I tested Saily in Singapore in August 2026 and documented two mobile-data speed tests. Both tests used 5G and reached more than 100 Mbps in download speed.

Across the two measurements, I recorded an average download speed of 119.84 Mbps, an average upload speed of 27.52 Mbps, and an average latency of 272.5 ms.

My two tests reached 103.03 Mbps in Marina Bay and 136.65 Mbps in Loyang, close to Singapore Changi Airport.

Best eSIM for Singapore: Based on my own testing, Saily is my overall pick for most travelers. The download performance was strong in both locations, although latency was clearly the main weakness in my test results.

For normal travel use such as Google Maps, Grab, WhatsApp, browsing, streaming, cloud apps, and bookings, the connection was easily fast enough.

However, my dataset is small. Two measurements cannot prove that Saily delivers the same performance everywhere in Singapore.

Saily eSIM for Singapore – tested with real 5G speed measurements in Marina Bay and Loyang.

Why I recommend Saily as an eSIM for Singapore

I recommend Saily for Singapore because I actually used and tested the eSIM there instead of relying entirely on provider specifications.

Both of my mobile tests exceeded 100 Mbps, despite being recorded on different days and in different parts of Singapore.

That was more than enough for everything I normally need while traveling:

• Google Maps

• Grab

• WhatsApp

• video calls

• social media

• streaming

• cloud applications

• restaurant research

• hotel and attraction bookings

• laptop hotspot use

The main drawback in my results was not download speed but latency.

I measured 188 ms in Marina Bay and 357 ms in Loyang.

For Maps, messaging, browsing, and streaming, that would not stop me from using the service.

For latency-sensitive tasks such as competitive gaming, remote desktop, SSH, or some real-time video-call scenarios, I would consider those values a meaningful weakness.

For more of my experiences with the provider across different countries, see my full Saily eSIM review.

How fast was the Saily eSIM in Singapore?

Across my two documented Saily mobile-data tests in Singapore, the average download speed was 119.84 Mbps.

Singapore field testing	Result
Documented Saily mobile tests	2
Average download	119.84 Mbps
Average upload	27.52 Mbps
Average latency	272.5 ms
Fastest download	136.65 Mbps
Slowest download	103.03 Mbps
Connection type	2× 5G
Test period	August 21–22, 2026

These were my two mobile measurements:

Date	Location	Download	Upload	Latency	Connection
Aug. 21, 2026	Marina Bay	103.03 Mbps	30.16 Mbps	188 ms	5G
Aug. 22, 2026	Loyang	136.65 Mbps	24.88 Mbps	357 ms	5G

The download results were relatively consistent.

The more noticeable variation was latency.

A high-latency result can be affected by routing, network congestion, roaming architecture, or other network conditions. I cannot determine the exact cause from the Speedtest results alone.

---

My fastest Saily test in Singapore: 136.65 Mbps

My fastest Saily speed test in Singapore reached 136.65 Mbps in Loyang on August 22, 2026.

The test measured:

• 136.65 Mbps download

• 24.88 Mbps upload

• 357 ms latency

• 5G connection

Loyang is in eastern Singapore and relatively close to Changi Airport.

At more than 136 Mbps, the connection had enough raw bandwidth for streaming, large downloads, cloud applications, video uploads, and laptop tethering.

The 357 ms latency, however, was high.

I would therefore describe this result as strong for bandwidth but weak for latency-sensitive applications.

I would also not treat this one measurement as representative of the entire Changi Airport area or Singapore as a whole.

---

My Saily test in Marina Bay: 103.03 Mbps

My second measurement was recorded in Marina Bay on August 21, 2026.

It reached:

• 103.03 Mbps download

• 30.16 Mbps upload

• 188 ms latency

• 5G connection

The download result was lower than in Loyang but still easily sufficient for normal travel use.

The lower latency of 188 ms was also better than my Loyang result, although still relatively high compared with a typical direct local mobile connection.

---

Does Saily have 5G in Singapore?

Both of my documented Saily mobile tests in Singapore connected over 5G.

That included:

• Marina Bay: 103.03 Mbps

• Loyang: 136.65 Mbps

This proves that I was able to use Saily over 5G at those two locations.

It does not prove that 5G is available with Saily everywhere in Singapore.

Mobile connectivity can change depending on:

• exact location

• buildings

• signal strength

• local network availability

• network congestion

• roaming agreements

• device

• automatic network selection

---

What network does Saily use in Singapore?

I cannot reliably identify the underlying Singapore mobile network from my Speedtest server names.

One of my tests used a server operated by PT. Indosat Tbk, while the other used PT. Mora Telematika Indonesia.

Those server names describe test infrastructure or routing.

They do not prove that my phone was connected to an Indonesian mobile network while I was physically in Singapore.

This distinction matters with travel eSIMs because the local radio network, roaming partner, internet routing, and Speedtest server can involve different companies.

I therefore treat Speedtest server names only as test infrastructure.

What my measurements actually prove is much simpler:

Saily connected over 5G at both of my test locations in Singapore.

Saily vs. Airalo vs. Holafly for Singapore

For my own Singapore trip, I would choose Saily because it is the provider I personally tested there.

Provider	Best for	My assessment
Saily	Travelers who want the option I personally tested in Singapore	My overall pick
Airalo	Travelers comparing different fixed-data and unlimited plans	Strong alternative
Holafly	Travelers focused primarily on unlimited data	Good unlimited-focused alternative
Local Singapore SIM/eSIM	Travelers who need a local +65 number	Better for local mobile services

Saily currently offers both fixed-data and unlimited options for Singapore.

Airalo also offers a range of Singapore eSIM packages, while Holafly remains an option for travelers who primarily want an unlimited-data product.

However, this is important:

I did not test Airalo or Holafly in Singapore.

This comparison is therefore based on current plan features rather than equivalent real-world field testing.

I do not claim that Saily is objectively faster than either competitor.

What I can say is that Saily is the Singapore eSIM I can evaluate using my own measurements.

For broader provider comparisons, see my Saily vs. Airalo comparison and Holafly vs. Saily comparison.

---

Which eSIM would I choose for Singapore?

For a normal Singapore trip, I would personally choose Saily again.

My decision would look like this:

• Saily: if I want the option supported by my own Singapore test data

• Airalo: if its current package size or price better fits my trip

• Holafly: if its unlimited-data offer better matches my usage

• Local Singapore SIM/eSIM: if I specifically need a local +65 number

For a typical city trip, I would not automatically buy unlimited data.

Maps, Grab, WhatsApp, bookings, restaurant research, and normal web browsing use relatively little data.

Unlimited data becomes more useful if I plan to:

• stream video heavily

• upload large files

• work extensively from my phone

• tether a laptop for long periods

• use mobile data as my primary internet connection

For more detail, see my Saily eSIM plans guide.

---

Does Saily include a Singapore phone number?

A normal Saily Singapore data plan does not include a local Singapore +65 phone number.

Saily also offers a separate phone-number feature for calls and SMS.

However, this provides a US +1 number, not a local Singapore number.

If I needed a local +65 number for calls, SMS verification, registrations, or other local services, I would consider a local Singapore SIM or eSIM instead.

For WhatsApp, FaceTime, Signal, Telegram, Google Maps, Grab, and other internet-based apps, a local phone number is normally not necessary.

---

Singapore eSIM or Asia regional eSIM?

For a Singapore-only trip, I would normally choose a Singapore plan. For a multi-country trip through Asia, I would also compare a regional eSIM.

That becomes useful for trips combining Singapore with destinations such as:

• Malaysia

• Indonesia

• Thailand

• Vietnam

• Japan

The advantage is convenience.

Instead of buying and managing a separate eSIM for every country, one regional eSIM can remain installed while traveling between destinations.

A regional package is not automatically cheaper, though.

I would compare the current price, data allowance, validity period, and country coverage before buying.

---

Is a Singapore eSIM better than international roaming?

For many travelers, I think so.

If I were traveling from the United States, Canada, Europe, Australia, or another country, I would compare my carrier's Singapore roaming prices with a travel eSIM before departure.

A travel eSIM also lets me keep my normal SIM active for my regular phone number while routing mobile data through the travel eSIM.

On a compatible dual-SIM phone, I would normally:

1. keep my normal SIM enabled,

2. select Saily as the mobile-data line,

3. disable data roaming on my home SIM if necessary,

4. use Saily for mobile internet.

---

How I would set up a Singapore eSIM

I prefer installing my travel eSIM before departure while I still have reliable Wi-Fi.

My normal setup process is:

1. Install the Saily eSIM before the trip.

2. Purchase the Singapore or regional data plan.

3. Select Saily as the mobile-data line after arrival.

4. Enable data roaming for the Saily profile.

5. Leave automatic network selection enabled initially.

6. Only change network settings manually if there is a connection problem.

If Saily does not connect after arrival, I would first:

• turn airplane mode on and off

• check that data roaming is enabled for Saily

• verify that Saily is selected for mobile data

• disable and re-enable mobile data

• restart the phone

For step-by-step instructions, see my Saily setup guide for iPhone and Saily Android setup guide.

---

Who should not choose Saily for Singapore?

I would not recommend Saily automatically to every traveler.

I would consider another option if I:

• specifically need a local Singapore +65 phone number

• need a particular Singapore mobile network

• find a better package from another provider for my exact trip

• plan to live in Singapore long term

• need consistently low latency for gaming, remote desktop, or other real-time applications

• want a local mobile subscription rather than a travel eSIM

For a normal Singapore trip involving Maps, Grab, WhatsApp, browsing, social media, streaming, and bookings, Saily worked well in my tests.

Frequently asked questions

What is the best eSIM for Singapore?

My pick for most travelers is Saily because it is the Singapore eSIM I have personally tested.

My two documented 5G measurements reached 103.03 and 136.65 Mbps.

Airalo and Holafly are still worth comparing if their current plans better match your data requirements.

Is Saily good in Singapore?

Based on my own tests, yes overall.

Both of my mobile measurements exceeded 100 Mbps and used 5G.

The main weakness was latency, which reached 188 ms and 357 ms.

How fast is Saily in Singapore?

My two Saily tests reached:

• 103.03 Mbps in Marina Bay

• 136.65 Mbps in Loyang

The average was 119.84 Mbps.

These results only represent my test locations and dates and should not be interpreted as guaranteed speeds across Singapore.

Does Saily support 5G in Singapore?

Yes at both locations where I tested it.

Both my Marina Bay and Loyang measurements used 5G.

Does Saily work near Changi Airport?

My Loyang test was recorded in eastern Singapore relatively close to Changi Airport and reached 136.65 Mbps over 5G.

I did not conduct the measurement inside an airport terminal, so I would not claim that it represents performance throughout Changi Airport itself.

Does Saily provide a Singapore phone number?

No local +65 number is included with the standard Singapore data plan.

Saily separately offers a US +1 number for calls and SMS.

Which is better for Singapore: Saily, Airalo, or Holafly?

For my own trip, I would choose Saily because it is the provider I personally tested in Singapore.

I did not test Airalo or Holafly under equivalent conditions, so I cannot make a valid speed comparison between the three providers.

About This Test & Methodology

I personally conducted the two cellular Saily measurements used in this review for TechNovice. Tester: Svenja Eichenberger.

Primary data source: my own mobile speed tests recorded in Singapore using Speedtest by Ookla.

I conducted the two Saily cellular measurements in Marina Bay and Loyang between August 21 and August 22, 2026:

• Marina Bay: 103.03 Mbps download, 30.16 Mbps upload, 188 ms latency, 5G

• Loyang: 136.65 Mbps download, 24.88 Mbps upload, 357 ms latency, 5G

Across the two cellular Saily tests, I measured:

• Average download: 119.84 Mbps

• Average upload: 27.52 Mbps

• Average latency: 272.5 ms

• Download range: 103.03–136.65 Mbps

• Connection types: two 5G tests

With only two measurements, I use these figures as a compact summary of my own test results rather than as evidence of typical performance across Singapore.

I also recorded a separate Wi-Fi measurement in Outram Park on August 20, 2026. Because it did not use the Saily cellular connection, I do not count it as part of this Singapore eSIM test or include it in any performance statistics.

I separate my own field measurements from provider information. I personally measured every Saily speed result described in this article, while network support, plan capabilities, unlimited-data options, phone-number features, and other provider details were researched separately.

I also treat Speedtest server names only as test infrastructure and never as proof of the underlying mobile carrier.

This is particularly relevant in Singapore because my Speedtest results used servers associated with Indonesian companies. That does not mean my phone was connected to an Indonesian cellular network. Server selection can reflect routing and test infrastructure rather than the cellular network serving the device.

Finally, these results reflect my test dates, locations, device conditions, routing, and network environment.

Mobile performance can change with:

• network congestion

• building density

• signal strength

• roaming arrangements

• routing

• device capability

• local network availability

• exact location

With only two cellular measurements, I do not claim that my results represent Saily performance across all of Singapore.

My recommendation is therefore based on my documented real-world testing in Singapore, not on a claim that every traveler will receive identical performance.

1. Select Saily as the mobile-data line after arrival.

2. Enable data roaming for the Saily profile.

3. Leave automatic network selection enabled initially.

4. Only change network settings manually if there is a connection problem.

If Saily does not connect after arrival, I would first:

• turn airplane mode on and off

• check that data roaming is enabled for Saily

• verify that Saily is selected for mobile data

• disable and re-enable mobile data

• restart the phone

I would only start changing more advanced network settings after those basic steps.
