Circles.Life
App-first SIM-only mobile plans on the M1 network — no contract, change plans anytime.
Circles.Life is Singapore's best-known MVNO (mobile virtual network operator) — a telco that runs on M1's physical network but sells its own plans, launched in 2016. Coverage and call quality are the host network's; what changes is the packaging: no-contract SIM-only plans managed entirely from an app.
The app-first model is the point. Signing up, changing plans, adding data boosts and troubleshooting all happen in the Circles.Life app — there are no retail stores. For people who never visit a telco shop anyway, that trade usually reads as a discount for skipping overheads they never used.
What Circles.Life Offers
- SIM-only mobile plans — a range of data tiers up to unlimited, all without a fixed-term contract.
- eSIM and physical SIM support — activate without waiting for delivery if your phone supports eSIM.
- Flexible add-ons — data boosts and roaming add-ons purchased from the app when you need them.
- Number porting — keep your existing number when you switch; porting is handled during sign-up.
Is an MVNO Right for You?
MVNOs like Circles.Life use the same cell towers as the big three telcos, so day-to-day network experience is essentially identical. The genuine differences are support (online-only, no physical stores), perks (fewer bundled extras like entertainment subscriptions), and price flexibility (no contract means you can leave any month).
If you already own your phone and your usage is predictable, a SIM-only MVNO plan is one of the simplest recurring-bill cuts available in Singapore. Compare Circles.Life against GOMO, Zero1 and the telcos' own SIM-only tiers for your data needs before deciding — our mobile plan guide walks through the whole market.
Good to Know
- Plan pricing, data allowances and promotions change frequently — always check the current line-up on Circles.Life's site rather than relying on screenshots or old articles.
- Coverage is M1's network — if M1 works well where you live and work, Circles.Life will too.
- Support is app/online-only. If you want counter service, a mainline telco may fit better.
- No contract cuts both ways: you can leave anytime, and pricing isn't locked in long-term either.
