What Are The Best SIM-Only Plans In Singapore (2026 Edition)

Mobile data plans in Singapore used to come with a contract, typically a two-year plan, but also included handset subsidies to keep us hooked. Packaging both the mobile data and the handset in a monthly fee, these plans essentially function as an instalment plan for your shiny new mobile phone upgrade every two years.

If you do not recontract immediately at the two-year mark, you may continue paying the same monthly subscription even though you are no longer receiving a new handset subsidy. This is one reason SIM-only plans have become popular.

What Is A SIM-Only Plan?

SIM-only plans typically come with mobile data, talktime and SMS each month, without a subsidised mobile phone.

Many telco providers also offer no-contract SIM-only plans, allowing consumers the flexibility to switch to a competing telco that offers a better plan or better reception. Of course, there are also downsides to switching, such as waiting for a physical SIM card to be delivered and possible service disruption during number porting. Providers offering eSIMs can remove the need to wait for a physical card, although number transfers still require processing.

The other benefit is being able to choose when to upgrade your phone, rather than being tied to a two-year upgrading schedule. SIM-only plans also provide different mobile data options, depending on whether you are a heavy data user or do not use as much.

Many Options For Consumers In Singapore

Singtel, StarHub, M1 and SIMBA offer their own SIM-only plans. Consumers can also choose from mobile brands and mobile virtual network operators such as GOMO, giga, eight, Maxx, Circles.Life, Zero1, MyRepublic, VIVIFI, CMLink and ZYM Mobile.

There have also been changes to the providers available. redONE Mobile states that its Singapore subscriber lines were terminated from 12 September 2026, and directs customers to switch to eight. Its former plans are therefore excluded from this comparison.

Competition gives consumers a wide range of prices and data allowances to choose from, while putting pressure on operators to maintain service standards and offer more benefits.

Comparing SIM-Only Plans In Singapore

We’ll look at the SIM-only plans offered by different telcos and MVNO operators in Singapore to compare their prices and allowances.

The comparison uses advertised recurring subscription prices, excluding introductory bill discounts, cashback and free-month promotions. Recurring data allowances offered to current sign-ups are included. Where a benefit expires after a specified period, this is stated separately.

Not everyone has the same mobile data needs, so we shall consider two types of users:

User A represents those who have basic data needs of up to 200GB. This would include someone who uses mobile data mainly for communication, entertainment during commutes and occasionally connecting a laptop to a mobile hotspot.

User B represents those who have extreme data needs of over 200GB. They may work offsite frequently or use large amounts of mobile data for streaming and hotspot connectivity.

The tables also compare local outgoing talktime, SMS and roaming allowances. Prices include GST. Where a provider bills every 30 days rather than by calendar month, this is indicated. Optional add-ons and chargeable services are additional.

Roaming bundles labelled “Asia”, “APAC”, “SEA”, “global” or “worldwide” cover the provider’s specified destinations and preferred networks. They do not necessarily cover every country in the named region.

Absolute Lowest Price And Best Overall Value

Among the plans compared, Zero1 Starter FE and VIVIFI Roam Value both provide 200GB of local data at $7.70 a month. Both include roaming allowances, although the larger Malaysia bundles have yearly validity rather than refreshing every month.

However, given the price difference, you may want to make a small top-up to enjoy a larger mobile data allowance, even if you are not yet a heavy user. Several plans in the next category cost less than $10 a month.

Best SIM-Only Plans For Extreme Data Needs (Over 200GB)

Unless stated otherwise, data, talktime, SMS and roaming allowances below recur monthly. Bundles with yearly or 365-day validity are not monthly allowances. “Unlimited” benefits remain subject to the provider’s fair usage and traffic management policies.

M1’s prices above are base subscription prices. Its promotional terms provide two free months of Caller Number Display for eligible online sign-ups, followed by $5.45 a month. Confirm the ongoing 5G access terms for the selected offer before subscribing. The advertised unlimited weekend data benefit is free for 12 months.

CMLink also advertises additional sign-up roaming bundles. For its $10.10 and $11.10 plans, these include 600GB shared across Malaysia, Indonesia and Thailand for 365 days for new sign-ups, and 30GB international roaming for 365 days for eligible new and port-in customers. The $15 plan instead advertises 1TB and 60GB respectively. These are separate from the monthly roaming allowances in the table.

For MyRepublic’s 5G plans, the included monthly roaming data is valid for seven days from first usage. Its local data can continue at managed speeds after the high-speed allowance is used, subject to fair usage.

For VIVIFI Share, the $41 main-line fee does not cover an entire household on its own. Additional lines normally cost $6.50 a month each. The advertised SHARE388 promotion reduces this to $3.88 per additional line for 12 months and requires a main line and at least one additional line when signing up.

Cheapest Overall Price

Even for SIM-only plans offering more than 200GB, some of the cheapest options cost less than $10 a month. Among the plans compared, MyRepublic’s 300GB 4G plan has a recurring subscription of $7.90, while Circles Core provides 500GB at $8.

The allowances and conditions differ. Circles Core’s free 5G access lasts six months, while other plans may include separate monthly and yearly roaming bundles.

Best Overall Value

M1’s 1TB Bespoke SIM-only plan has a base subscription of $17.95 a month. However, chargeable add-ons such as Caller ID affect the total recurring cost, so these should be included when comparing it with plans that bundle the same services.

Meanwhile, VIVIFI Share allows family members to share local data, talktime and SMS. Its main-line subscription is $41 a month, with an additional charge for each supplementary line. Its 600GB Malaysia, Indonesia and Thailand roaming bundle and 30GB Asia roaming bundle are yearly allowances.

Frequent Travellers

Many operators now offer plans with roaming to Malaysia, Southeast Asia, the wider Asia-Pacific region and international destinations. Depending on your travel needs, these can offer good value.

Check whether the advertised roaming data refreshes monthly, is shared with your Singapore allowance, or expires after a specified period. A large yearly roaming bundle is different from a smaller allowance that renews every month. Preferred-network requirements, fair usage limits and any validity period triggered by first use also matter.
