What Singapore data actually costs
Singapore travel eSIM prices look random until you convert every plan to one number: the real cost per gigabyte. Here is what that reveals right now.
The cheapest plan at each size, 30 days
| Data | Cheapest provider | Total | Price per GB | |
|---|---|---|---|---|
| 50 GB | Nomad | $31 | $0.62/GB | Get plan ↗ |
| 25 GB | Ubigi | $22 | $0.88/GB | Get plan ↗🏷 10% off with code TRAVELCITY10 |
| 20 GB | Sim Local | $18.50 | $0.93/GB | Get plan ↗🏷 10% off with code ATESIM |
| 10 GB | Sim Local | $12.75 | $1.27/GB | Get plan ↗🏷 10% off with code ATESIM |
| 5 GB | Nomad | $9 | $1.80/GB | Get plan ↗ |
| 1 GB | Yesim | $3.67 | $3.67/GB | Get plan ↗🏷 15% off with code TRAVELCITY |
Cost per GB rises from $0.62/GB at 50 GB to $3.67/GB at 1 GB. Buying a little more data than you expect to use is almost always cheaper per gigabyte than buying exactly what you need.
The "unlimited" trap
The same words, unlimited for 30 days, cover a wide price range, and most plans slow down after a daily threshold that the label hides.
| Provider | Unlimited, 30 days | Fair-use cap | |
|---|---|---|---|
| Ubigi | $49 | Confirming | Get plan ↗🏷 10% off with code TRAVELCITY10 |
| Maya | $49.99 | Confirming | Get plan ↗🏷 10% off with code ATESIM |
| Yesim | $55.13 | Confirming | Get plan ↗🏷 15% off with code TRAVELCITY |
| Airalo | $69 | Confirming | Get plan ↗ |
| Saily | $71.99 | Confirming | Get plan ↗ |
Unlimited 30 day plans run from $49 to $71.99, a spread of about 47 percent, for a label that means the same thing on paper. Check the daily cap before you buy, especially if you plan to tether a laptop.
Do not overpay for coverage you will not use
If your whole trip is in Singapore, a Singapore only plan is far cheaper per gigabyte than a Asia or global plan carrying the same data. Same provider (Sim Local), same 20 GB, 30 days:
| Sim Local plan | Price | Price per GB | |
|---|---|---|---|
| Singapore only | $18.50 | $0.93/GB | Get plan ↗🏷 10% off with code ATESIM |
| Asia | $35 | $1.75/GB | Get plan ↗🏷 10% off with code ATESIM |
| Global | $35 | $1.75/GB | Get plan ↗🏷 10% off with code ATESIM |
A Singapore only plan costs much less per gigabyte than a regional or global plan with the same data. Only pay for the wider plan if you are actually crossing borders on this trip.
Which network does your Singapore eSIM use?
This is the question that decides your real signal, and almost no comparison site answers it. Your travel eSIM connects to one or more local networks as a visitor, and that choice matters the moment you leave the big cities, because rural coverage varies a lot between them.
| Provider | Host network | Status |
|---|---|---|
| Airalo | StarHub | Confirmed |
| GigSky | Not publicly disclosed | Confirming |
| Ubigi | Simba and StarHub | Confirmed |
| Nomad | Singtel | Confirmed |
| Saily | Not publicly disclosed | Confirming |
| Yesim | Not publicly disclosed | Confirming |
All three national networks cover the whole island, so any of these plans will perform well; Nomad (Singtel), Airalo (StarHub) and Ubigi (Simba and StarHub) name their host carrier, making them the safest picks if you want a known network.
Coverage by where you are going
- The national networks Singtel, StarHub and M1 all give near-total island coverage, so signal is strong from Marina Bay to Changi and out to Sentosa, which runs on the same networks.
- Singtel passed 95% nationwide standalone 5G coverage in July 2022, and the StarHub and M1 joint venture rolled out 5G alongside it, so 5G is available across the island today.
- The MRT has full mobile coverage in underground stations and tunnels, including 5G, so you stay connected below ground.
- A Singapore-only plan does not work across the Johor Bahru causeway into Malaysia or on the Batam and Bintan ferries to Indonesia, and it may try to roam at high cost, so pick a regional Asia plan or a Singapore-Malaysia bundle if you are crossing the border.
Travel eSIM vs a local Singapore SIM
A travel eSIM is the simplest option for a short visit. You install it before the flight and it connects when you land, with no passport registration required. A mid-size data plan costs a few US dollars, and providers such as Nomad and Airalo tell you which host network you are on.
Local prepaid tourist plans give large data allowances but need registration with your passport after you arrive, since SIM registration in Singapore is mandatory and can only be done on the ground. Singtel and M1 sell tourist eSIMs while StarHub does not, for example Singtel at SGD 12 for 100GB over 14 days. Singapore is not part of any roaming union, so a local plan is for domestic use only and will not follow you across the border.
Quick rule: Short trip, buy a travel eSIM before you fly; long stay or very heavy data use, get a local Singtel or M1 tourist plan on arrival.
Singapore's three national networks are Singtel, StarHub and M1, and budget data comes from MVNOs such as GOMO, which runs on the Singtel network.
How a Singapore travel eSIM works
A travel eSIM replaces expensive roaming with a cheap local data plan you activate in seconds. There is no plastic SIM and no airport queue. Roaming with your home carrier can run 6 to 12 dollars a day, so a week easily tops 50 to 80 dollars for service you already pay for at home.
Three things to get right:
- Check your phone supports eSIM before you buy.
- Install the eSIM at home over WiFi, but wait to activate it until you land, because the validity period usually starts on activation.
- Keep your physical SIM in the phone for calls and texts on your normal number.
How we rank Singapore eSIMs
Every plan on this page is sorted by real price per GB (total price divided by included data, normalised to USD), so a cheap-looking 1 GB plan cannot outrank a better-value 10 GB one. We refresh prices daily and only list providers with a track record of activating on arrival. We earn a small affiliate commission when you buy through our links. It funds the price tracking and never changes the order you see.
Singapore travel eSIM FAQ
Which network will my eSIM use in Singapore?
It depends on the provider. Nomad runs on Singtel, Airalo's Connect Lah plan runs on StarHub, and Ubigi uses Simba and StarHub. GigSky, Saily and Yesim do not publicly name a single Singapore carrier, but all three national networks cover the whole island, so coverage is strong either way.
Will my Singapore eSIM work in Malaysia or Indonesia?
No. A Singapore-only plan stops working once you cross the Johor Bahru causeway into Malaysia or take a ferry to Batam or Bintan in Indonesia. It may also try to roam at high cost. If you are visiting neighboring countries, use a regional Asia plan or a Singapore-Malaysia bundle instead.
Should I get a regional Asia plan instead of a Singapore-only plan?
If Singapore is your only stop, a single-country plan is usually cheaper per GB. If your trip also takes in Malaysia, Thailand, Indonesia or other nearby countries, a regional Asia plan is better value and saves you swapping eSIMs at each border.
Is there 5G, and does it work on the MRT?
Yes. Singapore has had nationwide standalone 5G since 2022, and coverage reaches most of the island. The MRT has full mobile coverage in underground stations and tunnels, including 5G, so you stay online below ground.
Do I need to register my eSIM with my passport?
Not for a travel eSIM from providers like Airalo, Nomad or Ubigi; you just install it and go. Local Singtel and M1 tourist plans do require passport registration, which can only be completed after you arrive in Singapore.
Is a local SIM cheaper than a travel eSIM?
Local tourist plans give more data per dollar, for example Singtel's SGD 12 for 100GB, but they need in-person or app registration on arrival. For a short trip the convenience of a travel eSIM usually outweighs the saving, while long or data-heavy stays lean toward a local plan.
