Punggol residents can ask their telco to block incoming calls from international numbers. ScamShield’s official guidance says these blocking features are free and directs subscribers to their own provider for activation.
If you use Singtel postpaid, its current instructions put activation and deactivation in the My Singtel app’s Add-ons section. Check the selected number before making the change, especially when one account manages several family lines.
International call blocking also affects legitimate overseas callers. Before enabling it, consider relatives, overseas work contacts and travel arrangements. This is a line-protection choice, not a way to certify that every call which gets through is genuine.

Find your provider and exact line
Open your provider’s official app or support website independently. Ask specifically about incoming international call blocking; do not confuse it with an outgoing international-calling package.
For a Punggol household with several numbers, write down which line belongs to each person. Avoid changing a parent’s or child’s settings without explaining what the block is intended to do.

Check activation rather than assuming it
Follow the current instructions for your plan. Singtel states that subscribers can check the service status under Add-ons and receive an activation confirmation SMS.
Save the confirmation privately. If the app shows an unclear or pending status, ask the provider to confirm whether the requested block is active instead of trying to test it with a suspicious caller.

As practical preparation, tell regular overseas contacts about the change and agree on a trusted alternative contact method. Keep a record of any expected call and the organisation’s independently verified contact route.
ScamShield notes that calls from Singapore numbers used overseas can still arrive depending on the feature. Do not decide whether a call should have been blocked solely from where the caller says they are.

Review the setting before travel
If expecting international calls while travelling, ask your telco how the setting applies and how to change it. Put a reminder beside your travel checklist so a temporary change does not become an unnoticed permanent one.
Incoming-call blocking and international SMS blocking address different channels. Check both separately, and continue verifying unusual requests before taking action.
