What is a SIM Only Plan?

A SIM only plan is exactly what it sounds like: a mobile subscription that gives you just the sim card only, without a bundled phone. This means no lock-in contracts, no inflated handset costs, and much more flexibility. You simply pop the SIM into your existing phone and enjoy affordable calls, texts, and data.

The best sim only plan is particularly appealing if you already own a smartphone or prefer buying devices outright rather than through contracts.

Why Choose a Cheap SIM Only Plan?

Choosing the cheapest sim only plan singapore has clear advantages:

• Cost savings: Monthly bills are typically half of traditional contract plans.

• Flexibility: No need to commit for 12–24 months. Switch anytime.

• Choice of phone: You can upgrade your device whenever you want, without waiting for contract expiry.

• Simplicity: You only pay for what you need—data, calls, and texts.

In a competitive market like Singapore, cheap SIM only plans are more available than ever thanks to the rise of MVNOs.

The Rise of MVNOs (Virtual Telcos)

Mobile Virtual Network Operators (MVNOs) lease bandwidth from major telcos (like Singtel, StarHub, and M1) but sell it at lower prices. Popular MVNOs include Circles.Life, Giga, Zero1, MyRepublic, and RedONE.

These providers are reshaping what the best sim only plan Singapore looks like: high-data bundles, low monthly fees, and bonus perks like free roaming or unlimited music streaming.
