Best eSIM for Singapore 2026: Airalo, Holafly & Ubigi Review
Quick answer: The best eSIM for Singapore depends on whether you prioritize a cheap fixed-data plan, unlimited data, hotspot sharing, or a local carrier package. For most tourists who mainly need maps, ride-hailing, messaging, social media and tethering, my practical pick is the eSIMKitStore Singapore eSIM. Its seven-day unlimited plan currently costs US$13, supports hotspot use, requires no passport or identity verification, and can be installed before departure.
Airalo and Ubigi offer cheaper fixed-data options for light users. Holafly is useful when you want to choose an exact trip length, while Singtel offers a local-carrier tourist eSIM that requires passport registration.

How I Compared These Singapore eSIM Plans
This comparison uses information published on each provider’s official website rather than relying only on advertised “from” prices. I checked:
- Published package prices and validity periods
- Fixed, unlimited and fair-use data terms
- Local partner networks
- Hotspot and data-sharing policies
- Passport or identity-verification requirements
- Local number, call and SMS availability
- QR-code delivery, installation and activation timing
This is not a laboratory speed test. Actual performance can vary with your phone, 5G support, location, building conditions, network load and local coverage.
Singapore eSIM Price and Plan Comparison
| Provider | Example plan | Official price | Network and key terms | Best for |
|---|---|---|---|---|
| eSIMKitStore | 7 days, unlimited data | US$13 | SIMBA/StarHub; hotspot supported; no ID verification; data only | Travelers wanting affordable unlimited data without passport registration |
| Airalo | 7 days, unlimited data | US$27 | Singtel plus one other local network; app-based management | Travelers already using the Airalo app |
| Holafly | 7 days, unlimited data | US$27.50 | Singtel; hotspot sharing limited to 1GB per day | Travelers wanting unlimited data with flexible trip lengths |
| Ubigi | 7 days, unlimited data | US$19 | SIMBA/StarHub; 20GB at full speed, then 2Mbps; data sharing allowed | Travelers wanting a reusable eSIM with app top-ups |
| Singtel | 7 days, 500GB | S$10 | Singtel 5G+; tourist eSIM is data only; passport registration required | Travelers who prefer buying directly from a local carrier |
Comparison note: Singtel is a local tourist product priced in Singapore dollars and requires identity registration, so its headline price is not directly comparable with registration-free international travel eSIMs. Airalo and Ubigi also sell cheaper fixed-data plans.
Why I Choose eSIMKitStore Singapore eSIM
I do not choose an eSIM solely by the lowest advertised starting price. For an ordinary Singapore trip, I care more about whether I could unexpectedly run out of data, whether I must upload my passport, whether I can install the eSIM before flying, and whether the validity period starts too early.
Based on those criteria, eSIMKitStore is my practical choice for a roughly one-week, data-focused trip:
- US$13 for seven days of unlimited data: That is below the reviewed seven-day unlimited plans from Airalo at US$27, Holafly at US$27.50 and Ubigi at US$19.
- No passport or identity verification: This removes the registration step required by Singtel’s tourist eSIM.
- Hotspot support: The connection can be shared with a laptop, tablet or another device.
- SIMBA/StarHub connectivity: The product page lists 5G/LTE service, subject to local coverage and device support.
- Validity starts on the first local connection: You can install it on reliable Wi-Fi before leaving home.
- Simple plan selection: Every five-, seven-, ten-, fifteen- and thirty-day option includes unlimited data, so there is no need to estimate a precise gigabyte allowance.
There are clear trade-offs. This is a data-only eSIM with no Singapore phone number, calls or SMS. It cannot be topped up, and the product is non-refundable after the QR code has been sent. If you need ordinary calls, local SMS or an extendable plan, a local carrier or another refillable service may suit you better.

Airalo Singapore eSIM Review
Airalo is one of the most visible brands in Singapore eSIM search results. Its main advantages are a mature app, support for many destinations, and a choice between fixed and unlimited packages. Airalo’s Singapore page currently lists Singtel plus one other local partner network.
- 3 days unlimited: US$11.50
- 5 days unlimited: US$18.50
- 7 days unlimited: US$27
- 10 days unlimited: US$34.50
- 15 days unlimited: US$48
- 30 days unlimited: US$69
Airalo also advertises Singapore fixed-data packages from US$4, which may be economical if you only need maps, WhatsApp and occasional browsing. For seven days of unlimited data, however, eSIMKitStore’s US$13 price is substantially lower.
Holafly Singapore eSIM Review
Holafly focuses on unlimited data with trip-length customization. Its Singapore eSIM uses the Singtel network, supports 5G where available as well as 4G/LTE, and is delivered by email.
- 3 days: US$11.90
- 5 days: US$20.50
- 7 days: US$27.50
- 10 days: US$36.50
- 15 days: US$50.50
- 30 days: US$73.90
Holafly’s strengths include more flexible duration selection and 24/7 support. Its current Singapore product page limits hotspot sharing to 1GB per day, so unlimited phone data does not mean unlimited tethering for a laptop or another traveler.
Ubigi Singapore eSIM Review
Ubigi is useful for travelers who want to keep one eSIM installed and purchase new packages for future destinations. Smartstart begins the plan after arrival in a covered destination, while the Ubigi app can be used to check usage and purchase top-ups.
- 3GB for 15 days: US$6
- 10GB for 7 days: currency-converted pricing may vary between official regional pages
- Unlimited data for 7 days: US$19
Ubigi’s seven-day unlimited plan includes 20GB at full speed, after which the connection is optimized to 2Mbps for the rest of the validity period. It allows data sharing and uses SIMBA and StarHub. The US$6 3GB package is attractive for light users, while heavy users should account for the unlimited plan’s speed policy.
Singtel Tourist eSIM Review
Singtel is a Singapore network operator. Its current S$10 seven-day tourist plan includes 500GB of 5G+ data for use in Singapore, Malaysia, Indonesia, Thailand and Hong Kong.
However, the Singtel tourist eSIM is restricted to foreign passport holders and requires identity registration. Singtel’s terms also state that the eSIM version is data only. Plan validity starts from purchase rather than waiting for the traveler to arrive in Singapore.
Singtel can be a good choice if you specifically want a local-carrier package with a very large regional allowance. If you prefer no passport registration, advance installation and validity that starts after connecting locally, eSIMKitStore is simpler.
Choosing a Singapore eSIM by Trip Type
Three- to Five-Day City Break
If you only use Google Maps, Grab, WhatsApp and attraction websites, a small Airalo or Ubigi package may be sufficient. If you expect to stream video, upload many photos or share a hotspot, eSIMKitStore’s US$10 five-day unlimited plan makes the total cost easier to predict.
One-Week Singapore Holiday
A one-week trip is where the US$13 eSIMKitStore plan is especially competitive. It costs less than the reviewed seven-day unlimited packages from Airalo, Holafly and Ubigi while requiring no identity verification and supporting hotspot sharing.
Business Travel or Remote Work
Check tethering rules as well as total data. eSIMKitStore supports hotspot use. Ubigi allows data sharing but reduces its seven-day unlimited plan to 2Mbps after 20GB of full-speed use. Holafly limits sharing to 1GB per day. For critical video meetings, keep reliable hotel or office Wi-Fi as a backup.
Travelers Who Need a Singapore Phone Number
Most international travel eSIMs in this comparison are data-only. eSIMKitStore explicitly includes no local number, calls or SMS. If you must receive ordinary calls or local text messages, select a carrier product that provides those services and allow time for passport or identity registration.
How to Install a Singapore eSIM
- Confirm that your phone is unlocked and eSIM compatible. You can check the eSIM-compatible device list.
- Choose a validity period that covers your complete Singapore trip.
- After receiving the QR code by email, add the eSIM while connected to stable Wi-Fi.
- Select the Singapore eSIM as the line used for mobile data.
- Turn off data roaming on your primary SIM to avoid home-carrier roaming charges.
- After landing, enable the travel eSIM and turn on data roaming for that line.
Activation rules vary. eSIMKitStore begins the plan after the first connection to a Singapore network. Holafly and Ubigi also center activation around arrival or connection in the covered destination. Singtel tourist-plan validity may begin at purchase. Do not assume every eSIM starts in the same way.
For illustrated instructions, see the eSIM installation and activation guide.
Singapore eSIM Frequently Asked Questions
Can I get an eSIM for Singapore as a tourist?
Yes. Tourists can buy a Singapore eSIM online before departure as long as their phone is unlocked and supports eSIM. eSIMKitStore, Airalo, Holafly and Ubigi offer data-only travel options. Singtel also sells a tourist eSIM but requires passport registration.
Which SIM is best for tourists in Singapore?
For data-only travel, eSIMKitStore is a strong choice for most visitors because its seven-day unlimited plan currently costs US$13, requires no identity verification and supports hotspot use. Light users can consider Airalo or Ubigi, Holafly suits flexible trip lengths, and Singtel suits travelers who specifically prefer a local carrier.
What is the cheapest eSIM plan in Singapore?
Among the official prices checked for this comparison, Airalo advertises Singapore eSIM packages from US$4, while Ubigi lists 3GB for 15 days at US$6. The lowest purchase price is not always the lowest total cost. If you stream, make video calls or tether another device, eSIMKitStore’s US$13 seven-day unlimited plan may cost less than purchasing additional data.
Which SIM-only plan is the best in Singapore?
Short-term visitors usually do not need a monthly SIM-only contract. A prepaid data eSIM can be purchased and installed before departure. Choose eSIMKitStore for registration-free unlimited data, or compare local Singtel, StarHub, M1 and SIMBA plans if you need a local number or longer-term service.
Is Airalo or Holafly better for Singapore?
Airalo is better suited to travelers who want to manage fixed, regional and global packages in one app. Holafly is better suited to travelers who want unlimited data with customizable duration. Their current seven-day unlimited prices are US$27 and US$27.50 respectively, compared with US$13 from eSIMKitStore.
Do I need a passport to activate a Singapore eSIM?
It depends on the provider. eSIMKitStore states that identity verification is not required. Singtel tourist eSIMs are available to foreign passport holders and require registration. Check the latest eKYC or registration terms for any other plan before paying.
Does a Singapore travel eSIM include a phone number?
Not necessarily. eSIMKitStore is explicitly data only and includes no phone number, calls or SMS. The Singapore travel plans from Airalo, Holafly and Ubigi are also primarily designed for mobile data. Internet-based services such as WhatsApp, LINE, WeChat and FaceTime can still use your existing account.
Can I share a Singapore eSIM through hotspot?
It depends on the provider. eSIMKitStore supports hotspot use, Ubigi allows data sharing, and Holafly currently permits 1GB of hotspot sharing per day on its Singapore plan. If you plan to connect a laptop or share data with other travelers, check the tethering allowance and fair-use terms before purchasing.
Final Verdict: What Is the Best eSIM for Singapore?
No single plan is best for every traveler, but the decision can be simplified:
- For light usage and the lowest entry price: Airalo or Ubigi fixed-data plans
- For customizable duration and unlimited data: Holafly
- For a local-carrier package with a large regional allowance: Singtel
- For affordable unlimited data, no passport registration and hotspot support: eSIMKitStore
For a typical five- to ten-day Singapore trip, eSIMKitStore would be my first option. It does not have the lowest advertised starting price, but when I compare unlimited data, the US$13 seven-day price, no identity verification, hotspot support and activation after local connection, it provides a clearer and more complete value proposition.
