HelloRoam -- Highest Composite Score
HelloRoam scores 4.64/5 overall on our 2026 rubric, with App 5.0/5 and Support 5.0/5. The $3.50/GB floor beats Airalo's and Saily's per-GB rates while staying close to Nomad's Southeast Asia-optimized pricing, unlimited starts from $5, and 204+ carrier partnerships connect to whichever of Singtel, StarHub, or M1 performs best in a given pocket of the island. The iOS and Android app plus live chat and WhatsApp matter more for setup than for coverage here, since Singapore's near-identical carrier performance already narrows most provider differences to price and app polish.
Dimension scores, 0-5 on our rubric
Pros
- 186 countries with 204+ carrier partnerships for reliable local routing
- Fixed plans from $3.50/GB across popular destinations
- Unlimited plans from $5 for short stays, scaling by duration
- iOS and Android app with in-app top-up, add-destination, and usage alerts
- Live chat, WhatsApp, and email support, including real-time channels
- 31+ local currencies supported at checkout
- 63-language interface for non-English travelers
Cons
- Newer brand (launched August 2025) with shorter track record
- 186 countries, behind Airalo's 200+ catalogue
Airalo -- Widest Coverage Catalogue
Airalo's Coverage score (4.9/5 on the rubric, 200+ countries) carries more weight on a multi-country Southeast Asia itinerary than on a Singapore-only trip, since Singtel, StarHub, and M1 all deliver near-identical 5G performance across the island regardless of provider. At $4.50/GB, Airalo's floor runs above HelloRoam's $3.50/GB and Nomad's $3.00/GB, a real difference on a typical 4-day Singapore trip where total data needs stay modest.
Dimension scores, 0-5 on our rubric
Pros
- 200+ countries with the widest coverage breadth in the market
- Regional multi-country bundles (Asialink, Eurolink, Discover Global)
- Automatic in-app install with real-time data tracking and hourly runtime estimates
- Airmoney cashback rewards (5-10% depending on loyalty tier)
- Established brand since 2019 with proven reliability
Cons
- Per-GB pricing higher than budget alternatives
- Unlimited plans available in select markets only, not all 200+ destinations
- No live chat or WhatsApp channel: support runs on email and in-app messaging
Nomad -- Best Budget Per-GB Rate
Nomad's Pricing score (4.8/5 on the rubric, the highest of the five) reflects rates built around Southeast and East Asia, and that regional discount extends to Singapore, pushing its $3.00/GB floor below HelloRoam's $3.50/GB and Airalo's $4.50/GB. Nomad's 200-country footprint matches Saily's and its Support score (3.5/5 on our rubric) is the lowest, a smaller trade-off on a short 4-day Singapore trip than on a longer, more complex itinerary.
Dimension scores, 0-5 on our rubric
Pros
- Competitive pricing starting from $3.00/GB in Southeast Asia
- Simple, fast checkout with no account required in many cases
- Lowest per-GB rates for Thailand, Vietnam, South Korea, and Japan
- Plans start at a low entry price for short trips
Cons
- Email-only support with no live chat, WhatsApp, or phone channel
- Basic app compared to Airalo and Saily
- 200 countries, behind only Airalo among the five providers
- Limited plan variety in some countries
Holafly -- Best Unlimited Daily Rate
Holafly's $2.99/day unlimited rate suits the rare case of tethering a laptop or streaming heavily during a short Singapore stay, since the island's 2.0GB average daily use sits well under most fixed-plan caps already. HelloRoam also sells unlimited from $5. Holafly's 160-country footprint and 4.5/5 on the rubric Coverage score still trail Airalo's 200+, though Singapore's near-identical 5G performance across carriers narrows that gap to a non-factor here.
Dimension scores, 0-5 on our rubric
Pros
- Unlimited daily data from $2.99/day with no data caps
- 160+ countries covered including all major destinations
- Simple per-day pricing: know exactly what you pay before you leave
- 180-day refund policy on unused plans
- 24/7 chat support alongside email
Cons
- Speeds reduce after the daily fair use threshold on most plans
- Hotspot tethering limited to 1 GB/day on select destinations
- Not cost-effective for light data users (under 3 GB/trip)
- Fewer countries than Airalo
Saily -- Best for Privacy
Saily's App score (4.5/5 on our 2026 rubric) and clean one-tap interface stand out on a short 4-day Singapore trip where setup speed matters more than long-term plan management, and its $3.99/GB rate still undercuts Airalo's $4.50/GB floor. Saily's bundled NordVPN carries less weight in Singapore than in VPN-restricted markets, since VPN use here is already legal and unrestricted.
Dimension scores, 0-5 on our rubric
Pros
- Backed by NordVPN parent company Nord Security with proven privacy infrastructure
- Integrated VPN protection included on every plan at no extra cost
- Clean, privacy-focused app with VPN toggle inside the eSIM interface
- 200 countries with strong European coverage
- 30-day refund policy
Cons
- Email-only support with no live chat or WhatsApp for urgent help
- Fixed data plans only; no unlimited daily tier
- 200 countries, just behind Airalo's 200-plus

FAQ
Singapore eSIM questions, answered
Which eSIM provider has the best coverage in Singapore?
Which eSIM provider has the best coverage in Singapore?
HelloRoam leads the 2026 composite at 4.64/5 in our comparison matrix. All five providers route through Singtel, StarHub, or M1, and all three run the same island-wide standalone 5G, holding steady from the Central Business District to Sentosa. Coverage ties across providers in Singapore's compact geography, so Airalo's wider 200+ country footprint matters more for itineraries continuing beyond Singapore than for the island alone.
How do eSIM speeds compare in Singapore?
How do eSIM speeds compare in Singapore?
Singapore's standalone 5G network is the most complete rollout in this comparison series, holding steady across the entire island, including Sentosa and East Coast Park. Because Singtel, StarHub, and M1 perform near-identically here, speed does not separate the five eSIM providers in Singapore the way it does in larger or less-developed markets.
Which eSIM has the cheapest per-GB rate for Singapore?
Which eSIM has the cheapest per-GB rate for Singapore?
Nomad posts the highest Pricing score (4.8/5 on our rubric) at $3.00/GB, with Southeast Asia-optimized rates that extend to Singapore. HelloRoam's $3.50/GB floor and Holafly's $2.99/day unlimited tier both undercut Airalo's $4.50/GB and Saily's $3.99/GB. Singapore's market-wide floor checks in at $0.74/GB, a premium versus Thailand or Vietnam but roughly 70% cheaper than carrier roaming from the US, UK, or Australia.
Do all eSIM providers perform the same in Singapore?
Do all eSIM providers perform the same in Singapore?
On coverage and speed, yes. Singtel, StarHub, and M1 deliver near-identical 5G performance across the island, so the five eSIM providers compared here tie on those two dimensions. HelloRoam still leads the 2026 composite at 4.64/5 on our 2026 rubric. The remaining differences show up in Pricing (Nomad highest at 4.8/5), App quality (HelloRoam highest at 5.0/5 in our comparison matrix), and Support, where Nomad's email-only model scores lowest at 3.5/5.
Is an eSIM cheaper than a local SIM in Singapore?
Is an eSIM cheaper than a local SIM in Singapore?
Local prepaid SIMs cost $10 to $20 for 30GB to 100GB over 14 to 28 days, more data than most travelers use on Singapore's average 4-day trip. An e SIM skips the 5 to 10 minute counter wait at Changi, and Singapore's $0.74/GB market floor sits well under the $4.50/GB ceiling of the priciest provider compared here.
Which eSIM app works best for a short Singapore trip?
Which eSIM app works best for a short Singapore trip?
HelloRoam leads the 2026 composite at 4.64/5 in our comparison matrix and posts the highest App score at 5.0/5, with an iOS and Android app plus in-app top-up useful on a 4-day trip. Airalo's App score follows at 4.7/5 on the rubric, with real-time tracking against Singapore's 2GB average daily use. Saily's App score is 4.5/5 on our 2026 rubric, with one-tap setup that suits a quick layover.
Should I get an unlimited or fixed eSIM plan for Singapore?
Should I get an unlimited or fixed eSIM plan for Singapore?
A fixed plan fits most Singapore trips, since the average traveler uses 2GB per day across a 4-day stay, well inside a 10GB plan's range. Holafly's $2.99/day unlimited tier and HelloRoam's unlimited from $5 only pay off for heavy streamers or remote workers tethering a laptop, since Wireless@SG's free island-wide WiFi already covers light browsing without burning mobile data.
