Planning a trip to Singapore and looking for the best eSIM Singapore?
Here’s a simple guide to the most reliable Singapore eSIMs for Malaysians — so you can stay connected your entire trip without paying expensive roaming fees.
You’ve probably seen the popular S$12 Tourist eSIM from Singtel or StarHub, which includes 100GB and 14-day validity. It’s excellent for travellers staying one to two weeks in Singapore.
But for most Malaysians, this plan is overkill. We usually visit Singapore for short 2–4 day trips, and you don’t need 100GB of data for that. Short-duration eSIMs are cheaper and more practical — for example, BuzzyBee’s 3-Day Unlimited Plan costs only RM16.40, making it ideal for weekend getaways, concerts, or business meetings.
That’s why many Malaysians prefer buying Singapore eSIMs from BuzzyBee or Klook, where you can pay in Ringgit, enjoy instant QR activation, and choose 1-day, 3-day, or 5-day plans. If you prefer global brands, Holafly also offers reliable options with unlimited data.
Roaming from Maxis, Celcom, Digi, or U Mobile is still convenient, but travel eSIMs usually deliver better value, higher speed, and more flexibility — especially for short stays.
In this 2025 guide, we compare the best Singapore eSIM options for Malaysians, looking at price, coverage, speed, and overall value, so you can choose the most suitable plan for your next trip.

Using an eSIM in Singapore
What is an eSIM and how does it work in Singapore?
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 Singapore. 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 Singapore

Differences between eSIMs and traditional SIM cards
Buying a physical SIM in Singapore usually requires visiting a shop or convenience store (e.g., 7-Eleven) and may involve waiting or filling in 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
