Understanding SIM-Only Plans: What is a SIM Only Plan?

Before we dive in, let's clarify the essentials - what is a SIM only plan?

In essence, It's a straightforward mobile plan that provides you with just the SIM card itself. This gives you the flexibility to use this card with any unlocked mobile phone you currently own. This means you can easily upgrade or switch between devices without the hassle of changing your phone number.

SIM only plans come bundled with a monthly allowance of mobile data and talk time, and the best part is, they are highly customisable to suit your individual usage patterns and requirements. Here at Circles.Life, we go a step further. Our intuitive mobile application empowers you to effortlessly monitor your monthly data and call usage, conveniently manage your existing plan features, and even seamlessly switch to a more suitable SIM only deal whenever your needs evolve. So, if you're looking for a flexible and cost-effective way to stay connected, understanding what is a SIM only plan is the first step towards making the right choice.

Need more flexibility? Switch up to an eSIM option.

Benefits of choosing SIM-only plans

SIM-only plans can be extremely advantageous. Some of the benefits that you’ll enjoy when choosing this option include:

• Affordability: Without subsidising a phone, these SIM-only plans are typically more affordable and offer more value than combo deals.
• Flexibility: Without annual contracts, you can easily switch between SIM-only deals as per your monthly requirements.
• Optimised Usage: Make the most of your data and talk time every month with SIM-only plans.
Last but not least, SIM-only plans are less risky. Imagine relocating to a neighbourhood where your current provider's signal is weak. With Circles.Life, all you need to do is select your preferred plan, swap your SIM card or activate your eSIM, and you are good to go!

Considerations before choosing SIM-only plans

SIM-only plans are a great option for most users, but there are some considerations to consider. Here’s what you need to know:

• Device Costs: If you're eyeing a new phone, remember you'll bear the full cost upfront with SIM-only plans.
• Network Compatibility: Ensure your device supports the network offerings of your chosen SIM-only provider before committing. For example, ensure you have a 5G-compatible smartphone before selecting a 5G plan.

Who should opt for SIM-only plans?

If you've recently splurged on a phone or dislike contractual ties, SIM-only plans might be your match. Temporary residents in Singapore or those frequently swapping phones can benefit immensely from this flexibility.

However, if you're aiming to snag a deal on the latest phone models, consider our combo plans that pair top-tier devices with our fantastic SIM-only offers. Otherwise, check out our most popular SIM-only plans below!
