If you’re looking for freedom and savings, cheapest SIM-only plans Singapore 2025 are the smart move. Think big data, no handset tie-ins, and the option to switch when a better deal appears.
Why go SIM-only (and who it’s best for)
SIM-only plans cut the fluff. No phone subsidy, just a SIM that gives you data, talk time and roaming. If you keep your phone for 2+ years, travel regionally, or want predictable monthly bills, a SIM-only plan usually saves you money. For light users, Zero1 or VIVIFI offer ultra-cheap 100GB options. For heavy streamers, M1 Maxx, SIMBA or MyRepublic give massive data at modest prices.
How to choose the right plan (quick checklist)
Think about these three things before you sign up:
- Monthly data needed — 100GB is plenty for many; pick 300GB+ if you stream daily.
- Roaming needs — travelling often? Look for APAC roaming or Singapore-Malaysia bundles.
- Contract flexibility — want to switch fast? Choose no-contract providers like Circles.Life, GOMO, or SIMBA.
Real tips to save more
Want the best bang for your buck? Port your number — many providers give intro rates for new sign-ups. Also, roll-over data or multi-month bundles (90 days) reduce waste. And yes, charge telco bills to a cashback card — that can shave extra off your monthly cost.
Quick picks (one-line): who to try first
- Best ultra-cheap: Zero1 / VIVIFI — solid 100GB starter plans.
- Best mid-tier value: MyRepublic / Giga! — large allowances, fair roaming.
- Best heavy data: SIMBA / M1 Maxx — 300GB+ plans that don’t break the bank.
