Airalo

Airalo comes first in the list of the best esim for Singapore. The Airalo Singapore eSIM has you covered with a range of data plans suitable for short layovers or extended adventures. Airalo is the world’s largest esim marketplace, known for its budget-friendly rates and reliable coverage on major local networks. Singapore uses Singtel’s 4G/LTE network. It’s a traveller favourite for staying online without breaking the bank.

• Website: Airalo

• Reliable connectivity via Singapore’s top carrier (great for city and offshore islands)

• A variety of plan sizes (from 1 GB up to 20 GB) to suit different needs

Cons:

Holafly

Holafly is the go-to eSIM provider for those who want unlimited data and are willing to pay a premium for peace of mind. If you plan to Instagram your entire trip or do Zoom calls from the Marina Bay Sands, Holafly’s Singapore esim offers unlimited data plans, so you never run out (keep an eye on fair use limits). It’s a convenient option with easy activation – think of it as the “all-you-can-eat” data buffet for travellers.

Website: Holafly
Best for: Heavy data users who want unlimited internet without worrying about usage caps

Key Features:

• Unlimited data on all plans (no fixed GB limits – browse and stream freely)

• 5 G-capable eSIM on Singapore’s Singtel network (fast speeds in 5G areas)

• Hotspot/tethering allowed (capped at 500 MB per day for sharing)

• 24/7 customer support in multiple languages for any setup issues

• Easy activation via email, QR code, or the Holafly app (install before or upon arrival)

Pros:

• Truly unlimited data

• Simple setup and eSIM activation process

• Allows limited data sharing via a hotspot 

• Responsive customer service if you need help during your trip

Cons:

• Significantly more expensive than data-capped eSIM options

• Fair Use Policy applies – excessive use may lead to speed throttling (so “unlimited” isn’t always full-speed)

• No local phone number (data only), but with unlimited data, you can use Voip for calls

Available Plans (Unlimited Data / Validity / Price in USD):

• 1 Day – $6.90

• 3 Days – $12.90

• 5 Days – $20.90

• 7 Days – $29.90

• 10 Days – $36.90

• 14 Days – $47.90

• 20 Days – $61.90

• 30 Days – $74.90

Note: “Unlimited” comes with a fair-use limit – for example, if you binge 4K videos all day, your speed may temporarily slow down. But for normal travel use, maps, social media, and Uber,  it’s effectively unlimited.

Ubigi

Ubigi is a lesser-known gem that often offers excellent short-term data deals. Backed by a telecom services company, Ubigi’s esim for Singapore combines affordability with high-speed access, including 5G where available. It’s especially great if you only need a small amount of data for a brief stay – think layovers or a 2–to 3–day business trip – but they also have larger plans. Setup is straightforward via the Ubigi app, making it a quick option to get online upon arrival.

Website: Ubigi
Best for: Travellers on short trips who want a cheap, low-volume data plan 

Key Features:

• Offers very low-cost mini plans (1 GB for only $ 4)

• 5G supported in Singapore, utilising Starhub/Simba networks for fast data

• A user-friendly app that often comes pre-installed on esim-compatible devices

• Global coverage in 190+ countries 

Pros:

• Ultra affordable for small data needs 

• 5 G-ready eSIM- enjoy Singapore’s speedy networks if you have a 5G device

• Simple purchase/activation process; no ID registration required

• Can reuse the eSIM profile globally,  convenient for multi-country trips

Cons:

• Limited plan variety for Singapore – primarily small and mid-sized data packs

• No unlimited data option and not the absolute cheapest on large GB plans (others may beat their high-volume prices)

• Data-only (like most travel eSIMs, you won’t get a local phone number or voice/SMS service)

Available Plans:

• 1 GB – 7 Days – $4.00

• 3 GB – 15 Days – $8.00

• 10 GB – 7 Days – $14.00

• 10 GB – 30 Days – $16.00

• 25 GB – 30 Days – $32.00

Nomad

Nomad lives up to its name by catering to the digital nomads and avid travellers among us. This esim provider offers a wide variety of plans for Singapore, from small 500 MB refills to large 50 GB packages, and even special “daily” plans that provide a fixed amount per day. Nomad’s appeal is its flexibility and user experience: the app makes it easy to purchase, install, and even recharge another plan if you run out of data.

Website: Nomad
Best for: Tech-savvy travellers who want a wide range of plan choices and a seamless app experience

Key Features:

• Extensive selection of Singapore eSIM plans

• Both fixed-data plans and “daily” plans (e.g. X GB per day for Y days) for more customised usage

• User-friendly Nomad app (ios/Android) for buying and installing eSIMs in a few taps, and no QR code needed

• Multi-country regional plans are available (e.g. a combined Singapore-Malaysia-Thailand plan) for cross-border travellers

Pros:

• Competitive pricing on many plans (as low as USD 4 for 1 GB)

• Ability to top up with an extra plan through the app if you need more data mid-trip (no swapping eSIMs)

• Supports data sharing/tethering to other devices (so your laptop or travel buddy can use your hotspot)

• Generally reliable performance via local networks (Nomad’s eSIM connects to Singtel in Singapore, which gives good coverage)

Cons:

• No unlimited data option (all plans have fixed data, so heavy streamers might need to buy large packages or recharges)

• Mixed user feedback on speed – mostly good, but a few experienced slow connections or setup quirks

• Like others, no voice/SMS included (it’s data-only), which means no receiving SMS codes unless you keep your primary SIM active

Available Plans:

• 1 GB – 7 Days – $4.00

• 3 GB – 30 Days – $7.00

• 5 GB – 30 Days – $10.00

• 15 GB – 30 Days – $20.00

• 30 GB – 30 Days – $35.00

• 50 GB – 30 Days – $49.00

Nomad also offers one of the cheapest esim deals for Singapore: $2.50 for a 1-day “daily plan” with 500mb. Handy if you only need mobile data on the last day of your trip.

Flexiroam

Flexiroam is a veteran in the global SIM space and a great choice if your trip to Singapore is just one stop among many. Catering to over 170 countries, Flexiroam’s esim lets you switch between local, regional, and global plans all in one place. For Singapore specifically, their plans aren’t the cheapest for large data bundles, but they offer unlimited plans and the convenience of managing everything in one app.

Website: Flexiroam
Best for: Frequent travellers or multi-country trips (flexible plans that can be used in Singapore and beyond)

Key Features:

• Coverage in 170+ destinations worldwide, a single Flexiroam eSIM can be used almost anywhere with the right data plan

• Offers both fixed data plans and unlimited data plans for Singapore

• Data sharing is allowed on fixed plans (you can hotspot to other devices), though it is  not available on unlimited plans

• App for ios/Android to buy or switch plans easily; also provides 24/7 customer support if issues arise

• Known for innovative extras and often runs promos (like “$X per day” deals)

Pros:

• One eSIM profile can cover many countries – perfect if Singapore is part of a larger Asia trip

• Easy to swap between limited and unlimited plans as needed

• Able to tether on limited plans so that you can share data with your laptop or a friend’s phone during your travels

• Long validity options for data (e.g. 180-day global plans) – useful for business travellers or expats needing a backup data line

Cons:

• Prices for single-country Singapore plans are higher than most competitors (you pay a premium for the flexibility)

• Unlimited plans have no hotspot sharing (to prevent abuse)

• No local number for calls/SMS, and the network is auto-selected (no control over which Singapore provider it uses)

Available Plans:

• 1 GB – 7 Days – $7

• 3 GB – 30 Days – $17

• 5 GB – 30 Days – $23

• 10 GB – 30 Days – $36

• 20 GB – 30 Days – $52

• Unlimited – 5 Days – $19 

If you’re just using Singapore, Flexiroam might not be the cheapest option, for example, 5 GB for $23 compared to Airalo’s 5 GB for $12. But if you want one eSIM for all of Southeast Asia, the convenience can outweigh the cost.

Saily

Saily is the new kid on the block, turning heads with shockingly cheap esim plans. Created by a team from Nordvpn in 2023, Saily aims to reel in travellers with rock-bottom pricing on data packs. Don’t let the low prices fool you – it offers coverage in over 200 countries, including Singapore. The service quality is solid, especially in urban areas. If you’re travelling on a shoestring budget or need a small amount of data to get by (think texting, Grab rides, and a bit of Instagram), Saily could be your best friend.

Website: Saily
Best for: Budget travellers and short trips – anyone looking for the absolute lowest cost for basic connectivity

Key Features:

• Incredibly low pricing for Singapore plans (prices start at under $2!)

• Offers local eSIM plans in Singapore with 1 GB, 3 GB, 5 GB, 10 GB, 20 GB options (7 or 30-day validity)

• Seamless activation through the Saily app; very user-friendly for eSIM beginners

• Global reach: 200+ destinations covered if Singapore is just one stop (but note: no regional “Asia” bundles yet, only single-country or global plans)

• Backed by a reputable tech company (Nordvpn team), so security and privacy are a given priority

Pros:

• Cheapest eSIM for Singapore in the market, e.g., 1 GB for $1.89 (7 days) with current deals

• Great value larger plans too (e.g. 5 GB for around $9.99)- you’ll often pay half of what other providers charge

• Clean, intuitive app and installation process – you can go from purchase to connected in minutes

• Transparent pricing with no hidden fees, plus frequent promo codes 

Cons:

• No unlimited data option (if you need endless data, you’ll have to buy a bigger fixed plan or look at Holafly/Yesim)

• Focuses on single-country plans – lacks multi-country regional passes (if you’re touring multiple countries, you’d need separate plans or a global plan)

• A newer provider means a shorter track record, though so far, reviews are positive (and it’s hard to argue with the price!)

Available Plans:

• 1 GB – 7 Days – $3.99 (often discounted to $ 1.89 for new users)

• 3 GB – 30 Days – $6.99

• 5 GB – 30 Days – $9.99

• 10 GB – 30 Days – $15.99

• 20 GB – 30 Days – $12.34 

With Saily’s prices, you might double-check if there’s a catch. But it’s truly that cheap. The catch, if any, is simply that Saily is trying to gain market share- lucky for travellers!

Airhub

Airhub is like a marketplace bazaar for eSIM- instead of offering just one or two plans, Airhub aggregates plans from multiple providers. The result? Some of the best value data deals in Singapore, and even options that include voice calls (a rarity in the eSIM world). Navigating Airhub’s site can feel a bit overwhelming due to the sheer number of choices, but if you’re willing to browse, you can snag a fantastic deal.

Website: Airhub
Best for: Travellers seeking maximum data for their money, or those who want an eSIM plan with local call/SMS capabilities

Key Features:

• Marketplace model with multiple plans – find anything from small 7-day packs to large 30-day bundles (and even regional or global options)

• Some plans include voice minutes and texts, not just data (e.g. Airhub has options that come with a phone number, useful if you need to receive SMS codes)

• Supports 4G/LTE data on Singtel’s network in Singapore (good coverage; 5G not yet available on these plans)

• Competitive pricing – by shopping around on Airhub, you’ll find very low cost per GB on many plans

• No need to install multiple eSIM profiles; you can purchase different plans in one place and switch as needed

Pros:

• Incredibly cheap deals for Singapore data, e.g. 3 GB for $5 (7 days), are practically unbeatable.

• Larger data packages offer great value (e.g., 12 GB for $11.50), ideal for heavy data users staying longer.

• Unique option for plans with calls/SMS included, handy if you must have a local number for OTPS or local calls

• One-stop shop: you can compare multiple sub-providers’ offers and pick what fits your needs and budget

Cons:

• The website interface isn’t the most user-friendly. Sorting or filtering plans are limited, so you might need to scroll through a list to find your perfect match.

• No dedicated Airhub mobile app (as of writing), you purchase through the website, which is functional but less slick than some app-based competitors

• Data-only on most plans (only certain plans include voice/text, and those might be more expensive or limited in availability)

Available Plans:

• 3 GB – 7 Days – $5.00

• 4 GB – 30 Days – $6.50

• 7 GB – 30 Days – $8.50

• 12 GB – 30 Days – $11.50

• 23 GB – 30 Days – $26.50

Yesim

Rounding out our list is Yesim, a traveller-focused eSIM provider whose name says “YES, I’m connected!” (okay, it stands for “Yes SIM”). Yesim strikes a great balance between unlimited data offerings and reasonable pricing, making it a top choice for users who want a lot of data but don’t want to pay Holafly-level prices. In Singapore, Yesim offers both fixed data packs and unlimited plans that last up to 30 days. It’s known for an easy app experience and even throws in perks like a free VPN on ios.

Website: Yesim
Best for: Travellers seeking unlimited data at a better price point (heavy data users who want a deal), or anyone wanting a user-friendly eSIM with bonus features

Key Features:

• Unlimited data plans available for 1, 7, 15, or 30 days in Singapore

• Affordable fixed-data plans as well (for example, 3 GB and 5 GB options in the $ 12-$30 range)

• Yesim app offers one-tap eSIM installation, plus extras like a built-in VPN (for ios users) and 24/7 support

• Coverage in 200+ countries with a single esim. You can buy local plans for each or multi-country packages as needed

• Supports 5G where available and typically connects to strong local networks (in Singapore, it will latch onto a major carrier, often Singtel or Starhub, to ensure good service)

Pros:

• Unlimited data plans that are cheaper than many competitors- e.g. 30 days unlimited for $64 (vs $74.90 on Holafly)

• Fixed plans are reasonably priced too (e.g. 3 GB for $ for-$11), giving travellers flexibility if they don’t need unlimited

• Smooth user experience with the Yesim app–purchase, install, and manage your eSIM easily (no tech headaches)

• Extra perks: free daily 500 MB hotspot sharing even on unlimited plans, and a complimentary VPN service for secure browsing on public Wi-Fi

Cons:

• “Unlimited” plans have a Fair Usage Policy (like others, they may throttle speeds if you exceed a certain high threshold of usage per day)

• Data-only – no local phone number or voice minutes included (Yesim is purely for data, so use WhatsApp/Skype for calls)

• While prices are good, they’re not the absolute cheapest for small plans (very budget users might still find Saily a bit cheaper for 1–5 GB needs)

Available Plans:

Unlimited Data Plans:

• 1 Day – $7.90

• 7 Days – $31.62 

• 15 Days – $42.91

• 30 Days – $60.98

Fixed Data Plans:

• 3 GB – 7 Days – $11.29

• 5 GB – 30 Days – $24.84 (or- EUR 22)

• 10 GB – 30 Days – $38.39

• 20 GB – 30 Days – $39.52 (special offer-€35)

Yesim’s unlimited plans let you roam free online. Just remember, “unlimited” doesn’t mean “infinite speed 24/7” – extremely heavy usage might trigger throttling to 1 Mbps as a fair use measure. 

Guide for Choosing the Right eSIM for Singapore

Planning to use an eSIM in Singapore? Here are the key things to check before buying:

• Network Coverage: Ensure your esim connects to strong local networks, such as Singtel or Starhub, for reliable coverage, even in remote areas like Sentosa. Brands like Airalo and Ubigi do well here.

• Device Compatibility: Most newer phones support esim, including the iPhone XR+, Pixel 3+, and Samsung S20+. Double-check your model before buying.

• Data Plans: Match the plan to your needs, light, moderate, or heavy data use. Airhub offers flexible plans ranging from 3GB to 20 GB+.

• Price: Compare costs! Saily is great for budget travellers, with plans from $1–$2. Big names may charge more for the same data.

• Unlimited Data: Need constant access? Holafly and Yesim offer unlimited plans, but be aware of fair use limits.

• Validity: Choose a plan that covers your full trip. Nomad and others offer 7-day, 15-day, and 30+ day options.

• Easy Setup: Look for QR code activation or app-based install. Saily and Holafly offer a smooth, fast setup with helpful guides.

Why Choose eSIM in Singapore?

• Instant & Easy: No physical SIMS or kiosks. Just download and activate online.

• Save Money: Avoid high roaming charges. Use affordable local rates instead.

• More Flexibility: Switch providers anytime, store multiple plans, and travel across countries with ease.

• Eco-Friendly: No plastic SIMS, which means less waste.

• Always Connected: Stay online for maps, Grab rides, food spots, and Instagram-worthy moments.
