1. Saily - Our Overall Top Pick

Saily is one of those companies that just thinks of everything. The eSIM offers all the features you could ask for (range of prepaid and unlimited plans, super reliable data, unlimited hotspotting), and a whole lot of bonus perks that you probably didn’t even realize you need.

The main reason we love Saily is that it’s both a cybersecurity tool and an international eSIM all rolled into one. It comes with a built-in VPN and 115+ virtual locations, an ad blocker to save you data, and web protection tools to block malicious websites.

The prepaid plans go from 1 to 20GB, and if you want even more data, they have unlimited options for 5, 10, 15, 20, 25, or 30 days. In other words, Saily has you covered in more ways than one.

Specifications

• Plan Options: 1GB, 3GB, 5GB, 10GB, 20GB, or unlimited data
• Data Speed Throttle: 5GB/Day without a speed limit
• Built-In VPN? Yes
• Pros: Extremely reliable data, and comes with built-in security features
• Cons: Limited higher data plan options

2. Airalo - Best for New Users

Airalo is a bit of an OG in the eSIM space that also happens to be a Singapore-based company. So, it shouldn’t be too much of a surprise that their eSIMs for travelling in Singapore are top quality. They are partnered with StarHub, a local network with some of the strongest coverage in the country. That means fast and reliable data is essentially a guarantee.

Airalo is also a great choice for first-time eSIM users. Purchasing, installing, and activating their eSIMs really couldn’t be a smoother user experience, plus they always have new user discounts and offers. Plans start from $4.60 for 1GB, or 5 days of unlimited data for $18.99. As a bonus, when you buy an Airalo eSIM, you get “Airmoney” to use toward future purchases.

Specifications

• Plan Options: 1GB, 3GB, 5GB, 10GB, 20GB, 50GB, or unlimited GB
• Data Speed Throttle: After 3GB per day
• Built-In VPN? No
• Pros: Super easy to install and activate
• Cons: On the upper end of the price range

3. Ubigi - Best for Monthly Plans

Unlike other eSIM providers, Ubigi has not only prepaid and unlimited data plans, but also monthly options for those of us staying more than 30 days in Singapore.

There’s the monthly rolling plan that gives you 20GB for $19/month. It’s cancellable after three months, and doesn’t require ID to set up. The second long-term option is the 12-month plan for $45. With this, you pay upfront, then get 5GB/month x 12, and the monthly data automatically renews. This would be ideal for anyone who’s not in Singapore all the time, but is visiting frequently.

Another thing we like about Ubigi is that they work with both StarHub and Simba data networks. That means users have an even better chance of 5G data speeds across Singapore.

Specifications

• Plan Options: 1GB, 3GB, 5GB, 10GB, 20GB, 50GB, or unlimited GB
• Monthly Plans: 20GB/month rolling, or 5GB/month annual plan
• Built-In VPN? No
• Pros: Big range of plan types to choose from, and multiple network partners
• Cons: The data throttle rules are confusing and change depending on which plan you choose

4. BNESIM - Most Budget Friendly Data

BNESIM is on this list for two major reasons: its data is cheap, and it has non-expiring options. That basically means that while most eSIMs only give you a short window to use up your data, with BNESIM, that timer never runs out.

We also love that BNESIM offers non-expiring prepaid plans up to 100GB ($52), which is a very enticing alternative to unlimited plans that throttle you after 2GB for anyone who wants a lot of data.

While we’re on the subject, we should make clear that if you’re looking for unlimited data, BNESIM probably isn’t for you. They only have one 10-day plan option, which also doesn’t include hotspot data sharing.

Specifications

• Plan Options: 1GB, 3GB, 5GB, 10GB, 20GB, 50GB, 100GB, or unlimited GB
• Plan Lengths: 30 days or non-expiring
• Built-In VPN? Yes (BNE Guard)
• Pros: The cheapest prepaid data plans that don’t come with an end date
• Cons: Unlimited plans are very lackluster

5. AloSim - Best for Calls and Texts

AloSim is one of the only eSIM providers in the game that actually includes an international phone number along with data. The number is provided by Hushed and comes with $3 in free credits for calls and texts. You can then top up credits as needed.

In terms of the actual data, AloSim is pretty competitively priced, e.g., you can get 10GB of data for $16, 20GB for $23, or unlimited plans starting from $17 for 3 days. AloSim is also another provider that works with StarHub for some of the best 5G coverage in all of Singapore.

AloSim also has a really good range of unlimited plan lengths between 7 and 30 days. We wish the 2GB/day high-speed data limit were a little higher, but we do appreciate that there aren’t any hotspot limitations.

Specifications

• Plan Options: 1GB, 2GB, 3GB, 5GB, 10GB, 20GB, or unlimited GB
• Data Speed Throttle: After 2GB per day
• Built-In VPN? No
• Pros: International number included for calls and texts
• Cons: Data speed throttle could be higher

How Much Data Do You Need in Singapore?

Singapore is one of the easiest countries in the world to stay connected. Between fast mobile networks and tons of public WiFi, most travelers don’t need a huge data plan…although the right amount really depends on how you plan to use your phone.

We’d say that for the average traveler, 3GB to 5GB for a week is usually more than enough. That will keep you more than covered for things like checking directions on Google Maps, booking rides on Grab, or sending messages on WhatsApp.

If you’re a digital nomad or planning to hotspot your laptop to work, you’ll want more data. Video calls, cloud apps, file uploads, and general work tasks can add up quickly. In that case, 10GB to 20GB is a safer range, or even an unlimited plan if you don’t want to worry about running out. Just keep an eye on the data throttle limits (or think about getting a pocket WiFi).

The good news is that Singapore has tons of free WiFi, so you may not need much mobile data at all. For some people, 1GB might actually be enough for your whole trip…just make sure to use something like Saily, which has a built-in VPN for when you’re connecting to public networks to keep your connection safe.
