Singapore SIM card for tourists 2026: airport or eSIM?
Where to buy a SIM card in Singapore, what the counter asks for, coverage in Singapore, and when an eSIM installed before you fly is the better buy.
Short answer: A tourist SIM card in Singapore is bought at a counter after you land in Singapore; a ONE eSIM plan for Singapore is installed at home on Wi-Fi, works the moment you land and leaves your own SIM and number in place. Both work in every city in this guide.
Landing in Singapore and wondering whether to queue for a SIM card? This is how buying one works in Singapore in 2026, what the counter will ask you for, and when an eSIM bought before you fly is the better deal.
Where to buy a SIM card in Singapore
Singtel, StarHub and M1 sell tourist SIM cards at shops and money changers in the Changi arrivals halls and in 7-Eleven stores across the city. Every card is registered to your passport, at the counter or online with a photo of the passport page. Tourist packs are sold for a set number of days and usually include a little local calling.

An eSIM is a plan downloaded onto a phone that supports it, which is every iPhone since the XS and most Android flagships since 2020. You install it on Wi-Fi at home, keep the line switched off, and turn it on when the plane lands in Singapore. The plan starts the first time it connects, not when you buy it.
Coverage in Singapore, Changi and Sentosa and beyond
Both a local SIM and a travel eSIM run on the same networks in Singapore, so coverage is about the operator, not the kind of SIM. Our plans name their operator and whether it runs 3G, 4G or 5G; each plan card shows its best generation. In Singapore, Changi, Sentosa and Jurong you will have a full signal from any of them.
FAQ: SIM cards and eSIMs in Singapore
- Is a Singapore SIM card registered to my passport? Yes, every prepaid SIM in Singapore is. A travel eSIM is bought before you fly and needs no registration on arrival.
- Can I buy a SIM card in transit at Changi without passing immigration? Not usually: the SIM sellers are landside, after immigration. An eSIM bought before the trip works in the transit area too.
Before you fly
- Check your phone supports eSIM and is not carrier-locked (our device page lists every model).
- Buy the plan a few days before the trip and install it on home Wi-Fi; the QR code arrives by email in minutes.
- Keep the travel line off until you land, then turn it on with data roaming enabled for that line only.
- Leave your home SIM in for calls and texts; set the eSIM as the mobile data line.
