Who Should Consider These Roaming Plans?

Not all travel SIMs are built for the same kind of user. Whether you're crossing borders weekly or just need reliable data abroad once in a while, here's how the two plans stack up based on your lifestyle.

SIMBA SuperRoam 10 – Ideal For Budget Roamers

SIMBA’s SuperRoam 10 is best suited for users who prioritize low cost and maximum local data:

• Frequent travelers to Malaysia, such as students, workers, and daily commuters

• Anyone who needs a large local data pool such as 200GB for just $10 is unmatched

• Users who occasionally travel to places like Hong Kong, Macau, or Taiwan

• People with minimal need for voice calls, premium perks, or concierge support

If you’re mostly in Singapore or just across the Causeway, SIMBA keeps things simple and affordable.

Circles Borderless – Ideal for Business & Frequent Travelers

Circles.Life’s Borderless Plan is designed for users who want seamless coverage across multiple countries with premium features built in:

• Frequent flyers across Asia-Pacific, including Australia, Thailand, South Korea, and more

• Anyone who wants a single SIM for both Singapore and roaming destinations

• Remote workers or business travelers who require consistent, high-speed roaming data

• Those who value extras like concierge support, call/SMS inclusions, eSIM flexibility, and delivery

If convenience, speed, and a full-service experience matter more than price per GB, Circles.Life delivers more value with less hassle.

SIMBA vs Circles.Life: SG Roaming Plans, is the Price Worth It?

When it comes to roaming SIMs, both SIMBA and Circles.Life offer strong value but in very different ways.

SIMBA SuperRoam 10 is one of the most affordable SIM-only roaming plans in Singapore. For just $10/month, you get:

• 280GB data for use in SG and MY

• 3GB roaming in over 60 countries

• 500 mins IDD calls to over 20 countries

• No contract or hidden fees

The tradeoff? Limited roaming data beyond Malaysia and no premium extras like call concierge, roaming management, or lifestyle perks.

Circles.Life Borderless Roaming, on the other hand, starts at $30/month and delivers a premium roaming experience:

• 100GB data usable in SG + 7 destinations (5G included on eligible plan)

• 300 mins outgoing calls + unlimited incoming

• Free delivery, eSIM support, concierge help

• Bonus features like CirclesAI and rewards vouchers

While Circles.Life costs more upfront, you get more roaming data freedom, easier SIM management, and perks that reduce friction while traveling.

So, is the price worth it?

• If you need a lot of local data and only roam occasionally, SIMBA gives unbeatable value for just $10.

• If you travel often and want one SIM for everything, Circles.Life offers convenience, coverage, and better support, especially with 5G roaming.

Did You Know:

5G roaming is still rare in budget plans. While many telcos offer local 5G, only a few, including Circles.Life Borderless, support 5G access abroad, giving you faster speeds in countries like Australia, South Korea, and Thailand.

SIMBA vs Circles. Life: Network Coverage & Data Speed

Roaming plans aren’t just about where you can go. They’re also about how fast you can connect once you get there.

SIMBA SuperRoam 10 – Basic Coverage, Practical Speeds

SIMBA operates on its own network in Singapore and relies on partner carriers abroad. While 5G is available locally, international roaming typically connects at 4G speeds, depending on the destination’s infrastructure and partner agreement.

• Singapore: 5G included with no extra charge

• Overseas: Mostly 4G; quality varies by country

• Roaming quota is limited (3GB), and speeds may throttle after

Circles.Life Borderless – Strong 5G and Consistent Experience

Circles.Life is powered by M1’s network in Singapore and offers strong coverage in both local and roaming markets. The Borderless 5G plan includes 5G speeds in Singapore and selected countries. It is perfect for heavy data users and streamers on the go.

• Singapore: Access to M1’s 5G UltraSpeed network

• Overseas: 5G or 4G available across key Asia-Pacific countries

• Roaming speeds are stable, with up to 1–3GB/day allocation

The Verdict on Speed and Coverage

• SIMBA is suitable for users who can work with basic 4G connectivity when abroad and don’t mind speed variations.

• Circles.Life is built for those who want high-speed, consistent performance across borders, especially useful for work, streaming, or staying connected in real time.

Ease Of Sim Activation Process & Roaming Management

How easy is it to get started and stay connected while abroad? Let’s look at how each provider handles SIM activation, roaming setup, and user convenience.

SIMBA SuperRoam 10

SIMBA keeps things simple but a bit manual.

• Requires a physical SIM (no eSIM support yet)

• Roaming must be activated via SMS or online portal

• Top-up is required once the 3GB roaming limit is used up

• No mobile app-based control for roaming allocation

• Suitable for users who are familiar with basic telco processes and don't mind manual toggles

Circles.Life Borderless Roaming

Circles.Life offers a much smoother, app-based experience.

• Choose eSIM or physical SIM at checkout

• Roaming is automatically enabled for supported destinations

• Use the Circles.Life app to manage data, track usage, or toggle roaming

• Premium plan holders get concierge support, free SIM delivery, and travel setup help

Which One’s Easier?

If you want full control from your phone without needing to text codes or log into portals, Circles.Life is clearly the more user-friendly option. SIMBA is functional but requires more hands-on management, especially when roaming data runs out.
