The best eSIM for Singapore depends on whether you are spending a day in the city, staying for a week or continuing to Malaysia. A small prepaid package can cover maps, messages and ride bookings; a large local tourist plan makes more sense when you expect to use much more data on your phone.
Ubigi is our budget pick for 1GB or 10GB over seven days. Nomad eSIM is a strong choice for a 3GB stopover package and a Singapore–Malaysia itinerary. Singtel hi! Tourist offers a much larger allowance, but its validity starts at purchase and its eSIM should be treated as data-only on arrival.

Quick Verdict: Which Singapore eSIM Should You Choose?
- Staying airside at Changi: you may not need an eSIM. Free #WiFi@Changi is available in public and transit areas. Mobile data becomes more useful when you leave the airport.
- One day in the city: Ubigi’s 1GB / 7-day plan costs US$3.00, the lowest full purchase price among the fixed-data options compared here.
- Three days with around 3GB: Nomad eSIM SG–MY–TH costs US$6.00 for 30 days. Ubigi also costs US$6.00, with 15 days of validity and Singapore-only coverage.
- Seven days with around 10GB: Ubigi costs US$11.00. For a lighter 5GB week, Nomad eSIM and Airalo both cost US$9.00.
- A large allowance for your phone: Singtel hi! Tourist advertises 500GB for S$10 over seven days. Buy close to use and account for its passport and voice-service conditions.
- Day-based unlimited data: Holafly is an option for heavy phone use, with 1GB of hotspot data per day and a fair-use policy.

Singapore eSIM Prices for 1, 3 and 7 Days
These comparisons use complete packages for three illustrative needs: 1GB for a one-day stopover, 3GB for three days, and either 5GB or 10GB for a week. Prices and plan details were checked on October 5, 2026. Travel eSIM prices are in USD; Singtel’s SGD prices appear separately. Reader discount codes are excluded from the comparison. This is a comparison of published offers, not a Singapore speed test.
Fixed-data packages for a short stopover — total price in USD
| Provider | 1GB for a 1-day visit | 3GB for a 3-day visit |
|---|---|---|
| Ubigi | US$3.00 1GB / 7 days | US$6.00 3GB / 15 days |
| Nomad eSIM | US$4.00 1GB / 7 days SG–MY–TH | US$6.00 3GB / 30 days SG–MY–TH |
| Saily | US$3.99 1GB / 7 days | US$6.99 3GB / 30 days |
| Airalo | US$4.00 1GB / 3 days | US$6.50 3GB / 3 days |
| aloSIM | US$4.50 1GB / 7 days | US$7.00 3GB / 30 days |
Nomad eSIM’s regional 3GB package costs US$0.50 less than its Singapore-only 3GB / 30-day package. The regional plan is therefore worth considering even if you will stay entirely in Singapore. Airalo’s three-day package has less room for an early activation or an extended stay.
Fixed-data packages for seven days — total price in USD
| Provider | At least 5GB for the week | 10GB for the week |
|---|---|---|
| Ubigi | US$11.00 10GB / 7 days | US$11.00 10GB / 7 days |
| Nomad eSIM | US$9.00 5GB / 30 days SG–MY–TH | US$14.00 10GB / 30 days Singapore-only; sale, regularly US$16.00 |
| Saily | US$9.99 5GB / 30 days | US$15.99 10GB / 30 days |
| Airalo | US$9.00 5GB / 7 days | US$15.00 10GB / 7 days |
| aloSIM | US$10.00 5GB / 30 days | US$16.00 10GB / 30 days |
For 5GB, the lower total is US$9.00 with Nomad eSIM or Airalo. For 10GB, Ubigi is US$3.00 below Nomad eSIM’s current local sale price. Nomad’s 30-day validity becomes more useful if your dates may change; it does not increase the amount of data you receive.
Seven Singapore eSIM Providers Compared
Nomad eSIM: A Good Fit for Short Stays and Malaysia Trips
Nomad eSIM’s SG–MY–TH plan combines a useful price with coverage in all three countries. The 3GB and 5GB packages cost US$6.00 and US$9.00, both valid for 30 days. These fixed-data packages list Singtel 5G in Singapore and allow hotspot use.
The plan starts when it connects to a supported network, or automatically after 60 days if unused. A single data allowance covers the whole route, so crossing into Malaysia does not create a new 3GB or 5GB balance. Choose the regional package deliberately: the cheaper local 10GB sale offer in the table covers Singapore only.
Choose it for: a 3GB city break, a flexible 5GB week, or onward travel to Malaysia. Ubigi has the lower base price for 1GB and 10GB over seven days.

Ubigi: Low-Cost Data for a Stopover or a Week
Ubigi stands out at two useful sizes: 1GB / 7 days for US$3.00 and 10GB / 7 days for US$11.00. Its 3GB / 15-day option also matches Nomad eSIM’s US$6.00 price if Singapore is your only destination.
The selected Singapore offers list StarHub and SIMBA. Smartstart begins the package when you arrive in the destination, and data sharing is allowed. Ubigi also supports topping up through its app without a remaining data balance or Wi-Fi connection.
Choose it for: the lowest 1GB and 10GB purchase prices in this fixed-data comparison, including occasional laptop sharing. The seven-day package leaves less room for an extended trip than a 30-day alternative. It provides data, not a Singapore calling number.
Saily: An Alternative with Built-In Security Features
Saily’s Singapore plans include 1GB / 7 days for US$3.99, 3GB / 30 days for US$6.99 and 5GB / 30 days for US$9.99. Its virtual location, ad blocker and web protection are useful differentiators if you want those features alongside mobile data.
The fixed-data plans allow hotspot use from your purchased balance, without a separate daily sharing allowance. The Singapore destination page does not name a specific local network, so network preference is not a reason to choose it over a provider that identifies its partners.
Choose it for: its app and security features. The Singapore plan covers Singapore only; a Malaysia leg needs a suitable regional plan or a separate purchase. Ordinary voice calls and SMS are not included.

Airalo: Short Packages with Named Network Partners
Airalo’s ConnectLah packages list Singtel 5G and M1 LTE. Its 5GB / 7-day package costs US$9.00, matching the base price of Nomad eSIM’s regional 5GB offer.
Pay attention to the selected duration. The US$6.50 3GB plan lasts three days; 3GB for seven days costs US$7.00. The selected packages start on first connection to a supported network and are data-only. Airalo permits tethering where the device and network support it; hotspot settings may need the plan’s APN.
Choose it for: a 5GB week or an existing Airalo setup. Its local Singapore package does not cover an onward Malaysia trip.
aloSIM: StarHub Data with an Optional App-Based Number
aloSIM’s Singapore plans use StarHub LTE/5G. The 3GB / 30-day package costs US$7.00, and 5GB / 30 days costs US$10.00. Hotspot use is supported.
A qualifying purchase can include a Hushed phone-number offer. This is a separate app-based US or Canadian number, not a Singapore +65 number attached to the eSIM. The Hushed promotion includes US$3 of credit, with validity tied to the data plan; it is not unlimited calling.
Choose it for: StarHub data and the Hushed offer if that number is useful to you. If you only want mobile data, several alternatives in the tables cost less.
Holafly: Unlimited Phone Data with a Daily Hotspot Limit
Holafly sells Singapore data by trip length and lists Singtel as its network. Its unlimited allowance is subject to an operator fair-use policy, including possible temporary speed reductions. Hotspot sharing is limited to 1GB per day.
The table below is separate because this is a day-based unlimited product, rather than a fixed 1GB, 3GB or 10GB pool.
Holafly Singapore — total price in USD
| Purchased duration | Data and sharing | Total price (USD) |
|---|---|---|
| 1 day | Unlimited phone data 1GB/day hotspot | US$3.90 |
| 3 days | Unlimited phone data 1GB/day hotspot | US$11.90 |
| 7 days | Unlimited phone data 1GB/day hotspot | US$27.50 |
Choose it for: phone use that would quickly exhaust a small fixed package. It is less suitable for long laptop sessions or sharing with several travellers. Holafly counts each plan day as 24 hours from activation at the destination. Its Singapore plan details explain the hotspot and fair-use conditions.
Singtel hi! Tourist: A Large Allowance with Different Activation Rules
Singtel hi! Tourist deserves a look if you want substantially more phone data. Its current direct offer includes 500GB across Singapore, Malaysia, Indonesia, Thailand and Hong Kong. Prices below are in Singapore dollars and have not been converted into USD.
Singtel hi! Tourist — total price in SGD
| Tourist plan | Data and validity | Total price (SGD) |
|---|---|---|
| Singtel hi! Tourist 7-day | 500GB across SG, MY, ID, TH and HK 7 days from purchase | S$10.00 |
| Singtel hi! Tourist 30-day | 500GB across SG, MY, ID, TH and HK 30 days from purchase Additional roaming allowances | S$15.00 |
Purchase timing matters: validity starts when you buy. Singtel’s tourist-plan terms specify expiry at 23:59 on the expiry date. Buy close to arrival and check the displayed expiry against your departure time.
Expect data-only service initially. The current tourist page says calls and SMS can be enabled at a hi! retailer in Singapore with passport verification. Do not rely on a working local voice number or verification texts straight after installing the eSIM.
Choose it for: a large phone-data allowance when these purchase and registration conditions fit your trip. We could not confirm a separate tethering policy for these exact tourist offers, so a plan with documented sharing terms is the clearer choice if laptop use is essential.
Can You Use One eSIM for Singapore and Malaysia?
Yes, if you choose a package that explicitly covers both countries. For a route with seven days in Singapore followed by seven days in Malaysia, Nomad eSIM SG–MY–TH 10GB / 30 days costs US$15.00 for the whole route. That is a shared 10GB balance, not 10GB per country. Its selected regional packages list Singtel in Singapore and Maxis and DiGi in Malaysia.
The regional plan costs US$1.00 more than Nomad eSIM’s current Singapore-only 10GB sale plan. That extra dollar changes the coverage; the local sale plan cannot follow you into Malaysia. The US$6.00 regional 3GB package can suit a much lighter two-country trip.
Singtel’s 30-day tourist offer also includes Malaysia. Its purchase-started validity remains important if Singapore is only one part of a longer journey.
For the next leg, see our Malaysia eSIM comparison. If the route includes more countries, use the Southeast Asia eSIM guide to compare regional coverage before buying.
How Much Data Do You Need, and Can You Share It?
Use the comparison amounts as planning budgets, not guaranteed consumption. A 1GB package is a starting point for a day of maps, messages and occasional ride bookings. Three gigabytes gives a short city break more room, while 5–10GB is a practical range to compare for a week with regular Wi-Fi access.
Video streaming, cloud photo backups, app updates and laptop downloads can change that budget quickly. Download offline maps before leaving and move large transfers to Wi-Fi. Our travel eSIM data guide helps turn your actual usage into a package size.
For laptop sharing, start with the documented fixed-data options: Nomad eSIM, Ubigi, Saily, Airalo and aloSIM. Hotspot usage consumes the same purchased balance. Holafly has a separate 1GB daily sharing limit, so its unlimited phone allowance is not a substitute for an unrestricted laptop connection.
Named networks are useful for understanding the offer, but they do not establish which eSIM will be fastest in your hotel, on a train or inside a building. This guide does not rank real-world network performance.
How to Install and Activate Your Singapore eSIM
- Check the exact phone model. It must support eSIM in its regional version and be carrier-unlocked. A provider’s compatibility check is more useful than assuming every version of a model works.
- Buy the correct destination and duration. Confirm Singapore-only versus regional coverage, the data balance and what starts the validity clock. Buy Singtel’s tourist offer close to use.
- Install on a stable internet connection. Follow the provider’s app, QR-code or manual setup instructions. If the QR code is on the same phone, use a supported direct-install option or display it on another screen.
- Choose the travel eSIM for mobile data on arrival. Enable data roaming on that line if the provider instructs you to, and follow its APN settings. Keep home-line data roaming and automatic data switching off if you want to avoid unintended home-carrier data charges.
- Confirm the connection. Turn off Wi-Fi briefly and load a map or webpage. If data does not work, check the selected data line, remaining allowance and provider instructions before deleting the eSIM.
You can often keep your normal line available alongside the travel eSIM. Our guide to using an eSIM and physical SIM together explains the settings and device limitations.
Final Verdict
Start with Ubigi for a 1GB stopover or 10GB week, and Nomad eSIM SG–MY–TH for a 3GB break, a flexible 5GB package or onward travel to Malaysia. These choices follow the full package prices and trip coverage.
Consider Singtel hi! Tourist when a large phone-data allowance outweighs its purchase-started validity and registration steps. Holafly suits day-based unlimited phone use if its hotspot and fair-use limits fit your needs. Saily, Airalo and aloSIM offer useful alternatives for security features, named network partners or an app-based phone number.

Frequently Asked Questions
Does a Singapore travel eSIM give me a local phone number?
The fixed-data travel plans compared here do not include a Singapore voice number. aloSIM’s Hushed offer uses a separate US or Canadian app-based number. Singtel requires additional in-person steps for calls and SMS. If native calling is essential, compare the exact service in our guide to eSIMs with a phone number.
Can I keep receiving messages on my usual number?
Messaging apps can use the travel eSIM’s internet connection while retaining your existing account. Ordinary SMS sent to your home number still depend on your home SIM or eSIM being active and your carrier supporting service abroad. Check that carrier’s roaming terms; a data-only travel plan does not receive those SMS for you.
What if my phone is locked to my home carrier?
Ask the carrier about unlocking before buying a travel eSIM. Installing a new profile does not remove a carrier lock. Also check your exact regional phone model, because eSIM support can differ between versions.
Is 5G necessary for a short Singapore visit?
Maps, messaging and ride bookings do not require a 5G plan. Prioritise a compatible device, sufficient data, valid trip dates and suitable sharing terms. A 5G label alone does not guarantee a particular speed or indoor signal.
