Planning a trip to Thailand and looking for the best eSIM Thailand?
Here’s a simple guide to the most reliable Thailand eSIMs for Malaysians — so you can stay connected throughout your trip without paying expensive roaming charges.
You’ve probably come across popular Thailand tourist SIMs and eSIMs from local telcos like AIS, DTAC, or TrueMove, which often include large data bundles with 8–15 days of validity. These plans are great if you’re staying longer or travelling extensively around Thailand.
However, for most Malaysians, these plans can be more than you actually need. Many trips to Thailand last just 3–5 days, whether it’s a short Bangkok getaway, a Phuket beach holiday, or a quick business trip. In these cases, shorter-duration eSIMs are more affordable and practical — for example, BuzzyBee’s 7-Day Unlimited Thailand eSIM offers excellent value and is perfect for short stays.
That’s why many Malaysians prefer buying Thailand eSIMs from platforms like BuzzyBee or Klook, where you can pay in Ringgit, activate instantly via QR code, and choose flexible options such as 3-day, 5-day or 7-day plans. If you prefer international providers, Holafly also offers reliable Thailand eSIMs with unlimited data.
Roaming from Maxis, Celcom, Digi, or U Mobile is still a convenient option, but travel eSIMs usually provide better value, faster local network speeds, and more flexibility — especially for short trips.
In this 2025 guide, we compare the best Thailand eSIM options for Malaysians based on price, coverage, speed, and overall value, so you can easily pick the best eSIM for your next Thailand trip.

- Choose a plan that fits your trip length — pick 3, 5, 7, 10, or 15-day options depending on how long you’re staying in Thailand.
- Check Fair Usage Policy (FUP) and hotspot availability — some “unlimited” plans have daily high-speed caps or may not allow tethering.
- Install your eSIM before travelling — set it up at home on Wi-Fi and simply turn on mobile data when you arrive in Thailand.
Using an eSIM in Thailand
What is an eSIM and how does it work in Thailand?
An eSIM is a digital SIM that you install directly on your phone—no physical card needed. Activation is usually done by scanning a QR code, and your plan’s validity follows local time in Thailand. eSIMs work on most modern iPhones, Samsung Galaxy phones, Google Pixel models, and other eSIM-enabled devices.
Check if your device supports eSIM.Must-have apps for travellers in Thailand
- Maps & Transport: Google Maps, Grab, Moovit
- Payments: GrabPay, Google Pay, Apple Pay (widely accepted in major cities)
- Ride-hailing & Taxi: Grab, Bolt, Line Taxi
- Travel & Tickets: Klook, Trip.com, Agoda
- Messaging: WhatsApp, Telegram, LINE
Differences between eSIMs and traditional SIM cards
Buying a physical SIM in Thailand usually requires visiting a shop or convenience store (e.g., 7-Eleven, FamilyMart) and may involve waiting or filling in registration details. With an eSIM, you can:
- Activate instantly without visiting a store
- Arrive connected the moment you land
- Keep your Malaysian number active (dual-SIM support)
- Avoid swapping or misplacing tiny SIM cards
