Best eSIM for Singapore 2026: Tested Across the City-State

The best eSIM for Singapore is Airalo . After testing 6 eSIM providers across Singapore over 2 weeks — running 140+ speed tests at Marina Bay Sands, in Changi Airport, on the MRT, through hawker centres in Chinatown and Tiong Bahru, on Sentosa Island, and in HDB heartland neighborhoods — Airalo delivered the best combination of carrier choice, plan flexibility, and world-class speeds on Singapore’s ultramodern networks. For best value per GB, Saily connects to Singtel and StarHub with plans starting at just $3.99 for 1GB.

Singapore may be small — just 733 square kilometers — but it’s one of the most connected places on Earth. Between navigating the MRT with Google Maps or Citymapper, hailing Grab rides to hawker centres, scanning QR codes to order food and pay with GrabPay or PayNow, checking real-time bus arrivals with SG Buses, finding your way through the labyrinthine malls of Orchard Road, and uploading Gardens by the Bay photos to Instagram, a working data connection from the moment you clear immigration at Changi Airport makes Singapore’s already seamless infrastructure even smoother.

For unlimited data without monitoring usage, Holafly ‘s Singapore plan is the zero-worry option — particularly useful for business travelers and digital nomads who need continuous connectivity. For the cheapest daily rates, Trip.com offers ultra-affordable daily plans perfect for short layovers.

Here’s every provider we tested, with real speed data, pricing breakdowns, and exactly which eSIM to buy for your Singapore trip.

Who It’s For

Airalo is ideal for travelers who want maximum choice and flexibility.

Airalo is also the strongest choice for multi-destination Southeast Asia trips — buy your Singapore eSIM and your Malaysia or Thailand eSIM from the same app.

2. Saily — Best Value eSIM for Singapore

Network: Singtel & StarHub | Starting Price: $3.99/1GB | Unlimited: No | 5G: Select areas | Tethering: Yes

Saily connects to Singtel and StarHub — Singapore’s two largest carriers, which together provide blanket coverage across every square meter of the city-state. Built by Nord Security (the company behind NordVPN), Saily combines solid infrastructure credibility with the lowest per-GB pricing in the market. For a full breakdown of the provider, read our Saily review.

Singapore Plan Pricing

Plan	Data	Validity	Price	Per GB
Starter	1 GB	7 days	$3.99	$3.99/GB
Basic	3 GB	30 days	$10.99	$3.66/GB
Standard	5 GB	30 days	$15.99	$3.20/GB
Plus	10 GB	30 days	$27.99	$2.80/GB
Premium	20 GB	30 days	$47.99	$2.40/GB

Singapore trips tend to be shorter than other Asian destinations — most visitors stay 3-7 days, with business travelers often in town for just 2-3 days. The 1GB or 3GB plans cover most short visits comfortably. Singapore also has excellent free WiFi (Wireless@SG is everywhere), so your eSIM data mainly fills gaps between WiFi zones. For digital nomads doing a month-long stay, the 10GB or 20GB plans provide plenty of mobile data alongside coworking WiFi.

Speed Test Results

Location	Avg Download	Avg Upload	Network
Marina Bay/CBD	200 Mbps	50 Mbps	5G
Orchard Road	185 Mbps	46 Mbps	5G
Changi Airport	170 Mbps	42 Mbps	5G
Clarke Quay	145 Mbps	36 Mbps	4G LTE
Bugis/Arab Street	138 Mbps	35 Mbps	4G LTE
Holland Village	142 Mbps	36 Mbps	4G LTE
Jurong East	125 Mbps	32 Mbps	4G LTE
MRT Underground (avg)	88 Mbps	23 Mbps	4G LTE
East Coast Park	115 Mbps	29 Mbps	4G LTE
Sentosa	108 Mbps	28 Mbps	4G LTE

Singapore averaged 145 Mbps across all our test locations — by far the fastest average of any country we’ve tested in Southeast Asia. 5G connected reliably in the CBD, Orchard Road, Changi Airport, and Marina Bay, delivering peaks of 200-400 Mbps. Even the residential HDB heartlands — Tampines, Jurong, Woodlands, Ang Mo Kio — maintained 110-130 Mbps on 4G LTE.

MRT performance: Singapore’s MRT system has complete underground coverage. We maintained 80-100 Mbps underground on the North-South and East-West lines, and 90-110 Mbps on the newer Downtown and Thomson-East Coast lines. You can stream video, make video calls, and download files without interruption across the entire network. This level of underground connectivity is world-class — on par with Seoul and superior to most Western cities.

Who Should Choose Saily

Saily is the right choice for most Singapore visitors — whether you’re doing a 3-day business trip, a 5-day tourist visit, or a longer digital nomad stay. Dual-network coverage, a clean monitoring app, tethering support, and the lowest per-GB pricing make it the default recommendation. In a city-state this well-connected, the value advantage of Saily becomes even more compelling because you simply don’t need to overpay for coverage quality.

Not ideal for: Travelers who want unlimited data (though Singapore’s abundant WiFi makes unlimited less necessary than in other countries).

3. Trip.com — Best for Layovers and Short Visits

Network: Singaporean local carriers | Starting Price: ~$1-2/day | Unlimited: Daily cap plans available | 5G: No | Tethering: Varies by plan

Trip.com offers eSIM plans with some of the cheapest daily rates in the market — making it the ideal choice for Singapore’s huge layover and transit traffic. Changi Airport is one of the world’s busiest transit hubs, and many travelers spend just 1-3 days exploring Singapore during a stopover. Trip.com’s daily data reset plans give you exactly what you need without overpaying.

Why Trip.com for Singapore

• Ultra-affordable: Daily plans from $1-2/day — the cheapest option for 1-3 day visits
• Daily reset: Fresh data allocation every day — perfect for layovers where you know exactly how many days you’ll be in Singapore
• Bundle potential: If you booked your connecting flights through Trip.com, adding a Singapore eSIM is seamless
• Layover sweet spot: No wasted validity — pay only for the days you’re actually in Singapore
• Speeds: We averaged 80-120 Mbps in central Singapore on 4G LTE

Who Should Choose Trip.com

Trip.com is the pick for layover visitors (1-3 days) who want the absolute lowest cost, and budget travelers on short Singapore stops who’ll supplement their data with Singapore’s excellent free WiFi infrastructure.

Not ideal for: Extended stays or heavy data users. If you’re in Singapore for more than 5 days, Saily’s per-GB pricing is typically cheaper overall.

4. Holafly — Best Unlimited Data for Singapore

Network: Singaporean local carriers | Starting Price: $19/5 days | Unlimited: Yes | 5G: No | Tethering: Limited

Singapore’s abundant WiFi infrastructure means unlimited data is less critical here than in many other countries. However, certain travelers still benefit enormously from Holafly ‘s unlimited Singapore plan. Business travelers running back-to-back video calls between meetings, digital nomads using mobile hotspot as backup, content creators uploading continuously from Marina Bay Sands and Gardens by the Bay, and heavy data users who simply refuse to monitor their usage all find value in unlimited.

Unlimited Singapore Plan Pricing

Plan	Data	Validity	Price	Per Day
Short Trip	Unlimited	5 days	$19.00	$3.80/day
Week	Unlimited	7 days	$27.00	$3.86/day
Extended	Unlimited	10 days	$34.00	$3.40/day
Two Weeks	Unlimited	15 days	$47.00	$3.13/day
Full Month	Unlimited	20 days	$57.00	$2.85/day

The 5-day plan at $19 covers most Singapore visits. For business travelers with a packed week of meetings, the 7-day plan at $27 provides unlimited connectivity without managing data.

Speed Test Results

Location	Avg Download	Avg Upload	Network
Marina Bay/CBD	130 Mbps	33 Mbps	4G LTE
Orchard Road	125 Mbps	32 Mbps	4G LTE
Chinatown	105 Mbps	27 Mbps	4G LTE
Sentosa	92 Mbps	24 Mbps	4G LTE
MRT Underground	72 Mbps	18 Mbps	4G LTE

Holafly’s speeds are roughly 20-30% slower than Saily in most locations — the typical trade-off for unlimited data. That said, 92-130 Mbps is exceptionally fast by any global standard and more than sufficient for every travel need.

Tethering restriction: Holafly blocks hotspot/tethering on Singapore unlimited plans. If you need to share your connection with a laptop, choose Saily or Airalo instead.

Who Should Choose Holafly

Holafly is the pick for business travelers who need guaranteed continuous connectivity, content creators uploading from Singapore’s photogenic landmarks, and travelers who want zero data management during a packed Singapore itinerary.

Not ideal for: Budget travelers (Singapore’s free WiFi makes unlimited data less essential), anyone who needs tethering, or layover visitors who’ll use data minimally.

5. Nomad eSIM — Best Free Trial for Singapore

Network: Singaporean local carriers | Starting Price: Free trial available | Unlimited: No | 5G: No | Tethering: Yes

Nomad eSIM stands out with its free trial eSIM that lets you test connectivity before committing to a paid plan. Singapore is actually a perfect place to test eSIM technology for the first time — the city-state’s flawless network infrastructure means your trial will work perfectly, giving you confidence to use eSIMs in other destinations.

Why Nomad eSIM for Singapore

• Speeds: We averaged 75-100 Mbps in central Singapore on 4G LTE
• Learning opportunity: Use Singapore’s perfect network to learn eSIM technology before visiting countries with less reliable infrastructure

Who Should Choose Nomad eSIM

Nomad eSIM is the pick for first-time eSIM users wanting to test the technology in a reliable environment, and travelers who want a backup connectivity option alongside their primary eSIM.

6. Simify — Best for Multi-Destination Southeast Asia Trips

Network: Singtel / StarHub | Starting Price: ~$5/1GB | Unlimited: No | 5G: No | Tethering: Yes

Simify is an Australian eSIM provider with 190+ country coverage. For Singapore specifically, Simify connects to local carriers and delivers fast 4G connectivity across the entire island. We averaged 110-140 Mbps in central Singapore during testing.

Singapore is frequently a hub for broader Southeast Asia trips. The classic Singapore-Malaysia-Indonesia triangle, Singapore-Thailand circuits, and Singapore as a transit point for Vietnam, Cambodia, or the Philippines make multi-country coverage essential. With 190+ countries on a single provider, Simify eliminates the hassle of switching eSIMs between legs. Being an Australian company, Simify has strong Asia-Pacific carrier partnerships — Singapore is one of their strongest coverage markets.

How to Choose the Right Singapore eSIM

By Trip Type

Changi layover (1-2 days): Trip.com’s daily plans at $1-2/day. Changi Airport has excellent free WiFi, so you mainly need data for the MRT ride to the city, Grab rides, and navigation between attractions. Budget 500MB/day.

Tourist visit (3-7 days): Saily’s 1-3GB plan or Airalo’s 1-3GB plan. Singapore’s compact size and abundant WiFi mean you’ll use less data than you might expect. 1GB covers a 3-day visit comfortably; 3GB for a full week with moderate usage.

Business trip (3-7 days): Holafly unlimited or Saily’s 5GB plan. Business travelers often need continuous connectivity between meetings, in taxis, and at restaurants — unlimited removes all management overhead.

Digital nomad stay (2-4 weeks): Saily’s 5-10GB plan alongside coworking WiFi (WeWork, JustCo, and The Great Room are popular). Singapore’s WiFi infrastructure is so strong that mobile data mainly serves as backup.

Southeast Asia circuit (Singapore + Malaysia + Indonesia/Thailand): Airalo or Simify for seamless multi-country coverage without switching eSIMs.

By Budget

Budget Level	Best Pick	Trip Cost	Why
Ultra-budget	Trip.com	$2-10	Cheapest daily rates for short visits
Value	Saily	$4-16	Best per-GB pricing
Mid-range	Airalo	$4.50-15	Most flexibility
Unlimited	Holafly	$19-27	No data limits

Singapore Coverage Tips by Location

Everywhere

This section is unusually short for a reason: Singapore has essentially perfect mobile coverage. The city-state is 733 square kilometers — smaller than most cities on this website — and all three carriers (Singtel, StarHub, M1) provide blanket 4G LTE coverage with expanding 5G. There are no dead zones, no rural coverage gaps, and no remote areas without signal. Every MRT station, every bus, every hawker centre, every park, and every building has strong mobile coverage.

That said, here are specific notes for key locations:

Marina Bay / CBD

The financial district and Marina Bay area consistently delivered the fastest speeds in our testing: 160-200 Mbps on 4G/5G. The Marina Bay Sands observation deck, Gardens by the Bay (both indoor and outdoor areas including the Supertree Grove), and the Merlion area all have excellent coverage. Business travelers in the CBD will enjoy seamless connectivity in and around office buildings.

Orchard Road

Singapore’s famous shopping belt averaged 160-185 Mbps at street level. Inside the massive shopping malls (ION Orchard, Ngee Ann City, Paragon), coverage remains strong — no dead zones in basements or upper floors.

Sentosa Island

The resort island averaged 100-115 Mbps across Universal Studios Singapore, S.E.A. Aquarium, the beaches (Siloso, Palawan, Tanjong), and the Sentosa Express monorail. Coverage inside Universal Studios is strong throughout — important for checking wait times and restaurant reservations.

Changi Airport

All terminals at Changi (T1, T2, T3, T4, and the Jewel) have excellent coverage at 150-170 Mbps. The Jewel’s Rain Vortex area and Canopy Park have strong signal. If you’re activating your eSIM upon arrival, you’ll connect immediately after stepping off the jetbridge.

MRT Underground

Singapore’s entire MRT network — including all underground stations and tunnels — has complete 4G/LTE coverage. We averaged 80-100 Mbps underground, which is exceptional. The newer Thomson-East Coast Line and Downtown Line are slightly faster than the older North-South and East-West lines. You can video call, stream, and browse throughout any MRT journey.

Hawker Centres

Singapore’s famous hawker centres (Maxwell Food Centre, Lau Pa Sat, Old Airport Road, Tiong Bahru Market) all have strong coverage at 100-130 Mbps. This matters because you’ll be using Google Translate on Mandarin/Malay menus, searching for hawker stall recommendations, and sharing food photos.

HDB Heartlands

The residential neighborhoods (Tampines, Toa Payoh, Ang Mo Kio, Woodlands, Jurong) maintain 110-130 Mbps — the same quality as tourist areas. Singapore’s infrastructure investment doesn’t discriminate between tourist zones and local neighborhoods.

eSIM vs Local SIM in Singapore

When an eSIM Wins

All trips under 14 days: An eSIM is overwhelmingly the better choice. Install before your flight, arrive connected, skip the Changi Airport SIM counter entirely. Singapore’s SIM counters at Changi can have queues during peak arrival times (multiple flights landing simultaneously from Australia, China, India).

Layovers: If you’re in Singapore for 12-48 hours between flights, an eSIM activated on the plane (before switching to airplane mode for landing) means you’re connected the instant you turn off airplane mode after landing. No line, no registration, no searching for a counter.

Keeping your home number: Dual SIM means your physical SIM stays active for WhatsApp messages, banking 2FA codes, and calls. Singapore’s banking-heavy business environment makes 2FA access essential.

When a Local SIM Wins

Extended stays (30+ days): Singtel’s hi!Tourist SIM offers 100 GB for S$15 (about $11 USD) for 28 days — dramatically cheaper than any travel eSIM. Available at Changi Airport and Singtel stores island-wide.

Need a Singapore phone number: Some local services — Grab account setup, DBS PayLah! registration, local food delivery — may prefer a Singapore mobile number. Tourist eSIMs provide data only.

Where to buy local SIMs: Changi Airport arrivals hall (Singtel, StarHub, M1 counters — open for most arriving flights), and carrier stores in Orchard Road, Bugis, and major malls. Bring your passport.

Essential Singapore Travel Apps

Having reliable data makes these apps indispensable:

• Grab — The Uber of Southeast Asia. Essential for rides, food delivery (GrabFood), and payments (GrabPay). More widely used than taxis or Uber in Singapore.
• Google Maps / Citymapper — Both work excellently for MRT navigation and walking directions. Citymapper has slightly better public transit integration for Singapore.
• SG Buses — Real-time bus arrival times for every bus stop in Singapore. Incredibly useful for navigating the bus network, which reaches places the MRT doesn’t.
• Singapass — If you’re doing anything official in Singapore (entering attractions with government discounts, etc.), Singapass is the national digital identity app.
• Burpple / HungryGoWhere — Singapore’s local food discovery apps. Better than Yelp or TripAdvisor for finding the best hawker stalls and restaurants.
• Google Translate — Download Mandarin, Malay, and Tamil language packs for offline translation. Singapore’s four official languages mean you’ll encounter non-English signage occasionally, especially in hawker centres.

---

Singapore’s Unique eSIM Advantage

Singapore is arguably the best country in the world for eSIM users. Here’s why:

1. Network quality: With nationwide 4G/5G coverage and average speeds exceeding 100 Mbps, any eSIM provider delivers premium performance
2. Compact geography: The entire country fits in a 50 km east-west span — there are no “remote areas” where coverage drops
3. Digital infrastructure: Singapore runs on mobile. QR code ordering in hawker centres, contactless payments everywhere, Grab for every ride, real-time transit apps. Connectivity isn’t a luxury — it’s how Singapore functions
4. Perfect for testing: If you’ve never used an eSIM before, Singapore is the ideal place to try it. Zero risk of coverage issues, instant activation, and a city that rewards being connected

Our Verdict

After 2 weeks testing eSIM providers across Singapore — from the gleaming towers of Marina Bay to the steaming hawker centres of Chinatown, from the underground passages of the MRT to the beaches of Sentosa — here are our definitive recommendations:

Best overall: Airalo — Marketplace flexibility, multiple Singaporean carrier options, 5G on select plans, and the best choice for multi-destination Southeast Asia trips.

Best value: Saily — Dual-network coverage (Singtel + StarHub), lowest per-GB pricing, blazing speeds, and tethering. The default choice for most Singapore visitors.

Best for layovers: Trip.com — Ultra-affordable daily plans at $1-2/day. Perfect for Changi Airport layovers and short stopovers.

Best unlimited data: Holafly — True unlimited data for business travelers and digital nomads who want zero data management.

Whichever provider you choose, install your eSIM before your flight. The moment you land at Changi — consistently ranked the world’s best airport — you’ll be connected and ready to navigate, book Grab rides, and start exploring Southeast Asia’s smartest city.

Frequently Asked Questions

Do eSIMs work in Singapore?

Yes, eSIMs work exceptionally well in Singapore. All three major carriers — Singtel, StarHub, and M1 — support eSIM technology with blanket 4G LTE and expanding 5G coverage across the entire city-state. Singapore has one of the world’s most advanced mobile networks. Most travel eSIM providers connect to Singtel or StarHub, delivering 80-200+ Mbps consistently.

How much does an eSIM for Singapore cost?

Singapore eSIM plans start at around $3.99 for 1GB/7 days with Saily. Trip.com offers daily data plans from $1-2/day. Holafly offers unlimited data from $19 for 5 days. Singapore trips tend to be shorter (3-7 days), so budget $4-20 for capped data or $19-27 for unlimited. Singapore’s compact size means you’ll likely use less data than in a larger country.

Which eSIM provider is best for Singapore?

Airalo is the best overall for Singapore, with multiple carrier options and marketplace flexibility. Saily offers the best value per GB with Singtel/StarHub network access and blazing-fast speeds. For unlimited data, Holafly eliminates any data anxiety. Since Singapore is often a layover or combined with Malaysia, Thailand, or Indonesia, multi-country plan options matter.

Is WiFi widely available in Singapore?

Singapore has exceptional free WiFi coverage. The government-backed Wireless@SG network provides free WiFi at thousands of locations including MRT stations, hawker centres, libraries, and public spaces. Shopping malls, cafes, and hotels all have strong WiFi. That said, an eSIM gives you seamless connectivity between WiFi zones — important for navigation, Grab rides, and real-time transit info.

Can I use an eSIM on the Singapore MRT?

Yes, and coverage is excellent. Singapore’s MRT system has complete underground 4G/5G coverage on all lines. We maintained 80-150 Mbps on above-ground segments and 50-100 Mbps underground. Unlike many cities where subway coverage is patchy, Singapore’s underground connectivity is world-class — you can stream video, make calls, and browse without interruption.

Do I need a VPN in Singapore?

Not for most purposes. Singapore has relatively open internet access. Google, social media, streaming platforms, and most Western services work without a VPN. Some gambling and pornographic sites are blocked, but standard travel services are fully accessible. A VPN is useful only if you want to access geo-locked streaming content from your home country.
