Singapore, Malaysia & Thailand travel data eSIM
What is a Singapore, Malaysia & Thailand eSIM?
If your itinerary includes Singapore, Malaysia and Thailand, a single eSIM lets you stay connected without swapping cards. Whether you’re exploring the skyscrapers of Singapore, the beaches of Phuket, or the markets of Kuala Lumpur, the eSIM provides data‑only service for the whole Southeast Asian triangle, simplifying travel logistics and keeping your home number active.
One plan and one QR code are enough for the entire trip. After scanning the QR code, the eSIM activates the first time it contacts a local operator network in any of the three countries. The underlying operator may change as you cross borders, but the same plan remains valid for the duration you selected.

Questions people actually ask
If yours is not here, write to us — we answer within 24 hours.
Which countries does the Singapore, Malaysia & Thailand eSIM include?
It includes 3 destinations, among them Thailand, Singapore, Malaysia. 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 Singapore, Malaysia and Thailand as listed on the page.
Which plan size suits a trip through two or three of the included countries?
As a rough guide, a 3 GB or 5 GB plan is often enough for a short visit to two countries, while 10 GB or 20 GB provides more flexibility for a longer itinerary covering all three.
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.
