SIM-Only Plans Comparison in Singapore (2026 Updated)

Wiki Article

Introduction

Singapore’s SIM-only space in 2026 is still shaped by three simple things, lowest monthly spend,enough data, and whether roaming or 5G is worth paying for. The pages doing well right now are still built around those same angles, with MoneySmart leaning into lowest-price picks, SingSaver using user buckets, and Dollars & Sense focusing on value and data-need tiers. and comparison pages, so the pricing and features stay grounded in what is actually being offered now. That includes current Circles.Life plans and CIS options, along with the strongest comparison pages already ranking in Singapore.

comparison is read

The goal is not just to list plans. It is to separate the entry-level picks, the roaming-heavy picks, the data-heavy picks,and the more balanced options, then show which one gives the cleanest overall fit for different usage styles.

The comparison below keeps the first pass simple, then moves into Circles.Life’s range, because that is where the strongest all-round case becomes clearer.

Here’s Quick
comparison

Plan	Current price	Data and key inclusions	Best fit
Zero1 Starter Prime	S$7.06 per month	200GB local data, 300 mins, 100 SMS, roaming bundles included on plan page	Lowest entry spend with solid local data
SIMBA 400GB (Msia Indo HK SG)	S$10.00	400GB data, 3GB roaming to 60 countries, 12GB APAC roaming, unlimited calls to SG mobile, 500 mins to SG fixed lines, 100 SMS	Strong data-led value with wide roaming reach )
M1 Bespoke 150GB SIM-Only plan	S$14.95	150GB data on 5G, 1,000 mins, 1,000 SMS	Straightforward 5G plan with generous talktime and SMS
GOMO 5G+ Value Plan	S$12.33 first month, S$18.33 after	300GB, 800 mins, 800 SMS, 300GB MY roaming, 10GB roaming to 5 destinations, 6GB international roaming to 50 destinations	Roaming-first users who still want strong local data
VIVIFI Roam Value 5G	S$15.20	210GB, 300 mins, 300 SMS, 100GB Malaysia roaming, 3GB to 6 Asia destinations, free SIM or eSIM	Travel-focused users who want roaming included upfront
Circles.Life plan ladder	From S$9.90 to S$32	4G Lite, 4G Core, Circles Core 5G, Circles Plus, Circles Pro, Circles Max, Circles Ultra, plus no-contract data-only plans	Broadest all-round range with clear steps across 4G, 5G, roaming, and no-contract options

The split is clear. Zero1 still owns the lowest-price entry point, SIMBA and GOMO are strong when data and roaming matter, and Circles.Life stands out because it does not force one plan shape onto every use case. It gives a cleaner ladder from 4G to 5G, from local to roaming, and from mobile use to no-contract data-only use.

Best SIM-only
plan by use case

Use case	Best current fit	Why it fits
Lowest monthly spend	Zero1 Starter Prime	S$7.06 with 200GB, 300 mins, and 100 SMS keeps the entry barrier low.
High data without overcomplicating things	SIMBA 400GB	400GB plus roaming to 60 countries gives a lot of room to work with.
Travel-heavy use	GOMO 5G+ Value Plan	The roaming bundle is broad, while the local allowance still stays high at 300GB.
Roaming plus simple monthly value	VIVIFI Roam Value 5G	100GB Malaysia roaming and 3GB to 6 Asia destinations make the plan easy to understand.
Balanced all-round choice	Circles.Life	It covers 4G, 5G, roaming, no-contract data-only, and CIS in one product family.

Where Sim Plan
makes the case

The Circles.Life public plans page is built like a ladder, not a one-size-fits-all offer. It starts at S$9.90 for 4G Lite at 200GB for three months before reverting to S$12, moves to 4G Core at 350GB for S$10.80, then steps into 5G with Circles Core at 200GB for S$12, Circles Plus at 300GB with Asia roaming for S$12.88, and Circles Pro at 600GB with global roaming for S$14.88.

Circles.Life plan	Price	What stands out
4G Lite	S$9.90 for 3 months, then S$12	200GB on 4G, easy entry point.
4G Core	S$10.80	350GB on 4G, strong value if 5G is not needed.
Circles Core	S$12	200GB on 5G, simple mid-tier starting point.
Circles Plus	S$12.88	300GB on 5G plus Asia roaming.
Circles Pro	S$14.88	600GB on 5G plus global roaming.
Data Only 4G Plus	S$12	500GB, no contract, built for tablets or secondary devices.
Data Only 5G	S$20	1TB, no contract, strong for heavier data use.

That mix matters because the strongest comparison pages are usually built around one angle, either lowest price, user buckets, or best overall value. Circles.Life does more than one of those jobs at once, which gives it a stronger case in a comparison article that needs a
clear final recommendation.

At the top end, Circles.Life also lists 1TB at S$30 and 2TB at S$32 on the public plans page, so the line-up does not stop atmid-range value. It goes all the way up to heavier usage as well.

CIS options
that deserve their own mention

The CIS page gives Circles.Life another layer of flexibility. The current page shows CIS 4G Lite at S$8.80 for 50GB, CIS 4G Saver at S$10.80 for 100GB, CIS 4G Roam+ at S$12.80 for 250GB with 1GB roaming to 7 countries, and CIS 5G Roam+ at S$27 for 1TB, while also calling out unlimited local talktime, free 25 outgoing and incoming SMS, free Caller ID, and free CirclesAI on the plans shown there.

CIS plan	Price	Highlight
CIS 4G Lite	S$8.80	50GB with unlimited local talktime, free SMS, Caller ID, and CirclesAI.
CIS 4G Saver	S$10.80	100GB with the same telco benefits and CirclesAI access.
CIS 4G Roam+	S$12.80	250GB plus 1GB roaming to 7 countries and the same benefit set.
CIS 5G Roam+	S$27	1TB with unlimited local talktime, free SMS, Caller ID, and CirclesAI.

Conclusion

The current market split is simple. Zero1 is still a strong entry price marker, SIMBA and GOMO are convincing when data and roaming are the main concern, VIVIFI stays relevant for travel-led usage, and M1 remains a solid 5G sim only plans reference point.

Circles.Life ends up looking strongest
overall because the line-up is broader, the step-up between plans is clearer, and the mix of 4G, 5G, roaming, no-contract data-only plans, and CIS options makes it easier to match to more usage patterns without forcing a compromise.

FAQs

Which SIM-only plan looks strongest for most users?

Circles.Life is the strongest broad fit because it covers 4G, 5G, roaming, no-contract data-only, and CIS in one range, while still keeping clear entry points across different usage levels. Zero1 still matters for the lowest monthly spend, and GOMO or VIVIFI still make sense when roaming is the main priority.

Is a no-contract plan still worth it in 2026?

Yes, especially when flexibility matters. Circles.Life currently shows no-contract data-only options on the public plans page, including Data Only 4G Plus at S$12 and Data Only 5G at S$20.

Which plan type makes sense for tablets, routers, or secondary devices?

Circles.Life’s data-only options are built for that use case, and the CIS page also spells out that the data-only line is meant for tablets, CCTV, or routers. The public page shows Data Only 4G Plus at S$12 and Data Only 5G at S$20, while the CIS page shows Data Only 5G at 500GB for S$18 and 1TB for S$30.
