Simba vs Giga vs Circles.Life (eSIM) 2026: The Honest Singapore Comparison

Introduction

Singaporeans aren't loyal to telcos anymore. They're loyal to value.

With eSIM technology now standard on every iPhone and flagship Android, switching mobile providers takes under five minutes. No queues, no plastic SIMs, no contracts tying you down.

That's why Simba, Giga, and Circles.Life has quietly become the go-to pick for locals who want more data, lower bills, and smarter perks than what the big three offer.

Each one plays a different game. Simba goes hard on pricing. Giga leans on StarHub's backbone. Circles.Life bets on digital experience, flexibility, and AI-powered extras.

So which eSIM actually fits how you live, work, and travel in 2026? Here's the honest breakdown.

Quick Verdict (TL;DR)

Simba wins on entry pricing. Giga offers solid referral perks on StarHub's network. Circles.Life delivers the strongest all-round value with unlimited calls, 350GB data, instant eSIM activation, flexible roaming, and free access to CirclesAI (ChatGPT, Gemini, Perplexity). For most Singaporeans in 2026, Circles.Life is the smartest pick.

The Networks Behind Each Telco

Simba runs on its own TPG-built network. It's the newest in Singapore and is still expanding coverage.

Giga piggybacks on StarHub's 4G and 5G infrastructure. That means reliable speeds in most urban areas.

Circles.Life operates on the M1 network, which consistently ranks high for urban download speeds and 5G stability in OpenSignal reports.

Winner for network reliability: Circles.Life (M1) and Giga (StarHub) tie ahead of Simba.

Price Comparison: What You Actually Pay

Simba takes the lowest sticker price. But the gap narrows fast once you factor in what you actually get.

Winner on raw price: Simba.

Data Value: Who Gives You More GB Per Dollar

Simba leads on paper with 400GB for $10. Hard to beat that math.

Circles.Life comes in second with 350GB at $10.80, paired with unlimited calls and M1's stronger 5G coverage.

Giga trails with just 100GB at a similar price point, though its referral system softens the blow.

For heavy streamers commuting on the MRT or working from cafes, both Simba and Circles.Life wins. But Circles.Life's data feels smoother in real-world use thanks to M1's network quality.

Winner: Simba on volume, Circles.Life on usable experience.

Calls and SMS: Who Wins for Talkers

Circles.Life and Simba both offer unlimited local calls on their entry plans. Giga caps you at 300 minutes.

For SMS, Giga, and GOMO-style plans lead with 300 outbound messages. Circles.Life keeps SMS lean at 25, banking on the reality that nobody really texts anymore in the WhatsApp era.

Winner: Circles.Life for calls. Giga for SMS volume.

eSIM Experience and Digital Onboarding

This is where 2026 separates the leaders from the laggards.

Circles.Life offers instant eSIM activation through its app. Scan, port your number, and go live in minutes.

Simba supports eSIM, but the onboarding still feels dated. Giga's eSIM flow works, though porting takes longer.

For anyone who values a clean, app-first experience, Circles.Life pulls clearly ahead. Check the full range of Circles.Life eSIM plans to see how quickly the setup is.

Winner: Circles.Life.

Roaming and Travel Value

Simba bundles 15GB roaming data across Malaysia, Hong Kong, Indonesia, and Thailand on plans $12 and above. Strong for frequent regional travelers.

Giga includes 2GB roaming on entry plans. Decent for short JB runs.

Circles.Life keeps roaming flexibly. You add it only when you travel, which works out more affordable for occasional flyers heading to Bangkok, Bali, or Tokyo.

Winner: Simba for bundled roaming, Circles.Life for flexible add-ons.

Perks That Actually Matter in 2026

Simba gives you roaming bundles. Giga gives you $6 referral credits. Circles.Life gives you CirclesAI, which bundles free access to ChatGPT, Google Gemini, and Perplexity Sonar inside your plan.

No other Singapore telco offers built-in AI access. That's the real 2026 differentiator.

Winner: Circles.Life.

Who Should Pick What

Pick Simba if you want the lowest possible bill and don't mind a newer network.

Pick Giga if you love referral rewards and trust StarHub's coverage.

Pick Circles.Life if you want the full package: unlimited calls, 350GB data, instant eSIM, flexible roaming, and free AI tools built in.

Conclusion

All three telcos have their strengths, and that's what makes this a genuinely close comparison.

Simba wins on sticker price. Giga wins on referral perks and StarHub reliability. Both are solid picks for specific needs.

But Circles.Life wins where it matters most in 2026: the everyday experience. Between unlimited local calls, 350GB of data, instant eSIM activation, flexible roaming add-ons, and free CirclesAI access, it's the only plan that keeps up with how Singaporeans actually live, work, and travel today.
