Compare Best SIM Only Plans: Singapore 2026

Are you tired of long-term mobile contracts that don’t match your needs or budget? You’re not alone. With Singapore’s mobile penetration rate reaching 164%—the fifth highest in Asia—many are adopting flexible SIM-only plans.

However, the competitive market makes finding the best SIM-only plan in Singapore challenging. This comprehensive guide will compare the top 5 SIM-only plans for 2025, helping you make an informed decision that maximises value and aligns with your unique requirements.

What are SIM-Only Plans in Singapore?

SIM-only plans are mobile subscription plans with a SIM card but do not include a subsidised handset. These plans offer users greater flexibility, cost savings, and freedom from long-term contracts compared to traditional mobile plans.

With SIM-only plans, users can enjoy lower monthly fees as they are not paying for a bundled device. This allows them to choose their preferred handset separately or continue using their existing one. Additionally, most SIM-only plans do not require a contract, allowing users to switch providers or plans as their needs change.

Which is the Right Sim-Only Plan for You?

Choosing the best SIM-only plan depends on your individual needs and usage patterns. To make the right decision, you’ll need to assess your data needs, consider your calling and texting habits, evaluate network quality and coverage, and explore additional features offered by different providers.

Assess Your Data Needs

To determine the right data allowance for your SIM-only plan, start by tracking your monthly data usage. You can use your phone’s built-in data monitoring feature or your mobile provider’s app. Review your data consumption over the past few months to identify your average usage.

This will help you choose a plan with a data allowance that meets your needs without overpaying for unused data. Consider factors such as browsing habits, streaming preferences, and frequency of using data-intensive apps like social media or navigation services.

Consider Your Calling and Texting Habits

Evaluating your calling and texting habits, in addition to data usage, is crucial when selecting a SIM-only plan. Review your previous bills or use your provider’s app to determine your average monthly call minutes and SMS usage.

This information will help you choose a plan with sufficient call minutes and SMS allowances to avoid additional charges. Some plans offer unlimited local calls and texts, which may be suitable for heavy users, while others provide a set number of minutes and SMS messages that can be sufficient for light to moderate users.

Network Quality and Coverage

Network quality and coverage should be top priorities when searching for the best telco in Singapore. A reliable network ensures consistent access to voice calls, SMS, and mobile data services, even in remote or crowded areas.

To determine which telco offers the best coverage, visit their official websites and look for coverage maps or enter your address to check signal strength in your area. You can also consult online forums or ask friends and family about their experiences with different providers to make an informed decision.

Additional Features

When comparing SIM-only plans, don’t forget to consider additional features that can enhance your mobile experience or provide added value. Some plans offer international roaming options, allowing you to use your mobile services while traveling abroad at discounted rates or with special data packages.

Data rollover is another useful feature that lets you carry over unused data from one month to the next, ensuring that you get the most out of your plan. Some telcos also provide special add-ons or bundled services for streaming platforms like Netflix or Spotify, or social media apps like Facebook or Instagram, which can be particularly attractive if you frequently use these services.

Expert Tips for Maximising Your SIM-Only Plan in Singapore

Managing Data Usage

To make the most of your SIM-only plan and avoid unexpected charges, it’s essential to manage and monitor your data usage effectively. Here are some tips to help you stay within your plan’s data limits:

• Set data alerts: Most telcos offer the option to set data usage alerts via their mobile apps or online portals. By setting alerts at specific thresholds (e.g., 50%, 80%, and 100% of your data allowance), you can stay informed about your consumption and adjust your usage accordingly.
• Monitor your data usage regularly: Keep track of your data usage by checking your telco’s mobile app or online account dashboard. This will help you identify any unusual spikes in consumption and take corrective measures if needed.
• Use Wi-Fi whenever possible: Connect to Wi-Fi networks at home, work, or in public places to reduce your reliance on mobile data. This can significantly help you conserve your data allowance for when you truly need it.
• Disable background data: Some apps continue to use data in the background even when you’re not actively using them. Disable background data for non-essential apps to prevent unnecessary data consumption.
• Opt for lower video quality: Streaming videos in high resolution can quickly deplete your data allowance. Consider lowering the video quality settings on streaming platforms like YouTube, Netflix, or TikTok to consume less data without significantly compromising the viewing experience.

Leveraging Promotions

One of the best ways to maximise value and savings when choosing a SIM-only plan is to take advantage of promotional offers. Here’s some advice on how to leverage these promotions and where to find them:

• Check telco websites: Regularly visit the official websites of telcos like Singtel, StarHub, M1, and Circles.Life to stay updated on their latest promotions. Look for banners or dedicated promotion sections highlighting current deals and discounts on SIM-only plans.
• Follow telcos on social media: Follow the official social media accounts (Facebook, Instagram, and Twitter) of telcos to receive updates on promotional offers, flash sales, and limited-time discounts. These channels often feature exclusive deals that may not be available on their websites.
• Subscribe to newsletters: Sign up for telco newsletters to receive promotional offers and discount codes directly in your inbox. This ensures you never miss out on a great deal or limited-time offer.
• Compare plans on third-party websites: Utilize comparison websites like SIMPLYs Shop Samsung, GoBear, or CompareHero to browse and compare SIM-only plans from various telcos. These platforms often highlight ongoing promotions and help you find the best deals based on your usage needs.
• Look for bundle deals: Keep an eye out for bundle deals that offer discounts on SIM-only plans when combined with other services like home broadband or digital subscriptions. These bundle promotions can provide significant savings and added value.

Using the Right Credit Card for Payments

Using the right credit card to pay your SIM-only plan bills can help you maximise returns and enjoy additional benefits. Here’s how you can make the most of your credit card payments:

• Look for telco-specific rewards: Some credit cards offer bonus rewards or cashback specifically for telco payments. For example, the Citi Cash Back+ Mastercard provides 1.6% cashback on telco bills, while the OCBC 365 Credit Card offers 3% cashback on mobile and broadband subscriptions.
• Exploit online transaction rewards: Certain credit cards provide additional rewards for online transactions, which can be advantageous when paying your SIM-only plan bills through the telco’s website or app. The UOB EVOL Card, for instance, offers 8% cashback on online purchases, including telco payments.
• Utilise recurring bill payment benefits: Some credit cards offer bonus rewards or fee waivers when you set up recurring bill payments. The Standard Chartered Unlimited Cashback Credit Card provides 1.5% cashback on all eligible spending, including recurring telco bills, with no minimum spend requirement.
• Take advantage of sign-up bonuses: When applying for a new credit card, look for sign-up bonuses that can provide additional value when you use the card to pay your SIM-only plan bills. These bonuses may include cashback, reward points, or bill rebates.
• Redeem rewards for telco vouchers: If your credit card allows you to redeem rewards points for merchant vouchers, check if any telco-specific vouchers are available. You can then use these vouchers to offset your SIM-only plan bills or purchase additional services.

Conclusion

Choosing the best SIM-only plan in Singapore requires careful consideration of your usage habits, budget, and desired features. By evaluating your needs and comparing the various plans available, you can find the one that offers the best value for your lifestyle and ensures a seamless mobile experience.
