Singapore might be one of the easiest Asian countries without a visa hassles for many travelers, but staying connected once you land is a whole other game.
As someone who’s worked remotely across Southeast Asia, I’ve tried more eSIMs than bubble tea flavors and trust me, not all of them deliver what they promise.
If you’re headed to the Lion City and torn between Airalo and Saily, you’re in the right place.
I’ll walk you through both, but spoiler alert: Airalo’s Singapore eSIM already has a strong edge with its flexible plans, budget-friendly pricing, and solid network performance that’s kept me online from Changi Airport to café-hopping in Tiong Bahru.
Variety of Plans
Airalo
Airalo knows how to roll out the red carpet for travelers with diverse data habits. Whether you’re that person who just needs enough data to check Google Maps and post the occasional foodie pic, or you’re planning to work remotely from every hipster café in Tiong Bahru, Airalo’s got your back.
For Singapore, they offer a flexible spread: plans start at a handy 1GB for 7 days and scale up all the way to a robust 20GB for 30 days.
All plans tap into Singtel’s powerhouse network, so you’re pretty much guaranteed speedy and stable data wherever you wander.
Topping up or switching plans is ridiculously easy via the Airalo app, so you can adapt on the fly if your “quick getaway” turns into a full-on Singaporean staycation.
For travelers who don’t want to overthink it but also hate surprises, Airalo keeps things smooth, simple, and customizable.
Saily
Saily doesn’t disappoint when it comes to affordability either. Their plans start at around $4.90 USD for 1GB/7 days, just a hair above Airalo’s base price, but still way cheaper than buying a physical SIM at the airport.
Bigger data packages, such as 10GB and unlimited options, are also competitively priced, and Saily sometimes runs promotions that knock a few bucks off for new users.
Where Saily shines is in flexibility: their app lets you fine-tune your data and validity before purchase, so you only pay for what you need. Reddit travelers highlight the app’s smooth payment process and no-nonsense billing—no unpleasant surprises on your statement.
While both are wallet-friendly, Airalo takes the slight win for consistently lower entry-level prices and its ease of “set it and forget it” top-ups. But Saily fans will love the ability to tweak and save for custom needs.
Price and Affordability
Airalo’s Per-GB Pricing Advantage
If you’re all about saving for that next chili crab feast, Airalo’s pricing will make you smile. Their Singapore eSIM plans start at a wallet-friendly $4.50 USD for 1GB (valid for 7 days).
This is one of the lowest entry points you’ll find. Bigger data packages (think 3GB, 5GB, 10GB, and 20GB) are also priced to please, with 20GB for just $26 USD.
The more you buy, the less you pay per gig, so you can stream, scroll, and story to your heart’s content without draining your travel budget.
Airalo doesn’t do hidden fees, annoying surcharges, or sneaky small print—what you see is what you pay. Topping up is instant, plan switching is painless, and their app keeps your spending super transparent.
Plus, they sometimes toss in referral credits and new user promos, which is basically their way of saying “welcome to the club.”
Saily
Saily also brings substantial value to the table, with plans starting at $4.90 USD for 1GB over 7 days—not far off from Airalo, but slightly pricier at the entry level. Saily’s mid- and large-size plans are close in price to Airalo’s, and if you’re a data power user, Saily’s unlimited option (around $40 USD for 30 days) might catch your eye.
Where Saily stands out is in flexibility: their app lets you mix and match data amounts and validities before checkout, so you’re never stuck paying for more than you need. And, according to Reddit travelers, they often drop promo codes or in-app discounts, so savvy shoppers can shave a little off the sticker price.
Bottom line? Saily is a great choice if you prefer ultra-customizable plans and don’t mind searching for occasional promo codes. However, if you’re looking for the lowest starting price, effortless top-ups, and a proven track record of value for money, Airalo has the edge.
Network Coverage – Who Keeps You Connected?
Airalo’s Local Partnerships
When I touched down in Singapore, I activated my Airalo eSIM within minutes and was cruising through city maps and WhatsApp like a local.
Airalo partners with top-tier local carriers like Singtel and StarHub, which meant I had dependable 4G LTE access almost everywhere—from the shophouses of Katong to the sleek towers of Marina Bay.
Even during peak hours, I rarely noticed a dip in performance. That’s saying something in a city that runs on tech and efficiency.
Now, I won’t say it’s flawless. The signal occasionally dropped to 3G while I was riding the MRT or navigating underground walkways, but it snapped back quickly. I still booked rides, sent updates to clients, and checked real-time weather without stress.
For a digital nomad who depends on a stable connection to work and wander, Airalo’s local tie-ins gave me the kind of coverage that felt like a safety net.
Saily’s Performance in the Field
Saily also hooks into major Singaporean networks—most likely the same ones Airalo uses, though they’re a bit more cryptic about the specifics.
In day-to-day use, it held up well. I tested it while coworking in Chinatown, wandering through Gardens by the Bay, and catching golden hour in Sentosa. Streaming short videos worked fine, and voice calls on WhatsApp were clear with just a beat of latency now and then.
That said, I did run into occasional hiccups during high-traffic moments, like lunchtime in Orchard Road or evening surges near Clarke Quay. The slowdown wasn’t dramatic, but it was enough to make me notice.
For someone who relies on timing and quick uploads—hello, last-minute client deliverables—it added just a touch of friction. It’s solid, no doubt. But when you’re juggling remote work and sightseeing, even small network delays can trip you up.
Device Compatibility – Will It Work on Your Phone?
Airalo’s Broad Compatibility
One of the best things about Airalo is that it just works. I’ve used it across a range of devices over the years—from my iPhone 14 Pro to Samsung Galaxy.
If your phone is unlocked and supports eSIM, chances are high that Airalo’s ready to roll. It plays nice with iOS, Android, and even tablets, making it an easy fit whether you’re team Apple or Android.
What’s more, their app is intuitive and available on both major platforms. Installation is quick, and the in-app prompts guide you like a GPS with zero attitude. Whether you’re new to eSIMs or a seasoned pro, Airalo doesn’t throw curveballs during setup.
You tap, scan, and boom—you’re connected. It’s the kind of no-fuss experience that digital nomads like me really appreciate, especially when bouncing between countries.
Saily’s Device Support
Saily covers a broad range of eSIM-capable devices, and for most people, that’s enough. The testing process was smooth, and I appreciated how beginner-friendly it felt—especially for travelers who might not be super tech-savvy. The step-by-step instructions don’t assume you’re an engineer, and that’s a win.
That said, their support site doesn’t go into as much detail when it comes to lesser-known or older Android models. If you’re using a newer flagship phone, you’ll be fine.
But if you’ve got a quirky device or a budget Android that supports eSIM, you might have to do a little extra digging. It’s not a dealbreaker, just something to keep in mind if you prefer full transparency up front.
Security and Privacy – Trust Is Everything
Airalo’s Transparent Data Practices
When it comes to privacy, Airalo doesn’t make you dig through a maze of fine print. Their privacy policy is clear, accessible, and free of the usual legal mumbo jumbo.
As someone who works online and handles client data while traveling, I need to know my info isn’t being passed around like snacks at a hostel party—and with Airalo, I feel confident that it’s not.
They’ve also built a strong reputation within the digital nomad and remote work community, and it shows. I’ve seen them recommended time and again in trusted circles, which tells me I’m not alone in valuing their transparency.
You shouldn’t have to trade your personal data just to use mobile internet—and with Airalo, you don’t.
Saily’s Security Policies
Here’s where Saily still has some growing up to do. Their site doesn’t offer much detail on how user data is handled or protected. I looked around for a solid privacy policy or specifics on data sharing practices, but there wasn’t much to work with.
For a provider that’s asking for your device info and payment details, that lack of clarity is a bit of a red flag. That’s not to say Saily is doing anything wrong—it’s more that they haven’t earned the same level of trust yet.
If they want to compete with big names like Airalo, they’ll need to step up their transparency game. Until then, I’d recommend using them cautiously if data privacy is high on your list.
