Known for its blend of East Asian cultures and cosmopolitan city life, Singapore isn't popular with tourists without reason. If you're planning to visit the country soon, it should come as no surprise that you won't be able to call, SMS, or access the web on the go with your smartphone as you usually would at home, and if you do manage to get connected via roaming, it can result in hefty additional charges.

However, none of this means you should leave your smartphone at home. If your device is a newish model (i.e., from 2019 or later), there's a good chance it'll support an eSIM. These nifty digital SIM cards can be downloaded and installed before you travel. They promise blazing-fast internet in Singapore at a very low cost compared to roaming and great convenience compared to physical SIMs.

In this guide, we explore everything you have to know about eSIMs in Singapore and what the best deals might be for you, specifically Holafly for unlimited data, Airalo for low-cost limited data, and GigSky for a free 100 MB test eSIM and all-round affordability. But if you'd like to skip ahead and find the best deal instantly, use our free comparison engine below.👇

Compare all 206 eSIM data plans for Singapore in just a few clicks:

As we'll explore in more depth in this guide, when choosing an eSIM, you have two options. The first option is to go through a digital eSIM provider, and the second is to purchase an eSIM directly from your network provider or carrier. We strongly recommend the first option. After all, with reputable online providers, you can always be sure you'll get good support, excellent rates, and quality instructions that normally exceed those of the big carriers.

According to our review and comparison of the best options on the market, the best four eSIM providers for Singapore are Holafly, Airalo, GigSky, and Yesim.

Here are a few key facts:

Best Overall: Airalo

Airalo is an excellent eSIM provider for Singapore. Its online platform offers global access to eSIMs through collaboration with big local telecom providers. In Singapore, for example, Airalo works directly with Singtel to provide you with high-speed coverage directly from their networks, wherever you are in the country.

Once-off prices for eSIMs for Singapore range from $4.50 to $26 and include between 1 GB and 20 GB of data. Ordinary travellers should be able to get by with these amounts without any problems. Setting up and activating your eSIM happens entirely on your smartphone, and it's very quick. In our test, we just took two minutes (watch our how-to video on YouTube to see how it's done). Moreover, you can easily top this up via the Airalo app if you start running low on data during your trip. This lets you save time and hassle compared to buying a physical SIM, where you'd usually need to stand in line at the counter to buy or top up your card or package.

We recommend Airalo in general, especially if you travel often. The service provides an excellent connectivity companion while you're abroad. To learn more about this excellent eSIM provider, look at our in-depth Airalo review.

Best For Unlimited Data: Holafly

Holafly is another trusted eSIM service which only provides packages with unlimited data to dozens of countries worldwide. Although these packages cost quite a bit more than the smaller Airalo packages, in return, they offer the certainty that you'll never use up all your data.

For trips to Singapore, Holafly's data packages cost between $21 and $139 once off and are valid from five to 90 days. Like Airalo, Holafly also works with domestic carriers, so you'll get coverage like a local no matter where you travel in the country (although in remote regions, coverage can become spotty).

info icon

Although Holafly offers unlimited data in most countries, including Singapore, if you're a globetrotter, it's worth keeping in mind that Holafly offers limited data plans to some other destinations. Be sure to check their website or app before traveling to a new country to confirm whether Holafly's unlimited packages apply.

Although Holafly's packages are generally great if you'd like uncapped access to the web, it's worth remembering that most travellers don't usually need such a large sum of data and that normally, 5 GB to 10 GB, at most, should be enough for everyday travel needs in Singapore like navigating, browsing, and using social media. Moreover, your speeds might be temporarily throttled if you use a very extensive amount of data (e.g., for non-stop HD streaming or downloading large files). During our test in the UK, this happened to us at around 4.5 GB of usage. Sadly, Holafly's fair use policies don't clearly outline when networks throttle speeds since it comes down to the individual network or carrier and the country you're browsing in.

If you're curious, we tested Holafly extensively to see if its data plans really live up to their 'unlimited' promise. The short answer? Yes, but there are a few things you should know. Take a look at our Holafly review to find out what they are.

Best For a Free 100 MB Test: GigSky

GigSky is a popular US-based eSIM provider that offers a unique opportunity: it lets you download and install a free eSIM with 100 MB of allowance to test how eSIMs work without being obligated to pay more once you've used up your data.

Like Airalo, GigSky offers fixed data plans (normally just 1 GB, 3 GB, or 5 GB) in around 200 destinations worldwide, including Singapore. And like Holafly, it also offers unlimited plans. In addition, GigSky offers regional and global plans, with all of its data allowances competitively priced and its rates neck-in-neck with those of the other providers on this list.

Most interestingly (unlike Airalo and Holafly), Gigsky offers special data plans for flights and cruises. Although they're pricier than the normal plans, they could be useful if you'd like to connect in the air or at sea.

Regardless of what kind of data plan you're looking for, GigSky probably has you covered—and at great rates to boot. Sign up now for a no-obligation free 500 MB and top up your data later if you need more.

Another Reliable Alternative: Yesim

A smaller and newer company than Airalo and Holafly, Yesim is a Swiss-based eSIM provider offering highly-rated eSIMs for countries around the globe. Their website and app are simple, straightforward, and easy to use, and over 300,000 customers have chosen their eSIMs so far.

Like its larger competitors, Yesim gives you a SIM card connecting to local carriers while you're abroad. It can be installed quickly and effortlessly right from the app or via a QR code sent to your email after purchase. Interestingly, alongside its eSIM service, Yesim also offers a virtual number service that allows you to get an online-only US (+1), Canadian (+1), or Israeli (+972) mobile phone number to use for apps like WhatsApp, Telegram, Instagram, OpenAI, Binance, Tinder, or TikTok. These virtual numbers can be used for a flat fee of $2.75 per month.

Going back to eSIMs, Yesim's packages typically cost between $7 and $28 for 3 GB to 20 GB, but only the 10 GB and 20 GB data plans last longer than 30 days (some plans up to 60 days are possible to purchase). In our opinion, this makes Yesim's offers slightly less attractive than Airalo's for travel in general.

However, it's worth remembering that Yesim's prices are often fractionally lower per gigabyte, so if you're looking for the best deal, make sure you visit Yesim's website and compare their prices to Airalo's,

As you'll see, the three are very competitive, with differences normally being slight. If you'd like to compare Holafly and Airalo directly, take a look at our side-by-side review of the two too.

Do I Need a SIM Card in Singapore?

No, you don't need a SIM card as a tourist in Singapore, but having one will enable you to make phone calls and SMSes and not to rely solely on public or hotel WiFi to access the web.

A good place to start would be to review your contract from your mobile network provider before you travel to Singapore. Most contracts are limited to use just within your home country (or within the European Union if you live in an EU country). For all other countries, so-called 'roaming charges' typically apply. However, there is one exception: specific contracts sometimes allow you to use your data worldwide. If you have a global internet contract, you can also use it in Singapore without unexpected roaming charges.

💳 Planning to use your credit or debit card on your Singaporean trip? You'll probably pay more than you think in hidden exchange rate fees every time you tap your card or withdraw cash. Get a free global account and debit card with Revolut to avoid these fees and save money. Check out our ranking of the best prepaid travel debit cards to find out more about how you can save.

Otherwise, although precise roaming charges differ according to your network provider, the fees for using mobile internet in Singapore are typically around $2 or $3 per 6 MB (six megabytes) of data used, though they could be higher still. For example, if you wanted to download an average-sized app from the Google Play Store onto your Android smartphone, you'd use around 24 MB and pay $8 to $10 in roaming charges. It should, therefore, be clear that roaming with your regular SIM card in Singapore is generally not worthwhile and can lead to enormous costs. As we'll see in a moment, it's significantly cheaper to purchase a local Singaporean SIM card once you arrive or, better yet, an eSIM before you travel.

What Are eSIMs, Anyway?

Simply put, eSIMs are regular SIM cards that don't require inserting an actual microchip into your device while providing the same benefits. Newer smartphones (but also smartwatches, tablets, and other devices) can be equipped with eSIMs, and since you don't need an actual SIM card to install an eSIM, you can also get one before your trip to Singapore. To do this, all you have to do is visit an online eSIM service, purchase the eSIM you want, and follow the instructions to download and install it onto your device.

Like regular SIM cards, prepaid eSIMs come bundled with a certain fixed amount of data, SMSes, or telephone minutes, which you can use at your leisure while travelling. You get to choose the package you want, and you can generally also extend your eSIM's validity easily right from an app.

Pros of Using an eSIM

In general, eSIMs have numerous advantages and are often a better alternative to using a regular SIM card for most tourists. In our opinion, the most significant advantages include:

  • internet immediately upon arrival in Singapore,
  • no negotiating with SIM card sellers at the airport,
  • transparent and fair pricing,
  • online extension is often possible,
  • credit card payment is possible,
  • local telecom provider networks are used.

In our opinion, there are only a few reasons against using an eSIM when travelling to Singapore (which we'll discuss below), and in most instances, we're sure that it's a far better deal than using your normal SIM card from your home country on Singaporean networks.

Cons of Using an eSIM

As we've already seen, eSIMs have very few drawbacks and are an excellent option for accessing mobile internet on your Singaporean vacation.

However, one disadvantage is the slightly higher upfront cost than physical SIM cards. That said, eSIMs are still comparatively cheap, especially for use in Singapore from abroad. In our opinion, the significantly higher level of comfort and the possibility of having access to the internet immediately upon arrival are worth the extra pennies. Another disadvantage is related to installation, where the process may be unfamiliar to you if you've never installed an eSIM before. However, if you follow the instructions carefully, you'll be fine.

Finally, there's the issue of compatibility: not all devices support eSIMs. If your device was released before late 2019, we recommend double-checking on the internet or contacting a representative from an eSIM service to confirm whether your device is compatible before you purchase an eSIM. In general, the following devices will support eSIMs though:

  • iPhone 11 or later
  • iPhone XS, iPhone XR, or iPhone SE
  • iPad 7th generation or later,
  • Galaxy S20 or later
  • Google Pixel 3 or later
  • and many other devices (see our full list of compatible devices)

Can I Call From Singapore With an eSIM?

Yes, you can call abroad from Singapore with an eSIM, but once again, using your regular network provider and SIM card could result in surprisingly high calling charges at the end of the month (we've personally encountered as high as $4 per minute!). Fortunately, you can call abroad without the high costs, and there are three ways of doing this. We go through each below:

1. Voice-Over-IP (VoIP) With Data

In most cases, eSIM packages are loaded with mobile data, not with minutes or airtime. However, using your data, you can use web-based apps like WhatsApp, Google Meet, Skype, Telegram, Facebook Messenger, FaceTime and others to stay in touch with family and friends abroad while in Singapore.

2. eSIMs With Airtime

Some eSIM services offer talk and text packages alongside normal data packages. These allow you to make direct phone calls or SMSes via local networks in Singapore to your home country for only a slightly higher fee than regular data packages. Not all eSIM services offer this service though, but some, like Wraptel, do.

3. International Calling Apps

If you plan to make calls from Singapore (or anywhere else abroad) fairly regularly, then your most reliable and affordable option will be to use a third-party app. In our opinion, Rebtel is by far the best service out there, offering low rates and providing you with local Singaporean phone numbers with which you can make calls abroad as though they were completely domestic.

Although it's popular, we typically don't recommend using Google Fi for this purpose unless you plan to go back and forth from the United States regularly (since Google Fi is only available to Americans and will not work if you spend over 90 days abroad per year). In general, Rebtel's rates are more affordable than Google Fi's too. To learn more about our first-hand experience with Google Fi, look at our in-depth review.

Recap: All About eSIMs in Singapore

Are you planning a trip in Singapore, and do you have a modern smartphone? Then, you should certainly at least consider getting an eSIM. In our opinion, they offer almost nothing but advantages and are generally far superior to using your regular SIM card.

To find the right provider for eSIMs in Singapore, you should compare the available options. As we've seen, we recommend looking primarily at the network provider and the price. Depending on how long you want to stay in Singapore, Airalo, Holafly or possibly Yesim are the best choices. To recap, here are what each can offer you:

  1. Airalo: Best eSIM for Singapore overall.
  2. Holafly: Best eSIM for unlimited data.
  3. Yesim: Good alternative to Airalo,
  4. GigSky: Best free eSIM to test,
  5. Rebtel: Best calling service for international calls.
