Singapore eSIM

Singapore's networks are among the easiest anywhere for a visitor: a travel eSIM picks up Singtel or M1 the moment you land at Changi, and signal follows you into the MRT tunnels. The places where phones trip up are the borders, the Causeway to Johor Bahru and the ferries to Batam and Bintan, which a Singapore plan doesn't cover.

What a week of data costs in Singapore

Prices for 7 days of data, checked on 2 November 2026. Daily passes charge for each day you use the phone abroad, per phone.

For a family of four on Verizon, that's $336 for one week. Singapore's own tourist SIMs are cheap for the data you get, and StarHub and M1 sell 30-day versions from S$12. What you pay for with an eSIM is skipping the counter and the passport check, and keeping your home number in the phone.

Landing at Changi (SIN)

Almost every visitor arrives at Changi, which has four terminals. Switch the kimsim line on as the plane taxis in, so you can message your hotel or book a ride while you walk to immigration.

At Changi, in order: turn on Data Roaming for the kimsim line only, then head to immigration. Many visitors are directed to automated lanes, and first-timers have their face, iris and fingerprints enrolled there. Your passport isn't stamped; the visit pass arrives as an e-Pass by email, so it helps to be online.

SIM counters and Wi-Fi: Changi says prepaid SIMs are sold at Changi Recommends booths and money changers in every terminal. StarHub's counters are in the arrival halls of Terminals 1 to 4. With your eSIM working, you can walk past them. If you need a fallback, #WiFi@Changi covers public and transit areas with no registration.

Into the city: the MRT leaves from Changi Airport station; change at Tanah Merah for the East West Line or at Expo for the Downtown Line. The first train is at 5:31am (5:59am on Sundays and public holidays). A taxi from the ranks in arrivals takes about 30 minutes and costs S$25 to S$45 on the meter, plus an airport surcharge. Grab, Gojek, Zig, TADA and Ryde pick up at the signed Arrival and Ride-Hailing pick-up points.

Networks and coverage

Singapore has four mobile operators: Singtel, StarHub, M1 and SIMBA, which was called TPG Singapore until April 2022 and launched commercially in March 2020. A planned sale of M1 to SIMBA, announced in August 2025, fell through in 2026, so M1 still runs as its own network. Your phone shows the Singapore operator's name, not kimsim.

Coverage is generally strong across the main island, and underground too. Singtel said in September 2024 that it had 5G across all six MRT lines, including every Thomson-East Coast Line station then open. That's the operator's own claim; we haven't tested it.

Where it gets fiddly is the edges. StarHub warns that in border areas such as the Causeway and Tuas, phones can latch on to stronger Malaysian signals, and that the coast can do the same. If data stops in Woodlands or Tuas, choose a Singapore network by hand. Expect weaker signal on Pulau Ubin and the Southern Islands. The networks your plan uses are listed above.

Area by area

• Marina Bay and the Civic District: busy and well covered. Signal is fine for photos and video calls from the waterfront.
• Sentosa: the Sentosa Express monorail starts at VivoCity, above HarbourFront MRT station. The island is close to the mainland, but busy beaches and attraction queues can slow data at peak times.
• Jewel Changi: the mall with the 40-metre Rain Vortex is linked to Terminals 1, 2 and 3. On a long layover, remember the plan's days start the first time the eSIM connects. When your plan starts
• Johor Bahru (Malaysia): KTM's Shuttle Tebrau train runs from Woodlands to JB Sentral in about 5 minutes. The new RTS Link, from Woodlands North to Bukit Chagar, is now targeted for February 2027. A Singapore plan doesn't work there: see the Malaysia eSIM page.
• Batam and Bintan (Indonesia): ferries to Batam and Karimun leave from HarbourFront, and to Batam and Bintan from Tanah Merah. Those islands are in Indonesia, so you need an Indonesia eSIM or a regional plan.

Getting around

The MRT and buses take contactless bank cards and phone wallets, including foreign-issued Visa, Mastercard and American Express on Apple Pay, Google Pay or Samsung Pay. Visa and Mastercard cards issued abroad pay a S$0.60 admin fee per day of travel, and Maestro and Cirrus cards don't work. Tap in and out with the same card or phone. Taxis and ride-hailing cars fill the gaps late at night, after the MRT stops.

Apps worth having

• Grab does rides, food delivery and payments in Singapore. Gojek books cars and taxis, and since April 2024 some GoCar trips are served by ComfortDelGro's Zig. Zig and TADA also pick up at Changi. Set them up at home: sign-up sends a text code to your usual number, so keep that line on for texts.
• Google Maps or Citymapper for MRT and bus routes, with live times.
• WhatsApp for hotels, tours and restaurant bookings. Log in before you leave, and keep your WhatsApp number working abroad.

SIM and phone rules

Local SIMs are registered with your passport. Singtel's tourist plans are for foreign passport holders, and you show the original at collection; registration and activation happen there. Each person can register up to three prepaid SIMs.

A passport registration lasts 30 days. Singtel and M1 both say a SIM registered with a passport is valid for 30 days; keeping it longer needs a Singapore ID or work pass. Singtel also says calls and texts on its tourist SIM aren't on by default; you enable them at a hi! retailer with your passport.

Tourist eSIMs from the operators still check your ID: StarHub asks you to verify on the phone you bought it on, and activate it in Singapore within 18 days of purchase. A travel eSIM installed at home roams as a visitor, so there's no counter, no ID check and no 30-day clock.

Common mistakes

• Leaving Data Roaming on for your home line. Your carrier's daily charges start the moment it connects. Why roaming goes on for the kimsim line only
• A Singapore-only plan for a JB day trip or a Batam ferry. It stops at the border. How regional plans work
• Starting the plan on a short layover. Keep the kimsim line off if you're only passing through Changi. If your plan started early
• No way to call for help. Singapore's police number is 999, and ambulance and fire is 995. A data-only eSIM can't dial them, so use your home line or any local phone.

How we put this page together

We checked Singapore's immigration and transport authorities, Changi Airport's own pages, the operators' tourist SIM pages, carriers' roaming price pages and the other sources noted above on 1–2 November 2026, and we'll keep them up to date. We haven't measured speeds or coverage in Singapore ourselves, so coverage notes are general guidance, not a map. kimsim sells the eSIMs on this page.
