Singapore Tech For Visitors: Best Tourist SIM Cards And eSIMs

Photo Credit: DFNIOnline

Singtel, StarHub and M1 each sell tourist plans, and entry prices start around S$12 according to Changi Airport’s listing as cited by Trifa in 2026. M1 lists a S$13 eSIM with 250 GB for 30 days, but eSIMs for Singapore are data-only, with no local number or SMS. If you want the best mix of Singapore tech and simple Singapore travel, pick an eSIM before you fly, or a physical SIM from a shop and carry your passport.

This guide compares the main options and lists what to check before you pay.

Which Operators Sell Tourist SIM Cards In Singapore?

Singapore has three main mobile operators for tourists: Singtel, StarHub and M1, according to Saily’s guide. A fourth, Simba, also offers tourist SIM packages, according to The BitJoy’s 2026 guide.

Changi Airport lists Changi Recommends counters, Cheers and 7-Eleven stores, and money changers across Terminals 1 to 4, according to Trifa. Trifa adds that StarHub has counters in Terminals 1, 2 and 3. City stores in malls and MRT stations also sell SIMs, according to The BitJoy.

A short answer to “who should I buy from?” is any of the three. Singtel and StarHub list S$12 to S$50 plans at Changi, while M1 lists S$12 to S$30, according to Trifa. Pick by data allowance and number of days, not by brand name alone.

Should I Choose An eSIM Or A Physical SIM?

An eSIM is a digital SIM you install by scanning a code, and you can buy it online before you fly. It lets your phone connect when you land. Singapore eSIMs are data-only, according to Trifa, so you will not get a local phone number or text messages. Airalo and Holafly eSIMs run on the Singtel network, according to the same source.

A physical SIM gives you more options. Bento.travel notes that a local SIM needs ID registration, so you must show your passport. A physical SIM also suits you if you need a Singapore number for deliveries or bookings.

Here is a quick comparison.

Is It Cheaper To Buy At The Airport Or In The City?

Guides disagree here. TravJoy says the same Singtel 100 GB SIM that costs about S30inacitystorecancostS70 at the airport. Trifa and Changi’s listing show S$12 as the entry price at the airport.

My advice is simple. Compare the exact plan, validity and data amount before you pay, and check whether the price is for a 14-day, 28-day or longer plan. A cheaper plan with fewer days may cost more per day.

A quick sum helps. An S$12 plan that lasts 14 days works out to under one dollar a day, while a S$13 plan that lasts 30 days costs less than half that. The cheapest sticker price is not always the best value.

Here is the blunt limitation. Operator plans, promotions and eSIM rules change, and published guides do not agree on StarHub’s eSIM availability. Check the operator’s page the week before you fly.

What Singapore Tech Details Should I Check Before Buying?

Look at three things: data, days and activation. Bento.travel says an airport tourist SIM can include 100 GB for 14 days at around S12.TrifasaysM1’sS13 eSIM plan offers 250 GB for 30 days, and that StarHub’s tourist eSIMs must be activated within 18 days of purchase.

If you use public transport every day, TravJoy points to a Singtel hi!Tourist EZ-Link 2-in-1 SIM that bundles mobile data with an MRT and bus transit card. It can save you from buying a separate card, so compare that bundle with the plain data plan.

Check your phone too. An eSIM needs a compatible, unlocked phone, and a physical SIM needs a free SIM slot. Install an eSIM on Wi-Fi before you fly, then switch it on after you land.

Last, think about calls. A data-only plan will not give you a Singapore number, so plan to use messaging apps for calls, or choose a physical SIM if you need a local number for deliveries.

Frequently Asked Questions

Do I need my passport to buy a SIM? Yes. Bento.travel says local SIM purchases need ID registration, and M1’s tourist page applies a passport rule. Carry your passport when you buy.

Does my phone need to be unlocked for an eSIM? Usually, yes. Check that your phone supports eSIM and is not locked to a home carrier before you buy.

When should I install an eSIM? Trifa says StarHub’s tourist eSIM must be activated within 18 days of purchase. Read the activation rules, because a plan can expire before you use it.

Can I top up if I stay longer? Some plans allow extension. The MoneyMax guide says some Singtel validity can be extended through the hi!App. Check the plan’s terms before you rely on it.
