What is an eSIM and why use one in Singapore?
An eSIM, short for embedded SIM, is a small chip already built into your phone or tablet that can store multiple mobile profiles digitally. Instead of inserting a physical SIM card, you simply download a data plan from an eSIM provider through a QR code or mobile app. The entire setup takes just a few minutes.
Once installed, your device automatically connects to local networks such as StarHub, SIMBA, Singtel, or M1. You can manage your plan directly in the app, monitor usage in real time, and even switch between different eSIMs without removing or replacing anything.
In Singapore, where travellers often cross between neighbouring countries, eSIMs make it easy to add or replace plans on the go, perfect for regional travel across Malaysia, Indonesia, or Thailand without changing SIM cards.
What’s better for Singapore: an eSIM or a local SIM card?
An eSIM is usually the better choice for travellers in Singapore. You can install it before your flight, activate it instantly on arrival, and skip the queues at airport SIM counters.
Local SIM cards from Singtel, StarHub, M1, or SIMBA work well too, but they require ID registration and are often limited to short-term tourist packages.
✅ eSIMs:
- Instant activation via app or QR code
- No paperwork or shop visits
- Perfect for regional trips across Asia
✅ Local SIMs:
- Include local numbers for calls and SMS
- Good for long-term stays or residents
Both connect to the same reliable Singapore networks with strong 4G and 5G coverage.

How to choose the right eSIM for your Singapore trip
The best eSIM for Singapore depends on how long you’re staying, how much data you need, and how you plan to use it. Most travellers choose short-term plans for navigation, messaging, and browsing, while remote workers or long-term visitors prefer larger data packs that can handle video calls and hotspot use.
Things to consider when choosing your eSIM:
📱 Device compatibility: Make sure your phone supports eSIM (iPhone XR+, newer Androids, or Pixels).
🌏 Travel plans: Choose a regional or global plan if you’re visiting nearby countries like Malaysia or Indonesia.
📶 Coverage: Look for providers that connect to reliable Singapore networks such as StarHub, SIMBA, Singtel, or M1.
💬 Support: Check if the provider offers in-app support or a help centre for quick troubleshooting.
💾 Data needs: Light users may only need 3–5 GB per week; frequent hotspot users will need more.
