Tired of being locked into a long-term phone contract? SIM-only plans give you more control over your mobile bill, without tying you to a handset bundle or multi-year commitment.
Singapore’s SIM-only plan scene remains competitive, with several providers offering large data bundles for under $10/month. We’ve refreshed the latest prices, data allowances, roaming perks and promotional terms.
With many options available, choosing a SIM-only plan isn’t just about finding the lowest monthly fee. Data allowance, roaming perks, network access and promo terms can all affect how much value you actually get.
We compare Singapore’s most affordable SIM-only plans by price, data and key features to help you decide which one works best for your usage and budget.
[ms-toc title="Cheapest SIM-Only Plans in Singapore 2026"]
First, what’s a SIM-only plan?
A SIM-only plan gives you mobile data, talk time and SMS without bundling in a new phone. That makes it a cost-friendly option if you are happy with your current device and want to avoid paying for a handset through a long-term contract.
Plans now range from basic data-first options under $10/month to larger bundles with hundreds of GB for streaming, hotspot use and heavy daily browsing. Many budget plans also include regional roaming data, especially for nearby destinations such as Malaysia, Indonesia, Thailand and Hong Kong, although the allowance and validity can vary widely by provider.
The best plan depends on how much data you use, whether you still need calls and SMS, how often you travel, and whether the advertised price is permanent or for a limited time only. We arranged the plans from the lowest monthly price upwards, while noting key data, roaming and promo conditions where relevant.
Here are the top most affordable SIM-only plans
Prices are accurate as of June 2026 based on each telco’s official website or latest published plan terms available at the time of writing. Some are promotional rates, port-in offers, age-based offers or limited-period pricing.
Always refer to the official sites for the latest pricing and terms.
Now that we’ve rounded up the cheapest SIM-only plans under $15/month, let’s take a closer look at what each telco offers, including plan breakdowns, roaming perks, and whether the listed prices are promotional.
1. ZYM SIM-only plans (from $7/month)
ZYM is a good place to start if your priority is keeping the monthly bill as low as possible. Its entry-level plan starts from $7/month, which makes it the cheapest option in this list, although the best pick depends on whether you need a full everyday mobile plan or just affordable data.
ZYM’s $7/month Flexi Duo plan is best treated as a data-first option for users who do not rely heavily on calls or SMS. For everyday users who still want talktime, SMS and roaming coverage, Roam Saver at $7.77/month is the more rounded pick.

Best SIM-only plans comparison
Wondering which plan is best for you? Here’s a quick guide to help you decide the most-suited plan:
Cheapest SIM-only plans for users with low data requirements
Starting with the lowest monthly subscription fees, so you can quickly see the cheapest options first. We also look at how much local data, talktime and SMS they include, since these can affect how useful the plan is day to day.
Cheapest SIM-only plans for those with higher data needs
Since these plans are meant for heavier usage, check out how much data you get for the price, especially when the monthly cost is close.
Here are some plans that offer much higher data for an affordable cost:
Before you commit, do a quick scan beyond the monthly price. A plan that costs a little more may save you from running out of data, paying for roaming add-ons, or realising too late that “cheap” came with too many compromises.
Best credit cards for telco bills payment
Charging recurring telco bills to the right credit card can still earn cashback, but the best card depends on your monthly spend, telco, payment method and whether the bill is charged as a recurring payment.
Card rewards for telco bills generally fall into two buckets:
- Cards that reward recurring telco or utility bill payments
- General cashback cards that may cover telco bills as part of broader eligible spend
Eligibility can vary by telco, payment method, merchant category code and whether the bill is paid directly, through an app or through a third-party payment platform.
