Best eSIM for Singapore 2026: 15 Providers Compared

In Singapore, Singtel, StarHub, M1 and SIMBA cover the whole island on 4G and 5G, MRT tunnels and high-rise interiors included, so the choice comes down to price and plan length. SingTel took the top overall position in nPerf's 2026 barometer (nPerf, 2026), and Singtel's standalone 5G passed 95% nationwide coverage in 2022 (Singtel, 2022). That makes Singapore one of the easiest countries in the world to stay connected in — and a travel eSIM is the fastest way to get online the moment you clear customs at Changi Airport. With the best eSIM for Singapore, you skip the SIM card counters entirely: purchase before your flight, scan a QR code, and you have mobile data before you reach baggage claim.

Singtel, StarHub, M1 and SIMBA in nPerf's 2026 barometer

Singapore's four networks are fast by any standard. The nPerf 2026 barometer for Singapore, measured from April 2025 to March 2026, ranks Singtel first with 106,722 nPoints and a download speed of 275.68 Mbps. StarHub is second at 200.24 Mbps and M1 third at 186.67 Mbps, with the lowest latency of the four at 22.26 ms. SIMBA, the former TPG network, comes fourth at 33.2 Mbps.

In practice, all four cover the whole island, including MRT tunnels, Changi's terminals and the interiors of malls and office towers, so a visitor rarely notices the difference. If you plan heavy video calls or uploads, a plan on Singtel, StarHub or M1 gives you the most headroom. Each Simsima plan for Singapore names its network in the plan details.

Singtel's tourist SIM and the passport check at Changi

Singapore's operators sell prepaid SIMs for visitors at Changi Airport, registered with your passport. Singtel's hi!Tourist offer (checked October 2026) starts at S$10 for 7 days with a large 5G data allowance that also works in Malaysia, Indonesia, Thailand and Hong Kong, plus local calls and SMS, and it is available as an eSIM too. Longer 30-day versions add roaming in more countries.

Those local offers are strong value and come with a Singapore number. A travel eSIM bought before you leave saves the counter visit and is working when you land, and it can be part of a regional plan if Singapore is one stop among several. Compare the tables above with the local offers for your dates.

Before you land: the SG Arrival Card

Every traveler entering Singapore, apart from some transit passengers, must submit the SG Arrival Card with an electronic health declaration. According to the Immigration and Checkpoints Authority, it is free and must be done within three days before arrival, including the arrival day, on the ICA website or in the MyICA app. Do it at home, or on Wi-Fi before boarding, at the same time as you install your eSIM; avoid paid third-party sites that charge for the same form.

Do you need data in Singapore with so much free Wi-Fi?

Free Wi-Fi is everywhere in Singapore: across Changi Airport, in malls such as ION Orchard, VivoCity and Jewel, in many hawker centers, and through the government-backed Wireless@SG network at thousands of public hotspots. On a short layover spent at Changi, airport Wi-Fi is enough.

Data earns its keep once you move around: Google Maps walking directions between Chinatown and Tiong Bahru, booking a Grab when an afternoon storm hits, or checking Gardens by the Bay's opening times from the street. A private connection is also safer than public Wi-Fi for banking apps.

Three days in Singapore: data for a city stopover

A typical three-day stopover covers Marina Bay and Gardens by the Bay, Chinatown and Little India's hawker centers, Sentosa or the Singapore Zoo, and an evening on Orchard Road. The MRT and buses accept contactless bank cards through SimplyGo, so you don't need a transport app, and Grab, Gojek and TADA handle rides. Data goes on maps, ride-hailing, restaurant searches and photos.

Expect 300 to 600 MB a day, or 1 to 2 GB for three days, since you are often on Wi-Fi. A small capped plan from the table above covers it. Long stays and heavy streamers are better served by an unlimited plan.

Where a travel eSIM falls short in Singapore

• No Singapore number: some local services and loyalty apps verify you by SMS to a Singapore number
• Local tourist SIMs at Changi can include more data for the money; a travel eSIM trades that for convenience
• Sharing data with a laptop or a second phone in Marina Bay depends on the plan's hotspot terms
• Make sure your phone supports eSIM and is unlocked before the flight to Changi

What Does the Best eSIM for Singapore Cost?

Singapore eSIM pricing splits into two distinct categories: unlimited data plans (sold by duration) and capped plans (sold by total data allowance). Below are two comparison tables covering both types, with prices verified as of 2026-10-17. All prices are in USD.

Unlimited Data Plans

Unlimited plans are ideal if you stream video or simply prefer not to monitor your data usage. Prices vary significantly across providers for the same duration.

Capped Data Plans

Capped plans work well for travelers who mainly use maps, messaging apps, and light social media browsing. They cost less than unlimited options and are a good match for Singapore, where free Wi-Fi supplements your mobile data at most indoor locations.

Simsima provides instant digital delivery with no registration or ID verification required — you receive your eSIM QR code immediately after purchase. For travelers heading to multiple countries, Simsima’s multi-country Trip Packs cover several Southeast Asian destinations under a single eSIM profile, which eliminates the need to buy separate plans for each stop.

How to Get Your eSIM Ready for Singapore

Setting up a travel eSIM takes a few minutes. Complete these steps before your flight so you have data the moment you land at Changi. Most providers, including Simsima, deliver the QR code instantly via email, so you can set everything up the night before departure.

1. Confirm your phone supports eSIM. Compatible devices include iPhone XS and later, Samsung Galaxy S20 and later, Google Pixel 3 and later, and most recent flagship Android phones. Check the full list on the supported devices page.
2. Purchase your Singapore eSIM plan online. Choose between unlimited data (if you want worry-free usage) or a capped plan (if you prefer a lower price and will rely on Wi-Fi for heavy tasks).
3. Scan the QR code you receive via email. On iPhone, go to Settings > Cellular > Add eSIM. On Android, go to Settings > Network & Internet > SIMs > Add eSIM. Follow the on-screen prompts to install the profile.
4. Label the new eSIM line (for example, ‘Singapore Travel’) so you can distinguish it from your home SIM in your phone’s settings.
5. When you land in Singapore, enable data roaming on your eSIM line and disable cellular data on your home SIM. This prevents accidental roaming charges from your primary carrier while routing all data through your travel eSIM.

If you run into issues during installation, contact Simsima support, which usually replies within 24 hours. The most common fix is to ensure your phone’s software is up to date and that your device is connected to Wi-Fi while scanning the QR code.

Changi as a hub: Johor Bahru, Batam and onward flights

Singapore is a starting point for many Southeast Asia trips. Overland, the Woodlands Causeway and the Second Link lead to Johor Bahru in Malaysia; by ferry, Batam and Bintan in Indonesia are about an hour away; and Changi has direct flights to Bangkok, Kuala Lumpur, Bali, Ho Chi Minh City and Manila. A Singapore plan stops working at the border.

If Singapore is one stop among several, a regional plan that covers all your countries saves installing a new eSIM at each border. For a trip spent entirely in Singapore, a single-country plan is the simpler choice.
