Notes
RecommendedRoamix eSIM
Most travellers
Instant activation on a world-class 5G network, works everywhere from MRT tunnels to hawker centre back lanes.
Local physical SIM
Longer stays needing a local number
Available at Changi arrivals and convenience stores. Requires a SIM swap that takes your home number offline.
Pocket wifi
Groups sharing one device
Singapore's strong public wifi reduces the need, but pocket wifi avoids SIM swapping for multi-device groups.
Carrier roaming
Very short layovers
The priciest option, typically charged per megabyte or per day by home carriers.
For most Singapore visitors, a Roamix eSIM is the simplest approach. The 5G network is extraordinary and the city's compactness means even a small data plan covers a full week comfortably.

Get your Singapore eSIMMobile Networks in Singapore
Singapore has arguably the most complete mobile network in the world, with three operators all exceeding 99% outdoor 5G standalone coverage. Speed and reliability are excellent everywhere, from the Orchard Road shopping belt to Sentosa Island and through every MRT tunnel. A Roamix Singapore eSIM gives you instant access to this network from the moment you arrive at Changi.
Leads for 5G coverage experience and overall download speed, with the first commercial 5G+ (5G-Advanced) service in Singapore. Largest operator by market share.
Leads for download speed experience in independent tests and has the strongest 5G upload speeds. Excellent across the CBD, Orchard Road and Changi.
Leads for 5G availability and 5G download speed in Opensignal testing. Strong competitive option, jointly deploying infrastructure with StarHub.
Typical Speeds
Expect 100 to 420 Mbps on 5G across the city. Singtel leads on median overall download speed at around 297 Mbps.
5G Status
All three major operators (Singtel, StarHub and M1) achieved over 99% outdoor 5G standalone population coverage by early 2024.
Singapore is so well covered that your data plan size matters more than which specific network you are on. All three operators deliver fast, reliable data everywhere you are likely to go.
Coverage is essentially complete across the island. Even some offshore islands connected by ferry have reasonable signal. The only genuine dead zones are on open-water ferry routes between Singapore and Indonesian islands.
Singapore networks use globally standard 3.5 GHz 5G NR and LTE bands supported by virtually every recent unlocked smartphone.
Data Usage Guide
Singapore trips lean on transit routing, food discovery and social sharing more than heavy streaming or video calls. The city is small and efficient, so data needs are moderate compared to larger countries.
Use the Transit or Citymapper app for live MRT routing rather than Google Maps transit view, as it handles Singapore's complex interchange connections better.

Get connected the moment you land in Singapore.
Get your Singapore eSIMArrival Checklist
Confirm your Roamix eSIM is connected before leaving the arrival hall, since Changi's layout means you move quickly from the gate.
If you have a Singapore EZ-Link or NETS FlashPay card from a previous trip, top it up. If not, buy one at a transit counter for MRT and bus travel.
Download the Transit app or Citymapper for live MRT route planning before you enter the underground network.
Singapore is cashless, but having 20 to 30 SGD is useful for some hawker centre stalls and wet markets.
Note that the MRT runs on a schedule with last trains from midnight to 12:30 AM, so plan late nights around Grab or taxi.
How locals communicate
WhatsApp is the dominant messaging app in Singapore for both personal and business communication. Telegram is also widely used. SMS is largely replaced by app messaging.
Keep your home SIM active for two-factor authentication codes while using the Roamix eSIM for data.
Airports in Singapore
Singapore Changi Airport Terminal 1
Singapore
Free unlimited high-speed wifi throughout Terminal 1 and the Jewel Changi transit hub. Consistently rated among the world's best airport wifi.
Install your Roamix Singapore eSIM before departure so it connects at landing. Terminal 1 is linked directly to Jewel Changi and the underground MRT link to the city, so a connected phone lets you navigate both without delay.
Singapore Changi Airport Terminal 2 and 3
Singapore
Free unlimited high-speed wifi throughout Terminals 2 and 3. The MRT Changi Airport station in the basement of these terminals has full 5G coverage.
The MRT train to the city departs from the basement of Terminal 2 and 3. A Roamix eSIM connected at landing gives you real-time train times and Grab booking before you exit the terminal.
Singapore Changi Airport Terminal 4
Singapore
Free high-speed wifi throughout Terminal 4, which serves budget and regional carriers. No direct MRT link, so wifi and mobile data are important for organising ground transport.
Terminal 4 does not connect to the MRT. Use your Roamix eSIM to book a Grab from the terminal's designated ride-hailing pick-up area immediately on arrival to avoid queues at the metered taxi stand.
Seletar Airport
Singapore
Smaller general aviation airport with limited commercial passenger services and basic wifi.
Primarily used for private aviation and regional turboprop services. A Roamix eSIM keeps you connected for onward ground transport from this less-served terminal.
Visa & Entry for Singapore
Singapore offers visa-free entry to nationals of over 160 countries, including the entire EU, US, UK, Australia, Canada, Japan and most of Southeast Asia. Stays of 30 to 90 days are granted on arrival with no advance application.
eVisa / ETA
Most nationalities simply enter without any visa. There is no ETA or advance online registration required for eligible passport holders. Check the ICA Singapore website if you are unsure of your status.
Passport validity
Your passport should be valid for at least 6 months beyond your intended departure date from Singapore.
Onward ticket
Proof of onward travel and sufficient funds may be requested at immigration, though this is rarely enforced for most Western passport holders.

Entry rules change. Confirm current requirements with the Singapore Immigration and Checkpoints Authority before booking.
Get connected the moment you land in Singapore.
Get your Singapore eSIMMoney & Payments in Singapore
Singapore is highly cashless. Contactless payment works at hawker centres, taxis, bus top-ups and virtually everywhere else. A connected phone wallet is your most useful financial tool.
Cash vs Card
Cards and contactless are accepted almost universally. Some older hawker stalls and traditional wet markets are cash only. Keep 20 to 30 SGD for these situations.
ATMs
ATMs are widely available in malls and MRT stations. Always choose to be charged in SGD to avoid dynamic conversion fees.
Payment Apps
PayNow is the dominant local instant payment system. Apple Pay and Google Pay are accepted everywhere. A connected Roamix eSIM keeps your payment apps active throughout your stay.
Daily Budget
Budget travellers spend 60 to 100 SGD a day. Mid-range travellers spend 150 to 300 SGD. Singapore is one of Asia's most expensive cities, though hawker food keeps meals cheap.
Data cost: Carrier roaming in Singapore can exceed 15 SGD a day, while a Roamix plan typically covers a full week for a fraction of that cost.
Getting Around Singapore
Singapore's public transport is among the best in the world. The MRT covers the whole island and integrates with buses and the LRT. All transport is app and contactless card accessible.
MRT and buses
Signal extends into every MRT tunnel across all lines. Use an EZ-Link card or contactless bank card to tap in, and a transit app for live departure times and route planning.
Grab
The dominant rideshare platform in Singapore, requiring an active data connection to book. Gives fixed prices and is faster than flagging a taxi at peak times.
Walking and cycling
Singapore is compact and walkable in many areas. Park connector cycling paths and bike-share schemes use connected apps to unlock and return bikes.
Sentosa cable car and ferry
Good signal on the Sentosa cable car. Ferry routes to Indonesian islands (Bintan, Batam) cross out of Singapore coverage territory partway through.
Regions & Travel
Singapore is a compact, incredibly efficient city-state that rewards exploration. The MRT reaches almost everywhere, street food is world class and the cultural diversity across Chinatown, Little India and Kampong Glam packs variety into short distances. A connected phone makes transit seamless and helps find the best hawker stalls.

Frequently Asked Questions
Singapore eSIM, connectivity, and travel
What is the best eSIM for Singapore?
Roamix is a top choice for Singapore because it connects to one of the world's best 5G networks and activates automatically at Changi Airport. You install it before you fly and land with local data speed from the gate.
Do I need a SIM card for Singapore?
You do not need a physical SIM. A Roamix Singapore eSIM gives you local 5G data without swapping cards, activates on arrival at Changi and avoids both the SIM counter and expensive carrier roaming.
What is the most affordable eSIM for Singapore?
Roamix offers Singapore data plans that significantly undercut carrier roaming rates. Given Singapore's compact size, even a 4 to 6 GB plan covers most visits comfortably.
Does an eSIM work on the Singapore MRT underground?
Yes. Singapore's networks provide excellent coverage through every MRT tunnel on all lines. A Roamix eSIM works for navigation, messaging and music streaming throughout your underground journeys.
How do I set up a Roamix eSIM for Singapore?
Buy your plan on the Roamix Singapore eSIM page, install over wifi before departure, then enable data roaming on the Roamix line. It connects automatically to Singtel, StarHub or M1 on landing with no SIM counter needed.
Can I use WhatsApp, FaceTime and Google in Singapore?
Yes. Singapore has a fully open internet with no app restrictions. WhatsApp, FaceTime, Google and all social media work normally on a Roamix eSIM without a VPN.
How much data do I need for a week in Singapore?
Most visitors use 4 to 6 GB for a one-week trip covering MRT navigation, Grab, food browsing and photo sharing. Choose 10 GB or more if you tether a laptop or make frequent video calls.
Do I need a visa to visit Singapore?
Nationals of over 160 countries enter Singapore visa free for 30 to 90 days with no advance application. Simply land at Changi and clear immigration with your passport. Check the ICA Singapore website if you are unsure of your eligibility.
Do I still need cash in Singapore?
Singapore is highly cashless. However, keep 20 to 30 SGD for a handful of traditional hawker stalls and wet markets that do not accept cards. A connected Roamix eSIM keeps your banking app and payment wallets running throughout your stay.
What is the best connectivity option for a Singapore stopover?
For a stopover of one to three days, a Roamix eSIM on a small 2 to 4 GB plan is the ideal option. You get instant 5G from Changi without a SIM swap, and the plan size is enough for transit routing, Grab and social media.
Is my phone compatible with a Singapore eSIM?
Most recent phones support eSIM including iPhone XS and newer, Google Pixel 3 and newer, and Samsung Galaxy S20 and newer. Your phone must be carrier unlocked to use a Roamix eSIM.
Is Changi Airport wifi good enough or should I get a Singapore eSIM?
Changi wifi is excellent and free throughout the airport, but it ends when you leave the terminal. A Roamix eSIM connects at landing and stays with you on the MRT, in the taxi and everywhere else, which is far more useful for a full trip.
Will my Roamix eSIM work at the MacRitchie Reservoir Treetop Walk?
Yes, with the caveat that the Treetop Walk suspension bridge section can drop to 3G in dense canopy. Coverage is strong at the main car park and along the main path. Download an offline trail map at home before you enter the reserve, and use Roamix data to book your free timed entry slot on the NParks website in advance.
Does my Roamix eSIM work at Jewel Changi Airport and on Sentosa Island?
Yes. Jewel Changi Airport has full Singtel 5G across all five levels including Canopy Park, and Sentosa Island has complete 5G coverage at Universal Studios Singapore, Siloso Beach, Palawan Beach and throughout the Resorts World complex. Use Roamix data to pre-book Canopy Park experiences at Jewel and ticket queues at Universal Studios, both of which sell out on weekends.
