The cheapest 5G SIM only plan at 13 brands, plus SIM only plans for seniors and unlimited data plans, from each telco's own page
Each brand's cheapest no-contract 5G SIM only plan open to anyone, at its usual monthly price: the price you pay once any offer ends. Plans billed every 30 days are worked out to a calendar month.
Bars start at S$0; the scale runs to S$40. Offers are in the first-year table below.
Singtel's cheapest no-contract 5G SIM only plan is S$40 a month (unlimited data). GOMO, which says on its own site that it runs on Singtel's network, starts at S$19.99 (400GB), and hi! by Singtel at S$15 every 30 days (500GB).
10 of the 13 cheapest 5G plans show an offer. M1's S$11.95 lasts 3 months, then S$14.95; giga's S$7.95 lasts 3 months, then S$15.90. We rank the price after the offer ends.
ZYM Mobile's plan cards lead with totals such as 1,790GB. Only 700GB of that is Singapore data; the rest is roaming (ZYM's Roam Smart card: 700GB Singapore, 1,000GB Malaysia-Indonesia-Thailand roaming, 30GB and 60GB wider roaming). Every figure here is Singapore data.
Circles Core includes 5G free for 6 months. ZYM's Roam Plus 4G gets 5G+ for 180 days on a new number, and Zero1's Jumbo plans come with a 6-month 5G+ trial. None of these counts as a 5G plan here.
Circles.Life's Senior Core is S$5 a month for 500GB, and SIMBA's seniors plan is S$5 every 30 days. M1's seniors plan is S$5 for the first 12 months, then S$14.95.
MyRepublic's reward plans show S$6 a month, but the bill is S$8: S$2 of reward coins offset it for four months. We rank the S$8.
eight's 588GB plan is S$10.80 a month, or S$96 for a year paid up front: S$8 a month. eight says this saves S$33.60 a year.
redONE says on its own site that it ended every subscriber line on 12 Sep 2026 and pointed customers to eight. Changi Mobile stopped in February 2026; its old web address now points to an unrelated site.
Each brand's cheapest plan sold only to seniors, at its usual monthly price. Most say 60 or older; M1, SIMBA and Circles.Life don't state an age on the plan page we read.
Bars start at S$0; the scale runs to S$20.
Each brand's cheapest no-contract plan with unlimited Singapore data, at its usual monthly price. All are 5G except MyRepublic's, which is 4G.
Bars start at S$0; the scale runs to S$40.

This comparison covers 13 brands priced, 94 plans read, 19 found. Every price comes from the business's own website, read and dated, and the comparison was last verified on 26 Sep 2026. No business pays to be included or to rank.
The ladder at the top lines up every business from cheapest to priciest. Below it are the standout findings, how prices spread out, and the details that matter before you book or buy. We compare prices that are comparable enough, not identical, and “The boring bit” says exactly where we drew the line.
Every brand we could find selling SIM only mobile plans in Singapore: the four networks (Singtel, StarHub, M1, SIMBA) and the brands that sell plans on them. We found 19 names and read 13 brands' own websites, 94 plans in all. Three couldn't be read, two have closed and one no longer sells mobile plans; they're listed below. Figures are among brands that publish prices.
Ladders use each plan's usual monthly price: the price once any offer ends, with no contract. Plans billed every 30 days are worked out to a calendar month (S$10 every 30 days is S$10.14 a month, since a year has 12.17 bills); plans paid for 90 days or a year up front are shown separately. Data means Singapore data only: many pages lead with totals that add roaming, which we leave out. A plan counts as 5G only if 5G comes with it for good; free 5G for a few months doesn't count. We don't judge network quality, roaming or talktime, which differ a lot between plans with the same price.
Offers (first months free or half price, port-in deals) are never ranked; they're in the first-year table and the master table. Plans for youth or students (GOMO Youth 400GB, GOMO Youth Unlimited, giga Youth 400GB) are in the master table only. Data-only SIMs (StarHub Data Only Core S$5, StarHub Data Only Plus S$15, ZYM Mobile Flexi Duo (data SIM) S$7) have no calls, so they aren't on the ladders. Singtel's Enhanced Lite (S$35, 300GB) needs a 12-month contract, so it isn't on the no-contract ladders. Zero1's S$12 700GB plan isn't ranked: its page text doesn't tie a name or network to it.
Every price is from the brand's own website, read on 26 Sep 2026 by our own headless browser, which saves a text copy, the page code and a screenshot. StarHub's senior and Platinum prices come from the plan data its own shop page loads; ZYM Mobile's plans are images on its page, read from the screenshot; eight's page was read from its page code. Telco prices change often, sometimes weekly: check the brand's page before you sign up.
