When it comes to choosing a mobile plan in Singapore, the decision often comes down to two options: SIM-Only plans or 2-year contract plans with subsidised devices. While SIM-Only plans have gained popularity for their low prices and flexibility, contract plans still appeal to users looking for cheaper phone upgrades.
In this article, we break down both options to help you decide which offers better value in 2025.
What’s the Difference Between SIM-Only and 2-Year Contract Plans?
Here’s a quick overview:
| Feature | SIM-Only Plan | 2-Year Contract Plan |
|---|---|---|
| Monthly Price | From $18–$35 | From $68 and up |
| Contract Commitment | None | 24 months (recontract after 21 months) |
| Phone Included | No | Yes (subsidised) |
| Data Allowance | 100GB to 300GB+ | 30GB to 60GB (some with unlimited weekends) |
| Flexibility | Cancel anytime | Early termination fees apply |
| Extras | Roaming add-ons, caller ID, occasional perks | Disney+, security apps, roaming bundles |
Although it’s commonly called a 2-year plan, most telcos in Singapore allow recontracting only after 21 months. This means you’re tied in for nearly two years before you can get another subsidised phone.
If you like changing devices frequently or want the freedom to switch telcos, this lock-in period can feel restrictive.
Comparing Costs: SIM-Only vs Contract Over 2 Years
Let’s say you’re eyeing a flagship phone worth $1,800. Here’s how the total cost stacks up:
| Plan Type | Monthly Fee | Phone Cost | Total Over 2 Years |
|---|---|---|---|
| SIM-Only | $20 | $1,800 (retail or 0% instalment) | $2,280 |
| Contract Plan | $68 | ~$500 (subsidised) | $2,132 |
At first glance, the contract plan looks cheaper by about $150. However, that comes with trade-offs — less data, limited flexibility, and fewer ways to take advantage of promos from third-party retailers or banks.
When Is a SIM-Only Plan Better?
Choose a SIM-Only plan if you:
- Already have a working smartphone
- Want to save more on monthly bills
- Need large data allowances (e.g. 100GB and above)
- Prefer switching telcos without penalty Can buy your phone separately via retail or credit card instalments
Thanks to competition from MVNOs and sub-brands, SIM-Only plans now offer tremendous value, with plans starting at $18 and offering more data than most contract plans.
When to Consider a 2-Year Contract Plan
A 2-year contract may suit you if you:
- Prefer a discounted phone and lower upfront cost
- Don’t switch telcos often
- Use under 60GB of data per month
- Want bundled perks like Disney+, caller ID, or overseas roaming
- Don’t mind waiting 21 months to upgrade again
Some telcos also offer limited-time promotions, such as trade-in bonuses or cashback, which can make contract deals more attractive — but it’s important to compare the total cost carefully.
Final Verdict: SIM-Only Plans Remain the Smartest Option in 2025
Unless you need a new phone immediately and can’t afford to pay full price upfront, SIM-Only plans continue to offer better value in Singapore today. They are:
- More affordable over time
- Packed with larger data allowances
- Free from long-term lock-ins
- Often compatible with 0% interest phone instalments via retailers
In 2025, telcos have also started offering device financing without contracts — meaning you can get a phone and a SIM-Only plan with full freedom.
