🇸🇬 eSIM for Singapore
Singapore has excellent infrastructure and is often a stopover rather than a destination — which makes a short, cheap data plan the sensible choice over a physical SIM you will use for two days.

Using your eSIM in Singapore
Singapore is usually two days on the way to somewhere else, which makes a short, cheap plan the right size and a physical SIM the wrong one. Coverage is essentially universal, including on the MRT. Networks named on the plan: M1, SingTel, Starhub, StarHub and TPG Telecom.
Some plans here include 5G (13 of 14); the others are 4G, so check the speed line on the plan if it matters to you. A long layover is the common case: the 500 MB plan over 1 day at $3.28 covers a stopover, and it can be installed at the gate on the airport wi-fi if you forgot at home. Data roaming on for the Num line, off for your home SIM, APN automatic.
The smallest plan is 500 MB over 1 day ($3.28); the largest is 50 GB over 180 days ($92.25). Every plan here can be topped up from the app without reinstalling anything.
Who this suits: a stopover or a short business trip. If Singapore is the start of Malaysia and Thailand as well, the Asia regional plan covers all three on one eSIM and saves installing at each border.
Practical notes for Singapore
- Coverage is essentially universal, including on the MRT.
- Long layovers are a common use case: a one- or three-day plan usually covers it.
- If you are continuing into Malaysia or Thailand, check a regional Asia plan.

Questions about Singapore
How much does an eSIM for Singapore cost?
Plans start at $3.16. The table on this page shows current prices — 14 options ranging from short trips to month-long stays. These are the prices you pay in the app; there are no separate activation or delivery fees.
Will my phone work with a Singapore eSIM?
Most iPhones from the XR and XS onward support eSIM, and the handset must be carrier-unlocked. Check the compatibility page for the full list before you buy.
When does the plan start counting down?
Validity begins when the eSIM first connects to a network in the coverage area, not when you buy it. You can install it before you travel and it will wait until you land.
Can I keep my normal number while using it?
Yes. The Num eSIM runs alongside your existing SIM, so calls and texts on your usual number keep working while data runs over the travel plan. Turn your normal line's data roaming off to avoid a roaming bill.
Can I add more data if I run out?
Yes — reloadable plans can be topped up from inside the app without buying a new eSIM or reinstalling anything.
Is there an unlimited data eSIM for Singapore?
Num does not sell unlimited plans for Singapore. The closest are the daily-allowance plans, such as 2 GB per day, which give a fixed amount each day for the length of the trip. For most travellers the fixed bundles, from 500 MB to 50 GB, are better value.
Which networks does a Num Singapore eSIM use?
It connects to M1, SingTel, Starhub, StarHub and TPG Telecom and picks the strongest available network automatically. 13 of the 14 plans support 5G; the rest run on 4G/LTE.
Do I get a Singapore phone number with the eSIM?
No. Num eSIMs are data-only. Your own number stays active on your existing SIM for calls and texts, and WhatsApp, iMessage and other messaging apps keep working over the eSIM's data. If you need a local number, see our guide to eSIMs with a phone number.
What is the best eSIM for Singapore?
It depends on how long you stay and how much you use maps and video. On this page the best value per gigabyte is 10 GB total for 30 days at $9.63 ($0.96); the trip-length picks match a plan to a weekend, a week, two weeks and a month. The comparison page sets Num's prices against Airalo, Saily, Nomad, Simpal, Maya at matched plan sizes, including the sizes where we are not the cheapest.
