Questions about eSIM in Singapore

An eSIM is a SIM that arrives as a QR code instead of a plastic card. You scan it at home on Wi-Fi and keep the line off until you land; in Singapore, turn it on and choose it for mobile data. It runs on a Singapore network, and your usual SIM stays in the phone, so calls and texts to your own number keep arriving.

The one you can check before you pay: which Singapore network it runs on, the data and the days, and the price in US dollars with tax. The plans here run on Simba, StarHub or Singtel, are data only, cost from US$4.88 with tax, and are refunded in full if they do not work and cannot be fixed.

Yes. Pick a plan on VietSIM, the same company's store for Vietnam and Asia: this site's buttons open the store's Singapore page, and the QR code appears right after payment. Install it at home on Wi-Fi before you fly.

Its Singapore network, one of Simba, StarHub or Singtel; the data and the number of days; that it is data only; and the price in US dollars with tax.

No, if the eSIM is installed: you switch it on after landing, with nothing to collect at the airport. A prepaid SIM card bought in Singapore is registered at the point of sale, and visitors register theirs with a passport. The eSIM plans here are data only, so your own number stays in the phone for calls and texts.

Most visitors do: the SG Arrival Card is free on ICA's official portal and filed within the 3 days before you arrive. Keep the acknowledgement on your phone, and have your passport ready at immigration. It is not a visa.

It is +65. From abroad, dial +65 and then the eight-digit number exactly as written: Singapore has no area codes and no trunk prefix, so there is no 0 to drop. Inside Singapore, dial the number as written, all eight digits.

The Singapore dollar, written SGD and S$, divided into 100 cents. Cards and contactless payments are everyday options, on the MRT and buses too; cash stays legal tender, and some small shops and stalls will want it, so keep some. A vendor may set conditions, such as the denominations it accepts, with a written notice.

Type G: three rectangular pins, the same shape as in the UK, Malaysia and Hong Kong. The supply is 230 volts at 50 Hz, and a phone or laptop charger rated 100 to 240 volts needs only the right plug shape.

Take normal care: Canada advises taking normal security precautions in Singapore, and notes petty crime such as pickpocketing and purse snatching around airports, hotels and tourist areas, so keep bags and phones secure. Emergency: 999 police, 995 fire and ambulance.

Yes: your phone keeps its data on the trains and in the stations wherever the network's coverage holds, and each operator publishes its own coverage map. The fare is separate: contactless bank cards are accepted at the MRT gates and on buses, so the eSIM is not needed to ride.

The QR code comes up on screen the moment payment is done; save the page link, since that is where the code waits. The install window is 30 days from buying. An eSIM that does not work and cannot be fixed is refunded in full.
