8 Best eSIM for Singapore 2026 (5G MRT Ready)

You step off the plane at Changi, open your Grab app, and it just spins. No signal. Your home carrier wants $12 per day for roaming. The SIM counter downstairs has a queue that stretches past the Jewel waterfall. This is why every traveller heading to Singapore needs an eSIM for Singapore ready before they board.

Singapore is a compact city state with three main mobile operators. Singtel is the largest and the only carrier with full 5G coverage across all six underground MRT lines, 1,700 outdoor locations, and 1,000 indoor locations including every shopping mall along the rail network.

StarHub and M1 both offer strong 4G and growing 5G networks. Because the country is only 733 square kilometres, every carrier blankets the island from Marina Bay to Jurong with near total coverage.

I tested eight eSIM providers across multiple Singapore layovers and business trips. Here are the ones that delivered consistent speed from Changi Terminal to Sentosa.

1. Airalo

Airalo routes its Singapore plans through StarHub, giving you access to one of the island's three major 5G networks. The Connect Lah plan starts at $4.50 for 1GB over 7 days and scales to 20GB for $26 over 30 days.

What matters for Singapore specifically is StarHub's strong performance across the CBD, Orchard Road corridor, and Changi terminals. Airalo also offers an Asia regional plan covering multiple countries on one profile, handy if Singapore is a stopover before Bangkok or Kuala Lumpur.

Why Airalo for eSIM for Singapore: StarHub's expanding 5G across the CBD makes Airalo a natural fit for business travellers bouncing between Marina Bay Sands conferences and Raffles Place meetings. The Asia regional plan adds genuine value for multi-country trips.

2. MobiMatter

MobiMatter operates as a marketplace, pulling Singapore eSIM plans from providers like RoamVault, Sparks, and TSimTech.

A Singapore-only 5GB plan from RoamVault costs $5.49 for 30 days. The 10GB option sits at $7.99. Where MobiMatter shines for Singapore is the ability to compare carriers and data amounts side by side before committing.

Sparks also offers a 6 country Asia bundle with 20GB for $22.99 that includes Singapore, Thailand, and Vietnam.

3. Maya

Maya lists Singapore plans starting from $2.99 for 1GB over 5 days, making it the cheapest entry point tested.

The 20GB plan covers 10 days and the 100GB option stretches across a full month. Every plan comes with a 100% money-back guarantee and Wi-Fi hotspot sharing included at no extra charge.

Scheduled activation lets you buy the plan weeks before your flight and set it to start the day you land at Changi.

Why Maya for eSIM for Singapore: A weekend layover at Changi does not need a $20 data plan. Maya's $2.99 starting price means you get enough data for Grab rides, Google Maps through Little India, and a few Instagram stories at Gardens by the Bay without overspending.

4. Amigo eSIM

Amigo eSIM routes through Singtel for its Singapore plans, which gives you access to the only carrier with confirmed 5G coverage inside all underground MRT tunnels.

That distinction matters if you rely on data during your commute from Changi to the city centre. Plans start around $5 for 1GB over 7 days and tethering is included on all packages.

The QR code install takes under three minutes and requires no manual APN changes.

Why Amigo for eSIM for Singapore: If you plan to ride the MRT daily and need data underground between Orchard and Marina Bay, Singtel is the only network with full 5G tunnel coverage. Amigo gives you that Singtel connection without the airport queue.

5. GigSky

GigSky dynamically switches between available Singaporean networks rather than locking onto one carrier.

Every new user receives a free 100MB trial lasting 7 days with no credit card needed. That is enough data to test speed at your hotel and confirm the connection works before spending anything.

Paid plans start at $3.99 for Singapore. The unlimited option throttles after 2.5GB per day but never cuts you off entirely.

6. Saily

Saily starts at $3.99 for 1GB over 7 days and scales to 20GB for $22.99 over 30 days for Singapore. Built by the NordVPN team, every plan includes ad blocking, tracker reduction, and a virtual location feature.

The 5G access covers supported areas across Singapore. Coverage reaches the Central Business District, Marina Bay, Changi Airport, and throughout the city on local network carriers.

7. iRoamly

iRoamly offers Singapore eSIM plans ranging from 500MB up to 500GB, with validity from one day to a full year.

The daily unlimited plan starts at $1 with 4G and 5G speeds. Hotspot sharing is included and unlimited on every package. For content creators filming at Marina Bay Sands or Gardens by the Bay, the 500GB option at $82 for 30 days provides more data than most providers even list.

8. Billion Connect

Billion Connect packages Singapore with Malaysia and Indonesia into one eSIM starting at $1.40 per day.

That makes it the obvious pick for travellers combining a Singapore stopover with a Kuala Lumpur weekend or a Bali holiday.

The Singapore-only plan starts around $3.40 with 4G and 5G access in 150+ countries. Installation is instant via QR code delivered to email.

Common Questions About eSIM for Singapore

Final Thoughts

For most Singapore visitors, Airalo on StarHub handles the basics well with clean pricing and a trusted app.

Amigo is the pick if underground MRT 5G matters to your daily routine. And Maya at $2.99 makes sense when you just need enough data for a layover or a weekend.

GigSky's free trial removes all risk if you have never used an eSIM before. Singapore's dense carrier coverage means almost any provider works. The question is really about price, data volume, and how long you are staying.
