Punggol residents can use the official SIMCardHowMany service to check registered postpaid SIM cards included within Singapore’s postpaid SIM limit. Start from the government link and follow the current verification instructions.
Since 28 February 2026, the limit is ten postpaid SIM cards per person across all telcos. MDDI confirms this is a combined limit, so counting only the lines with one provider gives an incomplete picture.
If the result includes a number you do not recognise, contact the named telco through its official support channel. Ask it to verify the registration before deciding whether the line is forgotten, unfamiliar or potentially unauthorised.

Prepare a household comparison
Make your own list of the mobile subscriptions you expect to see. Include lines you pay for but that another family member uses, and record which person is the registered subscriber.
Use that list to check the result carefully. Keep the registration details private rather than posting a screenshot of the complete result in a public group.
Follow the current checker steps
MyRepublic’s published guide describes Singpass verification, an email address and an email verification code, followed by an emailed result. Follow the live service if its screens have changed.
Use an inbox you can access and check the address entered before submitting. If nothing arrives, note when you made the request and use the official help route for the checker.
Query an unfamiliar number
Tell the provider which entry you are asking about and request verification of the relevant registration details. MyRepublic notes that it authenticates the customer before sharing detailed information.
Keep the support reference and response. If registration is confirmed as fraudulent, MyRepublic advises making a police report; preserve the provider’s findings for that report.
Review lines you no longer need
For a legitimate unused line, ask the provider about termination, remaining obligations and any connected services. Check whether a family member still relies on it before making a change.
Record the completion date and review the subsequent bill. If a phone or SIM is actually missing, use the separate lost phone and SIM suspension guide promptly.
