Best eSIM for Singapore (2026): Cheapest 30-Day Plans Compared

This guide compares 30-day Singapore eSIM prices, explains airport SIM card alternatives, and looks at local network coverage from major operators such as StarHub, Singtel, and M1.

Best eSIM for Singapore: 30-Day Price Comparison

The table below compares Singapore eSIM plans from Roafly and selected international eSIM providers. All plans are listed in USD, and the 5GB, 10GB, and 20GB options are valid for 30 days unless stated otherwise.

Prices are accurate as of July 4, 2026. Prices, operators, coverage conditions, and fair usage policies may change.

eSIM Provider Notes

Roafly

Roafly is the strongest value option in this comparison for Singapore travelers who want a clear data allowance, 30-day validity, and access to a reliable local network. The 20GB plan at $20.00 is especially competitive because it gives travelers a lower price than the equivalent 20GB options from Airalo, Saily, Roamless, aloSIM, and Yesim.

Roafly’s Singapore eSIM uses StarHub, of the country’s major mobile operators. StarHub states that its 5G coverage reaches more than 99% across the island, which is a strong advantage for visitors staying in areas such as Marina Bay, Orchard, Chinatown, Bugis, Sentosa, Little India, Clarke Quay, and Changi. 

You can check the latest Singapore eSIM packages on the Roafly Singapore eSIM page.

Airalo

Airalo offers Singapore eSIM plans on StarHub, with pricing close to Roafly at lower data levels. The 5GB plan is $10.00, which is slightly higher than Roafly’s $9.90 plan. The difference becomes more visible at 10GB and 20GB, where Airalo costs $16.00 and $23.00.

Airalo is a familiar name for many international travelers. It can be a good option for users who already manage several eSIMs through its app, but price-sensitive travelers may find Roafly more competitive for Singapore.

Saily

Saily lists competitive 30-day prices for Singapore, especially at 5GB and 10GB. Its 20GB plan is $22.99, which is still higher than Roafly’s $20.00 plan.

The main detail to note is that the operator is not specified in the provided comparison. That does not automatically mean weak coverage, but travelers who care about knowing the exact local network may prefer a provider that clearly lists the operator.

Roamless

Roamless uses Singtel for Singapore in this comparison. Singtel is of Singapore’s strongest networks and has achieved more than 95% nationwide 5G standalone coverage, according to its official announcement. 

Roamless pricing is also close to the market average: $9.95 for 5GB, $15.95 for 10GB, and $22.95 for 20GB. It is a solid option, but Roafly remains cheaper across the three directly comparable data tiers.

aloSIM

aloSIM uses StarHub for Singapore, similar to Roafly and Airalo. Its prices are $10.00 for 5GB, $16.00 for 10GB, and $23.00 for 20GB.

The pricing is almost identical to Airalo in this comparison. Travelers choosing between aloSIM and Roafly should mainly compare price, app preference, support experience, and installation flow.

Yesim

Yesim uses Singtel in this comparison, which is a strong network choice for Singapore. However, its prices are higher than the other fixed-data options here: $10.80 for 5GB, $20.40 for 10GB, and $27.60 for 20GB.

Yesim may still appeal to users who prefer its platform or need a specific plan type, but for a standard Singapore trip, the price gap is noticeable.

Holafly

Holafly is different because it focuses on unlimited-style plans rather than fixed 5GB, 10GB, or 20GB data packages. In this comparison, Holafly’s approximate 7-day unlimited plan is $27.50.

Unlimited plans can be convenient for travelers who do not want to track data usage. However, unlimited eSIMs may include a fair usage policy, which can reduce speed after heavy use. For travelers who know their expected usage, a fixed 10GB or 20GB plan can be more cost-effective.

Airport SIM Cards in Singapore: Are They Worth It?

Singapore Changi Airport makes it easy to buy a tourist SIM card after arrival. Changi Airport lists Singtel, StarHub, and M1 as leading SIM card providers available to travelers. 

The main benefit of an airport SIM is that some tourist SIM cards include local calls and SMS. This can be helpful if you need a Singapore phone number for restaurant bookings, local calls, or certain services.

The downside is convenience. You may need to find a counter, show your passport, wait in line, and swap or register a physical SIM. If you land late, arrive during a busy period, or want internet immediately for Grab, Google Maps, WhatsApp, or hotel check-in, an eSIM is usually smoother.

StarHub states that its tourist plans and traveler eSIMs start from S$12 and are available for collection at Changi Airport arrival halls in all four terminals. Singtel also publishes tourist options such as $12, $15, and $30 tourist plans on its official prepaid tourist SIM page.

For most short-term visitors, the decision is simple: choose an airport SIM if you need local calls and SMS; choose an eSIM if you want data ready before landing.

Local Operators in Singapore: StarHub, Singtel, and M1

Singapore has excellent mobile infrastructure. It is a compact city-state, so network quality is generally strong in tourist areas, business districts, transport hubs, malls, and residential neighborhoods.

StarHub Coverage

StarHub is the operator used by Roafly in this comparison. It is of Singapore’s main mobile networks and has strong 4G and 5G availability across the island.

StarHub says its 5G network covers more than 99% across Singapore. This is important for travelers because many Singapore itineraries involve dense urban areas, indoor malls, MRT stations, hotels, and waterfront locations. Good indoor and urban coverage helps with navigation, ride-hailing, mobile payments, and video calls.

For a visitor, StarHub is a reliable network choice. It performs well in the places tourists usually spend time: Marina Bay Sands, Gardens by the Bay, Orchard Road, Bugis, Kampong Glam, Chinatown, Sentosa, and Changi Airport.

Singtel Coverage

Singtel is Singapore’s largest and most established telecom brand. It is used by Roamless and Yesim in this comparison.

Singtel announced that its 5G network surpassed 95% nationwide coverage in 2022, including outdoor locations, buildings, and transport-related areas. Singapore’s government also notes that the country achieved nationwide 5G standalone progress early, with the first two 5G standalone networks reaching 95% nationwide outdoor coverage by the end of 2022.

For travelers, Singtel is a strong network choice. It is especially attractive for users who prioritize broad network reputation and stable performance in transport hubs and central areas.

M1 Coverage

M1 is another major Singapore operator and is commonly available through local prepaid and tourist SIM options. M1 says its 5G coverage is available in more than 99% of Singapore islandwide.

Although M1 is not listed as the network for the eSIM providers in the comparison table above, it remains relevant for travelers considering a physical SIM card at the airport or in the city.

How Much Data Do You Need in Singapore?

Singapore is a highly connected destination. Hotels, malls, airports, cafés, and attractions often have Wi-Fi, but relying on public Wi-Fi is not ideal. You will still need mobile data for maps, ride-hailing, messaging, ticket QR codes, translation, banking alerts, and restaurant searches.

• 5GB plan is enough for light users. Choose this if you mainly use WhatsApp, Google Maps, email, and occasional browsing.
• 10GB plan is better for most travelers. It gives more room for social media, short videos, ride-hailing, and daily navigation.
• 20GB plan is the best choice for heavier use. Choose this if you upload videos, use Instagram and TikTok frequently, work remotely, join video calls, or hotspot your laptop.

For most Singapore trips, 10GB to 20GB is the comfortable range. Singapore is a compact country, but travelers often use mobile data heavily because so much of the trip depends on real-time apps.

For a better estimate, use Roafly’s Data Usage Calculator before choosing a package.

eSIM vs Physical SIM in Singapore

An eSIM is usually better if your phone supports it. You can install it before departure, activate it when you arrive, and avoid dealing with airport counters.

A physical SIM is better if your phone does not support eSIM or if you need a local Singapore number. Some local tourist SIMs include calls and SMS, while most travel eSIMs are data-only.

There is also a practical difference. With an eSIM, you can keep your home SIM active for banking SMS, two-factor authentication, and emergency calls. This is useful when traveling internationally.

Before buying any eSIM, check that your phone is unlocked and eSIM-compatible. Most recent iPhone, Samsung Galaxy, and Google Pixel models support eSIM, but compatibility can vary by region and carrier.

Best Singapore eSIM by Traveler Type

For first-time visitors, Roafly’s 10GB plan is a balanced choice. It gives enough data for maps, messaging, attraction tickets, and daily browsing without overpaying.

For digital-heavy travelers, Roafly’s 20GB plan offers the best value in this comparison. At $20.00 for 30 days, it is cheaper than the 20GB plans from Airalo, Saily, Roamless, aloSIM, and Yesim.

For travelers who want a known Singtel-based option, Roamless is the most competitively priced Singtel choice in the table.

For travelers who want unlimited-style usage and do not mind a higher short-term price, Holafly can be considered. Just check the fair usage conditions before buying.

For most Roafly customers, the key advantage is the combination of price, StarHub access, simple installation, and 30-day validity.

Travel Connectivity Tips for Singapore

Install your eSIM before your flight, but activate data roaming when you arrive in Singapore. This helps avoid using the plan too early.

Keep your primary SIM active if you need SMS from your bank or airline. Set your Singapore eSIM as the mobile data line.

Download offline maps as a backup. Singapore has strong coverage, but offline maps are useful inside large malls, underground walkways, and airport terminals.

Use Wi-Fi for very large downloads. Even with a 20GB plan, cloud backups and video uploads can use data quickly.

Final Verdict: What Is the Best eSIM for Singapore?

The best eSIM for Singapore is the that gives you strong local coverage, clear pricing, enough data, and easy installation before arrival.

Based on the 30-day price comparison, Roafly is the best value option for 5GB, 10GB, and 20GB fixed-data plans. It uses StarHub, offers competitive pricing, and supports simple setup through Direct Install, QR Code, or Manual installation.

Airalo, aloSIM, Saily, Roamless, Yesim, and Holafly all have valid use cases, but Roafly stands out for price-performance balance. For most visitors, the 10GB plan is the safest middle option. For heavier users, the 20GB plan offers the strongest value.

If your trip continues from Singapore to nearby Asian destinations such as Malaysia, Thailand, Indonesia, or Vietnam, you can also choose an Asia eSIM instead of buying separate country plans for each stop.
