Note: This story has been updated with the latest comparisons and analysis, accurate as of 4th November 2025.
Let's face it. We all love a good bargain.
Looking for a good bargain is a part of all of us. We previously scoured (in March and April 2025) to find the most affordable SIM-only plans in the market and found them to be bundled around two major price points, S$7 and S$10 per month. Since then, to the benefit of consumers like you and me, the bundled perks have improved, but the prices have held steady. We also found several plans now offer a year-long roaming data bundle to select countries, so that's yet another interesting development. Here's our May 2025 update on this landscape that we've compiled.
Points to consider
But price isn’t the only factor you need to consider.
One other point to look out for, is if you have a particularly strong preference for the network provider behind the service offerings and if only a physical SIM card is supported or if an eSIM is an option. Remember, a mobile plan can also be used with LTE-supported devices such as smartwatches and even certain business laptops, so these extra considerations can help you refine what you need to look out for in your next mobile plan.
Additionally, the trend of increasing roaming data allocation in your mobile package has continued, with changes coming in the bundled capacity and locations. Thankfully, they still offer free incoming calls and caller ID.
To give you a better perspective of how all the different low-cost service offerings stack up, we looked across all the mobile service operators to find the latest and most affordable SIM-only, no-contract price plans they've got and compiled their offerings for easy reference. Our focus is still on monthly plans that cost about S$10 or less.

Our favourite Sub-S$10 mobile service plans
The biggest change from the previous chart is the removal of the My Republic “Xlit Plan 4G” (with the plan being retired), leaving only its “Essential Plan” in our Sub-S$10 per month category. However, CMLink makes an appearance with its new 100GB plan for S$7.70.
From the chart, we felt that Eight still offered the best value plan which was its “288GB plan”, now known as the "Double Eight Plan", along with M1's Maxx. On both services, you get generous data allotment covering both Singapore and Malaysia, with no expiry date. Plus, you get extra APAC and non-APAC roaming data, as well as generous talk time. Now, the choice of preference between them comes down to whether you want it cheaper, which M1 has a slight edge for the first year, or if you prefer to have IDD talk time, which Eight offers. redOne’s new plan shares its roaming data across 16 countries including China, Macau, Hong Kong, Taiwan, South Korea, Japan, India, Philippines, Vietnam, Australia, New Zealand, Brunei, Cambodia, Laos, and Myanmar.
If you’re still after sign-up perks, then ZYM Mobile’s offerings haven’t changed and look reasonably attractive, plus it's on Singtel's backbone if that interests you.

Our favourite S$10 mobile service plans
Simba once again ruled the roost for us. Besides being the only one still offering 5G coverage, its S$10 plan offered 300GB of local data for use in Singapore, Hong Kong, and Malaysia. Note that it's the only one to allow local data use in Hong Kong. M1's Maxx S$10 plan looks attractive to those looking to make IDD calls to ASEAN countries, every discount certainly helps. If you're looking for a good amount of local data, then the MyRepublic plan could be what you need.
Interestingly, Zero1’s “Streamo Bold” and ZYM Mobile’s “Roam Plus” plans both have 600GB of roaming data covering Malaysia and Indonesia that is valid for one year (doesn't reset every month), and 5G for the first three months. Could it be because both run over the same network provider, or will ZYM Mobile’s perks win it for you?
Last, but not least, if you're willing to put in a dollar more than all other comparisons here, Eight has a "Triple Eight Plan" that offers that can match the best of the ASEAN roaming data offers, plus 28GB of APAC roaming, and 10GB of International roaming. There's also Simba to consider if you need massive IDD minutes per month on its S$12 plan.
