Singapore Travel SIM & eSIM Guide: Ditch Roaming Charges

Planning a trip to Singapore? Whether you're visiting the Lion City for business, spending a few days during a layover, or enjoying a city break, getting a local SIM card or eSIM is a smart choice. Roaming charges from UK mobile providers can be extremely expensive, so using a local eSIM or SIM card is the easiest way to stay connected and save money while you're in Singapore.

In this article, we break down your options for mobile data in Singapore, from trusted eSIM providers to local SIM cards you can buy on arrival. We've partnered with 45+ reliable eSIM brands to help you find the right plan for your trip. I visited Singapore earlier this year and personally tested several providers to compare speed, reliability, and ease of use. Based on that experience, we'll share our top 3 eSIM options, each suited to different needs, whether you're looking for the lowest price, the most data, or the best plan for short business trips or layovers.

For most trips to Singapore, we recommend using a travel eSIM: it's by far the most convenient option and lets you skip the queues and paperwork. While you can buy a local SIM card at Changi Airport, prices are not clearly advertised, so you'll need to ask around at each counter. Most plans are quite large and often more than you need for a short layover or business trip. There are also SIM cards with regional roaming for travellers exploring more of Southeast Asia, but these rarely offer competitive value. For short-term visitors, a travel eSIM usually provides better value, instant connectivity, and a much smoother experience.

If you're travelling to Singapore, the chances of getting a slow eSIM connection are very low. Many eSIM providers resell international data plans, and while these often rely on global infrastructure, Singapore itself is one of Asia's major internet hubs. That means if you buy an eSIM specifically for Singapore, your data is likely routed locally, resulting in a fast and stable connection. In many cases, you'll also get a local IP address, which can be useful for location-based apps or services.

Installing an eSIM is incredibly simple. The exact process may vary slightly depending on the provider, but in most cases it involves either using an app or scanning a QR code to get set up. Once you've completed these quick steps, you'll be ready to use mobile data seamlessly during your trip.

Unlimited data eSIM for Singapore

You'll find several unlimited eSIM options for Singapore on Find Your eSIM. These plans are ideal if you want to stay connected without worrying about your data usage. Just keep in mind that all unlimited eSIMs come with a fair use policy (FUP), which may reduce your speed after a certain threshold.

Most unlimited plans come with a daily data limit, typically between 1 and 5 GB, which is more than enough for browsing, navigation, messaging, and general use while in Singapore. However, streaming full-length films or live sports is often unrealistic, as once you hit the cap, your speed is usually throttled or your connection may even be paused for the rest of the day. That's why it's important to read the fair use policy (FUP) carefully before purchasing. If a provider doesn't clearly state their limits, or uses vague terms like "if necessary" or "some carriers may reserve the right to apply a Fair Usage Policy", that's usually a red flag, and a strong reason to consider other options. A trustworthy eSIM provider should always be upfront about what you can and can't expect.

Also check whether hotspot usage is allowed; this can be especially important for business travellers who rely on tethering their laptop or other devices.

Local networks in Singapore

These are the three major mobile networks in Singapore:

• Singtel – Singapore's largest and oldest telecom provider, known for its excellent coverage and strong reliability.
• StarHub – A well-established competitor offering solid nationwide coverage and attractive data plans.
• M1 (MobileOne) – A popular choice among locals, offering good value and dependable performance across the island.

Singapore has one of the best mobile infrastructures in the world, and all three networks provide fast and stable connections throughout the city-state. While Singtel is often viewed as the market leader, the differences in performance between the networks are minimal.

Most eSIM providers automatically connect to one or more of these networks, ensuring you get great coverage no matter which eSIM you choose. Whether you're in the city centre, at the airport, or exploring neighbourhoods like Sentosa or Marina Bay, you can expect consistently strong signal quality.

Curious about signal strength in specific areas? You can explore network coverage using tools like nPerf and Opensignal.

Buying a local SIM card

If your phone supports eSIM, it's by far the fastest and easiest option. After a long flight, there's no need to queue at a counter with your passport to choose a data plan. With an eSIM, you're online instantly and ready to go. Not eSIM-compatible? No worries, there are plenty of alternatives.

Singapore makes it easy to buy a physical SIM card. Since English is widely spoken, you'll have no trouble getting assistance wherever you go. If you want to get connected right away, you can pick one up at Changi Airport. Just keep in mind that airport prices include a markup and are usually higher than in the city.

When you arrive at Changi, you'll find multiple SIM card vendors in the baggage claim and arrivals area; this is true for all terminals. Data plans are typically advertised on large boards, but prices are often not clearly displayed. That makes comparison difficult; you'll have to ask each vendor about their current rates. Prices at the airport tend to be high: expect to pay between £26 and £43 for a 100 GB plan. Smaller data packages are usually not available.

There are also SIM cards available with regional roaming across multiple Southeast Asian countries. These can be convenient if you're travelling through the region, but they are often significantly more expensive than buying local SIMs in each country.

Tip: if possible, wait until you're in the city. Stores like 7-Eleven often carry more affordable SIM cards, and that can save you quite a bit of money.
