Indian travellers can land at Changi and be online in ten minutes in 2026. For Singapore, buy a tourist prepaid SIM or eSIM from Singtel, StarHub or M1 at the arrival halls or before departure. Physical SIMs start around 12 to 15 SGD for 7 days with 100 GB local data, eSIMs are 10 to 18 SGD for similar 7 to 15-day packs, and all include local calls and SMS with 5G where your handset supports it.
The simplest choice in 2026 is an eSIM bought online before you fly and activated over Changi WiFi on landing, because you keep your Indian SIM active for OTPs on the second slot. If your phone is locked or not eSIM compatible, the Changi counters in Terminals 1 to 4, plus Cheers and 7-Eleven airside, sell tourist SIMs with passport registration on the spot. Coverage is near-universal across the island, including MRT tunnels.
Do Indians need a SIM or eSIM for Singapore in 2026?
You do if you want cheap data for Grab, Maps and OTPs. International roaming from Indian carriers works in Singapore, but even discounted roaming is usually 6 to 10 times the price per GB of a local tourist pack and often throttles to 4G. A local SIM or eSIM gives you local number for restaurant bookings, 100 GB+ data for a week for about 900 to 1,100 INR, and hotspot for laptops.
Singapore has one of the highest mobile penetrations in Asia, with all three operators offering nationwide 5G standalone coverage by 2025 according to the Infocomm Media Development Authority. Practically, you will see 5G on Orchard Road, Marina Bay and Changi, and consistent 4G on Sentosa and in the MRT.
Where to buy a SIM at Changi and in the city?
At Changi: after immigration, look for Singtel and StarHub counters in Arrivals (T1, T2, T3, T4) and Cheers convenience stores airside and landside. They are open around the clock for early-morning IndiGo and Air India arrivals. Bring your passport - Singapore law requires ID registration for every SIM and eSIM. Tellers scan the passport, register the number and hand you a working SIM in under five minutes.
In the city: any Singtel Shop, StarHub Shop or M1 Shop in Orchard, Bugis or Mustafa Centre, plus 7-Eleven and Cheers with the telco signage. Mustafa in Little India is convenient for Indian travellers who want to compare all three operators on one street. Avoid buying from unbranded stalls that do not register the passport - the SIM may be blocked.
Which tourist plan is best: Singtel vs StarHub vs M1?
All three are solid, but they tilt slightly different. Singtel hi!Tourist has the widest coverage and the fastest 5G peak rates, useful if you hotspot a laptop. StarHub Prepaid Tourist often bundles more IDD minutes to India and extra Changi WiFi. M1 Tourist SIM tends to be the cheapest for pure data. In 2026 typical bandings are:
| Operator | Popular 2026 tourist pack | Data and validity | Price band |
|---|---|---|---|
| Singtel hi!Tourist | 7-day / 15-day | 100 GB local 5G + 30 min local calls | 12 to 18 SGD |
| StarHub Prepaid Tourist | 7-day / 28-day | 100 to 120 GB + IDD to India + local calls | 12 to 32 SGD |
| M1 Tourist SIM/eSIM | 7-day / 12-day | 100 GB + local calls and SMS | 10 to 15 SGD |
For a four-day Indian city break, the 7-day 100 GB pack is more than enough - most users burn 2 to 4 GB per day on maps and video. For a seven to ten-day Singapore-Malaysia loop, pick the 15 or 28-day pack so you do not re-register at the border.
How do you activate an eSIM and keep your Indian number?
Before you fly: buy the eSIM online from Singtel, StarHub or M1 or via their Lazada or Shopee storefronts. You receive a QR by email after passport e-KYC. On your iPhone or Android, go to Settings - Mobile - Add eSIM - Scan QR while on WiFi, install the profile, and label it Singapore.
At Changi: connect to Changi WiFi (free, no registration), scan the QR, wait 60 to 90 seconds for activation, then switch Data Roaming on for the Singapore line only. Keep your Indian SIM's data roaming off but leave voice and SMS on for OTPs, and turn on WiFi Calling so OTPs arrive over the Singapore data. Dual-SIM iPhones and most Samsung, OnePlus and Pixel phones from 2021 onwards support this.
If your phone shows "Carrier Lock" or "SIM locked", you cannot add an eSIM until your Indian carrier unlocks it - call Airtel or Jio before departure. Also check that your handset supports eSIM and 5G band n78 (3500 MHz), which all three Singapore operators use.
What about hotspot, calls to India and validity?
All 2026 tourist packs allow hotspot sharing to laptops and family phones with no extra fee, which is how most Indian families share one 100 GB pack across two phones. Calls to India are cheapest via WhatsApp or FaceTime Audio over data - local IDD minutes are included but at 2 to 5 cents per minute to India they add up. Tourist SIMs expire automatically at 23:59 on the last validity day and number recycling is fast, so do not link your Singapore UPI or bank OTP to the tourist number.

Frequently asked questions
Can Indians buy a Singapore SIM at Changi Airport at 02:00?
Yes. Singtel and StarHub counters and Cheers stores in T1 to T4 are staffed for late-night arrivals from India. Bring your passport for registration. If the counter queue is long, use the free Changi WiFi to activate a pre-bought eSIM QR while you wait.
Is eSIM better than physical SIM for Singapore?
For most Indians, yes. An eSIM arrives by email before departure, you keep your Indian SIM active for OTPs in the second slot, and you avoid queuing at Changi. Choose physical SIM only if your phone does not support eSIM or is carrier-locked.
How much data do I need for four days in Singapore?
Most travellers use 2 to 4 GB per day for maps, Grab and social video. A 7-day 100 GB tourist pack for 12 to 15 SGD (about 900 to 1,100 INR) is more than enough and leaves hotspot headroom for family sharing.
Will my Indian OTPs still arrive if I use a Singapore SIM?
Yes if you keep your Indian SIM inserted with voice and SMS roaming on and WiFi Calling enabled. OTPs arrive as SMS over the Singapore data via WiFi Calling. Turn data roaming off for the Indian line so you are not charged for background data.
