Hidden Costs to Watch Out For

While many mobile plans in Singapore advertise low monthly fees, it’s important to check the fine print.

Here’s what to look out for:

• Contract lock-ins: Some providers offer “no contract” on the surface but may hide cancellation penalties in the terms.

• Excess data fees: GOMO and Simba may throttle speeds or charge extra once you exceed your quota, unlike Circles.Life which offers add-ons and alerts.

• Limited roaming use: Even if a plan includes “free roaming,” it may only apply in certain countries or zones.

• eSIM activation fees: Some telcos may charge an onboarding or activation fee for eSIM plans.

Pro tip: Always check the full cost of ownership over 12 months—including hidden charges and any sign-up perks that expire after a few months.

How to Switch Without Losing Your Number

Porting your number to a new provider is easier than you might think.

Here's a quick guide to a smooth switch:

1. Choose your new plan: Pick the SIM-only plan or eSIM plan that fits your needs.

2. Register online: Most telcos (like Circles.Life) allow full digital sign-up through their app or website.

3. Request port-in: Select “Keep my number” during sign-up. Your number will be transferred, usually within 1 business day.

4. Insert SIM or activate eSIM: Once your old line is deactivated, pop in the new SIM or scan your eSIM QR code.

5. Confirm activation: Test your data and calls. You’re good to go.
