If you have not installed the eSIM, you get a full refund within 180 days. Once a profile is activated and data has been used it cannot be refunded — the allowance is consumed from the network. Full detail in our Refund Policy.
Do you sell plans for groups?
Yes. For Umrah and Hajj groups, student trips and tour operators we deliver the QR codes as a single batch before departure, at group rates. Email us with your group size and destination.
