TL;DR: Best SIM-Only Plans Singapore (Jul 2026)

*Circles.Life currently advertises the 5G Pro plan at a promotional price. As such, check how long the rate applies and what you will pay afterwards.

Plan prices and benefits can change. Before signing up, confirm the latest details on the provider’s official website.

What Is a No-Contract SIM-Only Plan?

A SIM-only plan gives you mobile data, calls and SMS without bundling a phone.

As a result, the monthly bill is usually lower than a traditional handset contract. At the same time, you can continue using your current phone instead of upgrading.

Still, “SIM-only” does not always mean “no contract”. Some plans may require a six- or 12-month commitment.

Before you sign up, check:

• The minimum contract period
• Early-termination fees
• SIM or eSIM charges
• Promotional price periods
• Roaming renewal terms
• Fair-usage limits

Can You Keep Your Existing Mobile Number?

Yes, you can usually port your current Singapore number to a new telco.

To start, make sure the line is still active. Next, check that it is registered under the correct identification details.

Most importantly, do not cancel your old line before the port is complete. Otherwise, you may lose the number.

Port-in gifts can be attractive too. Even so, the long-term monthly cost should matter more than a one-off freebie.

Which SIM-Only Plan Is Best in Singapore?

The best mobile plan in Singapore depends on how you use your phone.

For starters, check your average usage over the past few months. From there, compare the factors below.

Local data

Large allowances may look impressive at first glance. In reality, you may not need 500GB or 1TB if you spend most of the day on home or office Wi-Fi.

5G access

A 5G plan may offer faster speeds and smoother streaming. On the flip side, you will also need a compatible phone and decent 5G coverage in your area.

Roaming

Some plans are built around Malaysia and nearby Asian destinations. Others spread a smaller allowance across more countries.

In other words, the best option depends on where you travel most often.

Rollover data

Rollover can be useful when your usage changes from month to month. Keep in mind, though, that providers may cap how much data you can carry forward.

Promotional pricing

A low advertised price may only last for a few months. For that reason, always check the recurring price after the promotion ends.

Customer support

Digital telcos often provide support through apps or online chat. By comparison, the main telcos may offer physical stores and phone assistance.

Ultimately, a useful SIM-only plan comparison in Singapore should look beyond the headline number of gigabytes.

Which Singapore Telco Has the Best Reception?

Singapore has four main mobile network operators:

• Singtel
• StarHub
• M1
• SIMBA

Alongside them, many mobile virtual network operators, or MVNOs, use these networks to offer their own plans.

Even so, there is no single best network for everyone. Coverage may vary depending on your home, workplace, MRT route and device.

For a clearer picture, check IMDA’s latest coverage results. It also helps to ask friends or colleagues who use the same network in the areas you visit most.

Main Telco or MVNO?

A main telco may suit you if you prefer physical stores and direct phone support.

An MVNO, on the other hand, may charge less for a similar amount of data.

That does not mean the overall experience will be identical. Customer support, roaming options and network arrangements can still differ.

Cheapest SIM-Only Plans Under $15 a Month

Looking for the cheapest SIM-only plan in Singapore?

The good news is that plans below $15 now offer far more data than they used to.

Best Cheapest Plan: VIVIFI Roam Value

At $7.70 a month, VIVIFI Roam Value is a strong low-cost choice.

You get 200GB of local data, which should be enough for most everyday users. On top of that, the plan includes 5GB of roaming across selected Asian destinations.

The main drawback is that it is a 4G plan. If 5G matters to you, Circles.Life 5G Pro may be a better fit.

Best for Heavy Data: VIVIFI VIBE

VIVIFI VIBE costs $10 a month and includes 600GB of local 4G data.

You also get 15GB of Asia roaming.

Because of that, the plan may suit heavy streamers and hotspot users who do not mind staying on 4G.

Best Affordable 5G Plan: Circles.Life 5G Pro

Circles.Life currently advertises its 5G Pro plan at $12.99 a month.

The plan offers up to 1TB of 5G data, roaming benefits, eSIM support and CirclesAI features.

For the price, that is a generous package. That said, the rate is promotional, so check the offer period and later recurring fee before you sign up.

Mid-Range SIM-Only Plans From $15 to $30

Mid-range plans now offer much more than 50GB or 100GB.

Instead, many include several hundred gigabytes, 5G access and regional roaming.

Best Mid-Range Plan: VIVIFI Roam Asia Super 5G+

At $15 a month, this plan includes 700GB of local 5G+ data.

It also comes with 30GB of Asia roaming.

Taken together, those benefits make it a strong-value option for users who travel around the region.

Best for Rollover Data: giga! 300GB

giga!’s 300GB plan costs $15.90 a month.

Unused data can roll over, subject to the provider’s limits. As a result, the plan may suit users whose data needs change from one month to the next.

Best for Singapore and Malaysia: giga! 400GB

The $18.90 giga! plan includes 400GB usable in Singapore and Malaysia.

That makes it especially convenient for users who cross the Causeway regularly.

Best for Wider Roaming: GOMO 5G+ Value

GOMO’s 5G+ Value plan costs $19.99 a month after its introductory pricing.

Besides local data, it includes Asia and worldwide roaming allowances.

This makes it more appealing to users who travel beyond Malaysia and nearby destinations.

Premium and Unlimited SIM-Only Plans

Higher-tier plans focus less on the size of the local data bundle.

Instead, they tend to offer unlimited data, wider roaming, unlimited calls or extra device benefits.

Best for Asia Travel: GOMO 5G+ Asia Infinity

This plan includes unlimited local and Asia roaming data, subject to fair usage.

Because of that, it may suit frequent regional travellers.

Occasional travellers may not need to pay this much, though. A cheaper local plan plus a travel eSIM could cost less.

Best Main-Telco Unlimited Plan: StarHub 5G Unlimited+ Core

StarHub’s Core plan costs $38 a month.

It includes unlimited local 5G data, calls and SMS.

For users who prefer a main network operator, it offers a simpler unlimited-data option without jumping to the higher Plus or Max tiers.

Best for Worldwide Roaming: GOMO 5G+ Global Infinity

At $50 a month, this plan is much more expensive than the budget choices.

In return, it includes unlimited local and worldwide roaming data across selected destinations, subject to fair usage.

For frequent international travellers, that convenience may justify the higher cost.

SIM-Only Plans for Seniors and Families

Some providers offer special plans for seniors and households with several lines.

For example, GOMO has a senior plan for users aged 60 and above. Singtel also offers senior mobile plans.

Families have options too. VIVIFI Share allows users to share 500GB of local data, with the main line costing $41 a month and add-on lines starting from $6.50.

As a result, a shared plan may cost less than several separate premium plans.

Before deciding, though, compare the total household cost and check what happens to the add-on lines if the main account is cancelled.

Are SIM-Only Plans Worth It?

A SIM-only plan may be worth it if your current phone still works well.

For one thing, you avoid paying for a new device through your mobile bill. At the same time, you can compare your handset and mobile plan as separate expenses.

A handset contract may still make sense if:

• You already planned to buy a new phone
• The full package costs less overall
• You qualify for a corporate or family discount
• You are comfortable with a longer commitment

Either way, compare the total cost over the full contract period.

In the end, the best no-contract mobile plan in Singapore is the one that gives you enough data, coverage and roaming without making you pay for benefits you will not use.

Before signing up, check the recurring price, promotional period, contract terms and fair-usage limits.
