Singapore’s mobile market runs on three networks — Singtel, StarHub, and M1 — each with at least one budget sub-brand or MVNO offering the same coverage at lower prices.

SimFinder’s database tracks 6 carriers and 21 plans in Singapore. Prices start at just S$10.80/month and go up to S$55/month. Nearly all plans are contract-free, and with Singapore being a compact city-state, coverage differences between the three MNOs are marginal.

This guide breaks down the entire Singapore SIM market using actual plan data, network quality scores, and pricing analysis.

The Singapore Mobile Landscape: Who Owns What

Singapore has three physical networks. Every carrier runs on one of these.

Quality data: OpenSignal 2025, measured June 2025

Unlike Australia or the US, where coverage varies dramatically between carriers, Singapore’s three networks are nearly identical in coverage (96-99/100). This is the advantage of being a 734 km² city-state — no rural dead zones to worry about.

The meaningful differences are in speed and price:

• Singtel leads in raw speed at 182.5 Mbps and has the lowest latency (12ms). It charges a premium for it — Singtel’s cheapest postpaid plan is S$35/month.
• StarHub sits in the middle at 155.8 Mbps. Its Giga! MVNO offers some of the best value in the market.
• M1 is the most competitive on pricing through both its own plans and Circles.Life. M1’s SIM Only 150GB at S$14.95 is the cheapest 5G plan from any MNO.

Price Breakdown: What Every Carrier Charges

MNO Plans (Singtel, StarHub, M1)

Budget Carriers (GOMO, Circles.Life, Giga!)

A striking pattern: budget carriers start below S$11/month — roughly a third of what Singtel charges for its cheapest postpaid plan. Circles.Life offers 350GB for S$10.80 — now the cheapest plan in the market after Giga! raised its 4G 100GB plan to S$10.90 in July 2026 — while Singtel’s Enhanced Lite gives just 300GB for S$35 (and locks you into a 12-month contract).

Best Value Plans by Use Case

Expats and Long-term Residents

M1 SIM Only 150GB 5G — S$14.95/month — The standout all-rounder. 150GB is more than enough for most users, 5G and eSIM are included, no contract, and the price is lower than any comparable MNO plan. M1’s network scores 89/100 overall, which in Singapore’s dense coverage landscape translates to consistent performance.

Circles.Life 5G Plus — S$18/month — If you want 5G on M1’s network but through a digital-first carrier with app-based management, Circles.Life offers 300GB with unlimited calls for S$18.

Tourists and Short-term Visitors

Singtel hi! 5G+ Prepaid Monthly — S$15 — The best prepaid option for visitors. 500GB of data with 5G, 500 voice minutes, eSIM support (activate before you land), and no contract. Singtel’s network is the fastest in Singapore at 182.5 Mbps.

Circles.Life 4G Core — S$10.80 — If you want maximum data on a budget, 350GB with unlimited calls at S$10.80 is hard to argue with. No 5G, but 4G in Singapore is fast enough for streaming and navigation.

Students and Budget Users

Circles.Life 4G Core — S$10.80/month — The cheapest plan in Singapore. 350GB with unlimited calls, running on M1’s network. Also the best per-GB value in the entire market.

Giga! 4G 100GB — S$10.90/month — Just S$0.10 more than Circles.Life but with less data (100GB vs 350GB). 100GB is still sufficient for social media, messaging, and moderate streaming, and it runs on StarHub’s network (97/100 coverage) with eSIM support — a solid alternative if you prefer StarHub’s network.

Heavy Data Users and Power Users

M1 SIM Only 1TB 5G — S$17.95 — A terabyte of 5G data for under S$18. Unless you’re tethering as a primary internet connection, this is effectively unlimited. No contract.

Giga! 5G 1TB — S$28.90 — Another 1TB option on StarHub’s network. More expensive than M1 but includes 1,500 voice minutes compared to M1’s 1,000.

Business Users

Singtel Enhanced Core Unlimited 5G — S$40 — True unlimited data with no caps, 700 voice minutes, and Singtel’s network (fastest speeds, lowest latency). The only unlimited plan worth considering if reliable, high-speed connectivity is a business requirement.

Singtel Priority Plus 5G — S$55 — The premium tier adds 1,000 voice minutes and priority network access. Only justified if voice calls are a significant part of your workflow.

5G and eSIM: What’s Available

5G

17 of 21 plans (81%) include 5G. The 4 plans without 5G are all budget-tier:

The cheapest 5G plan overall is M1 SIM Only 150GB at S$14.95. For budget carriers, Giga! 5G 300GB at S$15.90 is the entry point. The gap between 4G and 5G plans is narrow — just S$3-6 more in most cases — making 5G an easy upgrade in Singapore’s market.

eSIM

19 of 21 plans (90%) support eSIM. The two without eSIM are:

• Singtel hi! 4G Prepaid (S$12) — 4G prepaid, physical SIM only
• GOMO 4G Value (S$12) — budget 4G tier

Both are the cheapest offerings from their respective carriers. Every 5G plan in the database supports eSIM.

For travelers, this means you can activate a Singapore SIM before arriving — useful if you need data immediately upon landing at Changi Airport.

Travel eSIM Alternative

If you only need data for a short visit, travel eSIM providers like Airalo, Holafly, and Nomad offer Singapore data plans. These are data-only (no local phone number) and typically cost more per GB than local plans, but require no local registration. Use SimFinder’s travel eSIM search to compare options.

What Users Say

Online discussions about Singapore’s SIM market reflect a competitive landscape where budget MVNOs are gaining traction.

“Who’s offering the best deal in SIM-only, no contract plan right now? We find out by comparing Circles.Life, M1, MyRepublic, Singtel, StarHub, Zero1 and Zero Mobile.” — @hardwarezone (original post)

Community forums like HardwareZone Singapore consistently highlight that no-contract SIM-only plans are the default in the Singapore market, with the main decision being whether to go with an MNO for speed or an MVNO for price.

Individual experiences may vary based on location and network conditions.

Frequently Asked Questions

Which Singapore carrier has the best network?

Singtel leads with a 95/100 overall score, 99/100 coverage, and the fastest download speed at 182.5 Mbps. StarHub (91/100) and M1 (89/100) are close behind. In a city-state like Singapore, all three networks deliver strong coverage practically everywhere.

What is the cheapest SIM plan in Singapore?

Circles.Life 4G Core 350GB at S$10.80/month is the cheapest plan in Singapore. Giga! 4G 100GB, previously the cheapest option, rose to S$10.90/month in July 2026 — now S$0.10 more than Circles.Life for less than a third of the data. Both are MVNOs with no contracts.

Is 5G available on budget carriers in Singapore?

Yes. MVNOs and sub-brands offer 5G from as low as S$14.95/month (M1 SIM Only 150GB). Giga! offers 5G from S$15.90, GOMO from S$19.99, and Circles.Life from S$18. You do not need an MNO premium plan to access 5G.

Do Singapore SIM plans support eSIM?

What’s the best SIM for tourists visiting Singapore?

For short-term visitors, Singtel hi! 5G+ Prepaid Monthly at S$15 is a strong choice: 500GB data, 5G, eSIM activation before arrival, and no contract. Circles.Life 4G Core (S$10.80, 350GB) is the budget alternative with unlimited calls.

How does Singapore compare to other countries for mobile pricing?

Singapore offers some of the best value in Asia-Pacific. Plans with 100-350GB of data start below S$11/month. For context, comparable plans in Australia start around AUD $23-30 (roughly S$20-26). Singapore also has 90% eSIM adoption and 81% 5G availability across its 21 tracked plans.
