How Much Do the Cheapest SIM-Only Plans Cost?
The cheapest SIM-only plans in Singapore in 2026 start from about $8/month for 80GB of 5G data on no-contract MVNO deals. That's nearly 60% cheaper than a typical big-telco postpaid plan! SIM-only means you keep your current phone and just swap the SIM (or eSIM) — no lock-in, cancel anytime.
Here's the definitive move: if you already own your phone and don't need a handset subsidy, a SIM-only plan is almost always the cheaper choice. A $15/month 100GB SIM-only plan saves you around $180–$300 a year versus a $40/month bundled contract.
Watch out for promo pricing! Many "$8" headline rates are intro offers for the first 6–12 months, then renew higher. Always check the ongoing price. Grab the ones with permanent pricing if you want zero surprises.

Singtel vs StarHub vs M1: Which Big Telco Wins?
Among the big three, Singtel offers the widest and most reliable 5G coverage, StarHub leads on bundled entertainment (Disney+ and HBO perks), and M1 is usually the cheapest of the trio on SIM-only. All three run nationwide 5G Standalone networks reaching over 95% outdoor coverage in 2026.
Singtel is the premium pick — rock-solid network, Priority Pass perks, and strong family group plans. Expect SIM-only from around $25–$35/month for 100GB+. Their coverage shines in the MRT tunnels and heartland alike.
StarHub is the entertainment king. Bundle a plan with streaming and you grab serious value if you binge shows. Their 5G plans often throw in 150GB+ and free subscriptions during promos.
M1 is the value champ of the big three. Their Bespoke and SIM-only plans frequently undercut rivals, with customisable data from ~$18/month. If you want a trusted big-name network without the big-name price, M1 is your lobang.

MVNOs: Are GOMO, Circles.Life & giga Worth It?
Yes — MVNOs (mobile virtual network operators) offer the best value mobile plans Singapore has in 2026, running on the same Singtel, StarHub and M1 networks for a fraction of the price. GOMO (on Singtel), giga (on StarHub) and Circles.Life (on M1) deliver 80GB–100GB+ of 5G for $8–$18/month with no contract.
The trade-off? MVNOs are app-first with limited physical stores and fewer bundled perks. But if you're comfortable managing your plan online, the savings are real. Circles.Life is famous for flexible data top-ups and no-contract freedom. GOMO keeps it dead simple with one generous flat plan. giga regularly runs the cheapest headline prices in town.
Definitive tip: since MVNOs ride the big telcos' towers, you're getting the same coverage for less — you're really just paying less for the brand name and shopfront. Shiok, right?
Phone Bundles & Contract Deals: Worth the Lock-In?
Phone bundles make sense only if the handset subsidy beats paying SIM-only plus buying the phone outright. In 2026, a flagship like the latest iPhone or Samsung Galaxy on a 24-month contract typically commands a plan of $50–$90/month — but you save several hundred dollars upfront on the device.
Do the maths: multiply the monthly plan by 24, add any upfront device cost, then compare against (SIM-only × 24) + outright phone price. Often the SIM-only route wins unless there's a fat subsidy or trade-in bonus. During big sales, telcos offer trade-in top-ups worth $100–$400 — stack those for max savings.
Want the absolute best handset prices? New phones also drop hard during Amazon Prime Day 2026 Singapore and the 9.9 and 11.11 mega sales — sometimes buying outright during a sale beats any contract subsidy!

How to Save Even More on Your Mobile Plan
The easiest way to save on your mobile plan in Singapore is to switch to SIM-only and port your number — most Singaporeans overpay by $100–$200 a year by staying on old postpaid plans. Review your actual data usage: if you average under 40GB/month, you're likely paying for data you never touch.
- Port your number: keep your digits and grab new-sign-up vouchers — switching is free and takes minutes.
- Stack card rebates: pay with cards like the DBS Live Fresh or UOB One for extra cashback on telco bills.
- Time it with sales: sign up during 9.9, 11.11 or National Day promos for waived fees and bonus data.
- Use family/group plans: big telcos discount multi-line accounts — rope in your family for lower per-line cost.
- Go eSIM: instant activation, no delivery wait, and easy dual-SIM for work and play.
