How Much Are Singaporeans Overpaying on Phone Plans — and What to Switch To
Most Singaporeans on 2-year contract plans pay $50–$80/month for phone+plan bundles. SIM-only plans on MVNOs deliver comparable data (30–100GB) for $10–$25/month. The annual saving from switching is $300–$600 per person.
If you finished paying off your phone months ago but your bill never dropped, you're almost certainly still funding a handset subsidy you've already settled. Singapore's SIM-only and MVNO plans now match contract data for a fraction of the price — the catch is knowing which tier actually fits your usage. Here's the gap, line by line.
The verdict
For Singaporeans who own their phone outright (or have finished a contract cycle), switching to a SIM-only plan immediately saves $300–$600/year per line. The best value plans in 2026 are offered by MVNOs (Giga, Zero1, Circles.Life) and by the main telcos' own SIM-only tiers. A couple on two contract plans at $60/month each can save $600–$1,000/year simply by porting their numbers to SIM-only equivalents. The only reason to stay on a contract plan is if you need a subsidised phone — and in that case, buying the phone separately and using a SIM-only plan is still usually cheaper over 24 months.

Why contract plans overcharge you
Telco contract plans in Singapore are priced to subsidise a handset and lock you in for 24 months — the plan component is inflated to cover the phone subsidy. Once you own the phone (or the contract ends), continuing to pay the contract price is equivalent to paying for a phone you are not receiving.
The Handset Subsidy Math: a $60/month contract plan includes a subsidised phone worth $600–$1,200. The subsidy is spread across 24 months ($25–$50/month). When the contract ends, the plan should drop to $10–$35/month for the same data. If it does not, you are effectively re-paying for a phone each renewal cycle.
MVNOs have reached near-parity with main telcos on network quality for typical Singapore urban use cases. The primary trade-off is customer service (typically online-only for MVNOs) and deprioritised data during peak congestion.
SIM-only vs contract, by the numbers
| Plan Type | Provider | Price/Month | Data | Contract | Network |
|---|---|---|---|---|---|
| Entry MVNO SIM-only | Giga (50GB) | ~$10 | 50GB | None | StarHub |
| Mid-tier MVNO | Zero1 (100GB) | ~$18 | 100GB | None | Singtel |
| Circles.Life (unlimited data) | Circles.Life | ~$25–$30 | Unlimited | None | M1 |
| Singtel SIM-only | Singtel (40GB) | ~$25 | 40GB | None | Singtel |
| StarHub SIM-only | StarHub (40GB) | ~$23 | 40GB | None | StarHub |
| M1 SIM-only | M1 (50GB) | ~$25 | 50GB | None | M1 |
| Standard telco contract | Singtel/StarHub/M1 | $55–$80 | 30–100GB | 24 months | Own |
The numbers show that a 50GB SIM-only plan costs $10–$25/month versus $55–$80/month for a comparable data contract plan — a monthly saving of $30–$70, or $360–$840/year per person. (Plan prices and data buckets are promotional and shift often; confirm current tiers on each provider's official site, linked in Sources, before switching. The network mappings — giga! on StarHub, Zero1 on Singtel, Circles.Life on M1 — reflect the 2026 market.)
Picking the right plan for you
Switch to SIM-only when your current contract has ended or is within 3 months of ending (early termination fees typically apply if you leave sooner). Stay on contract only if you need a phone upgrade and the subsidised phone price + plan cost is cheaper than buying the phone outright + SIM-only plan over 24 months (rare but possible during major phone launches).
| User Type | Recommended Plan | Monthly Cost | Annual Saving vs Contract |
|---|---|---|---|
| Light user (<15GB, mostly calls) | Giga 10GB or StarHub SIM-only basic | $8–$15 | $480–$780 |
| Average user (30–50GB) | Zero1 or M1 SIM-only 50GB | $18–$25 | $360–$660 |
| Heavy user (100GB+) | Circles.Life unlimited or Zero1 100GB | $25–$30 | $300–$600 |
| Frequent traveller | Singtel or M1 roaming-inclusive SIM-only | $30–$45 | $150–$420 |
What switching looks like in practice
In practice, this means a 30-year-old paying $65/month on a Singtel contract plan that ended 6 months ago should port their number to a SIM-only plan today. Switching to a $20/month plan saves $45/month — $540/year. The porting process takes 1–2 business days and requires no new hardware if the phone is unlocked.
For a household of 2 adults, both making this switch saves $900–$1,200/year — enough to cover 2–3 months of groceries.
When this does NOT apply
- You are mid-contract with early termination fees: Breaking a 24-month contract mid-cycle typically costs $150–$300 in early termination charges. Calculate whether the monthly savings over the remaining contract period outweigh the fee before switching early.
- You need a subsidised phone upgrade: If your phone needs replacement and a bundle plan's subsidised phone price + plan cost is cheaper than retail phone + SIM-only, the bundle may be justified. Always calculate total 24-month cost, not just the monthly plan price.
- You rely on telco customer service: MVNOs are typically online-only support. If you frequently need in-store service (e.g. elderly users, complex roaming setups), the main telco SIM-only plans are a reasonable compromise — still 40–50% cheaper than contract plans.
- You require a specific roaming package: Main telcos offer more comprehensive roaming add-ons and have clearer international coverage in less-common destinations. For frequent travellers to ASEAN or South Asia, roaming-inclusive main telco SIM-only plans may be better than MVNO + roaming top-ups.
Frequently asked questions
Will I lose my phone number when switching plans?
No — Mobile Number Portability (MNP) is mandated by IMDA as a free service for all Singapore mobile numbers (IMDA — Mobile Number Portability). You can port your existing number to any operator by requesting a transfer from your new provider. The process takes 1–2 business days; your number stays the same.
Is Circles.Life truly unlimited in Singapore?
Circles.Life's "unlimited" plans cap speeds at 1Mbps after a fair use threshold (typically 100GB/month of full-speed data). For most users, 1Mbps is sufficient for messaging and light browsing. Video streaming at 1Mbps is limited to standard definition.
Do SIM-only plans include IDD (international calling)?
Sometimes — check the plan terms. Most SIM-only plans include domestic calls and SMS but charge extra for IDD. If you frequently call overseas, add an IDD bundle (typically $3–$10/month) or use WhatsApp/Telegram calls via Wi-Fi instead.
Key takeaways
- If your contract has ended, switching to SIM-only immediately saves $360–$840/year per line with no service degradation for typical Singapore use.
- If you are on a Singtel, StarHub, or M1 contract, compare their own SIM-only tiers — even without switching operators, the SIM-only plan is $30–$50/month cheaper.
- If you are a light user (<30GB/month), MVNO plans from Giga or Zero1 offer the best value at $10–$18/month.
- For a household of 2, this switch is worth $900–$1,200/year — one of the easiest fixed-cost reductions available.
